Best Insulation for a Crawl Space

Written by Kevin on . Posted in Insulation. No Comments on Best Insulation for a Crawl Space

If your home has a crawl space, you probably don’t pay it much attention. The crawl space, as the name would imply, is uncomfortable to access, and usually hot, sometimes damp, and almost always dirty. Though it might be tempting to deal with your crawl space at a later date, ignoring issues in your crawl space insulation can result in significant problems down the road. 

The air in crawl spaces has to go somewhere, and in a vented crawl space that air usually goes upward through the flooring. The problem lies not in the air that passes through crawl spaces, but the moisture it carries with it. Recognizing and minimizing that moisture is essential in order to avoid the worst outcomes associated with a dirty and unkempt crawl space: lots of mold growth, a damaged crawl space floor, poor air quality in your home, and ineffective insulation.

What is a Crawl space?

Homes may be built on different types of foundations. Typically in the United States, homes are either built on a concrete slab-on-grade, with a basement, or on a crawl space. Crawl spaces create a gap between the ground underneath your home and the floor of your house. Crawl spaces may be as little as a foot off of the ground, or as high as three feet.

While crawl spaces may not be common in every home, they tend to be more common in areas where elevated levels of moisture in the soil and wreak havoc on slab foundations or basements. 

There are two basic types of crawl spaces:

  • Vented – A vented crawl space is one that is not conditioned and where air circulates from outside. This is the most common type of crawl space, but it can also be very problematic. This type of space may need crawl space repair as time goes on and moisture builds.
  • Unvented – Unvented crawl spaces are a conditioned part of your home and don’t circulate air with the outside. These types of crawl spaces are best thought of as a mini-basement. Though there are advantages with an unvented crawl space, they are less common and require more initial labor and materials to construct.

Let’s take a moment to dig into how a vented crawl space is set up since that is the most common type. A ventilated crawl space will typically consist of the ground at the lowest level, which may be covered with gravel, a moisture barrier, or a dirt floor. Above the ground will be a 1-3 foot gap. Above that gap is the subfloor below the first floor of your home, followed by whatever type of flooring you put in. 

Most vented crawl spaces passively circulate air with the outside, meaning a simple opening to the outside is present at various points around the crawl space and no equipment is used to facilitate air circulation. Some crawl spaces are completely vented and open to the outside, but most have only a few venting points around the home. 

Crawl spaces can have some advantages over slab-on-grade foundations or basements. These include:

  • A lower price point. Crawl spaces are cheaper than an unfinished basement and may be cheaper than a slab-on-grade foundation depending on your excavation needs.
  • Crawl spaces give you access to functional systems of your house, including ducting, electrical, plumbing, and insulation. This can result in cheaper major repairs if you have a problem with one of these systems or components of your home.
  • Crawl spaces are used in areas with large amounts of moisture or certain soil types rather than other foundation types that lack venting.
  • Crawl spaces can be installed in colder regions where the freeze-thaw cycle can damage a traditional slab-on-grade foundation. In this instance, a basement would not be ideal and instead, a ventilated crawl space would be the most ideal. 

Moisture and Crawl spaces

One of the most common reasons a crawl space is used rather than a basement or concrete slab foundation is due to the moisture level in the surrounding environment and soil. In very wet areas or coastal areas with sandy soil, a vented crawl space may be necessary to help avoid moisture leaching into the basement or slab. 

While crawl spaces may be used to solve moisture issues, if they aren’t properly set up they can introduce their own moisture problems into your home. 

The problem lies in the temperature difference between the air inside your crawl space and the outside air. During the warmer months of the year, the ground in the crawl space area is colder than the air outside. As outside air enters the crawl space area, it brings with it moisture. That warm, moist air cools when it enters the crawl space until it hits the dew point and forms condensation. 

Modern houses built on crawl spaces place insulation, usually fiberglass batt insulation, in between the floor joists. Due to the fact that the ground in crawl spaces is usually a few degrees cooler than the underside of your floor insulation, condensation will begin to form on the underside of your floor joists and insulation. Over time that condensation will lead to mold growth. Eventually, the moisture in your subfloor may also impact your crawl space floor, particularly if your flooring is something impermeable to moisture like vinyl.

What is the Best Insulation for a Crawl Space?

If you’re looking for the best insulation for crawl space, it’s important to consult with the experts. Here at Attic Construction, we’ve used fiberglass batt insulation successfully in crawl spaces for many years. That being said, it is possible to use other types of insulation material, such as foam, in a crawl space. 

However, crawl spaces have unique considerations that make it a good idea to consult with professionals before any installation takes place. Specifically, in order to eliminate any build-up of moisture in your crawl space, it’s important to effectively manage the moisture levels in that space. Unmanaged moisture in the crawl space will lead to mold growth on your floor joist and insulation material, and that moisture will seep up into the subfloor. This situation can potentially lead to serious damage requiring extensive and costly repairs.

How Should I Insulate My Crawl Space?

If moisture is such a problem, you might be wondering about the best way to insulation crawl space. According to the Building Science Corporation, a building science consulting firm that promotes building best practices, the ideal way to insulate your crawl space is to make it a conditioned part of your home. The best practice is to treat the crawl space as a mini-basement, which involves eliminating venting to the outside, ensuring ground vapor is sealed, insulating and air sealing the walls of the crawl space and treating that space with conditioned air. 

Of course, your home may have a vented crawl space, in which case it may be impractical to switch to an unvented crawl space. In unvented crawl spaces, effective moisture mitigation can be accomplished through the use of a vapor barrier in addition to the fiberglass batt insulation. 

An effectively installed vapor barrier can help eliminate the buildup of condensation on your floor joists or insulation, eliminating the mechanism through which mold growth and damage to your subfloor and flooring occurs. Poor crawl space insulation can be a disaster for you and will ultimately lead to a need for crawl space repair down the road. Find out what type of crawl space your house has and take the necessary steps to complete proper insulation before a problem arises. 

The Importance of Professional Installation

To avoid any costly repairs down the road, it is incredibly important to have your crawl space insulation installed by professionals. Poorly installed crawl space insulation may contain air gaps that allow moisture to penetrate upwards into your home. That moisture will condense, and eventually lead to mold growth in the subfloor, joists, or existing insulation. It may also impact your flooring, particularly if you have flooring such as vinyl which doesn’t allow moisture to pass through. 

It is also important to recognize existing damage and put in place remediation measures before you install new insulation. If you have existing problems with moisture buildup in your crawl space, there may be more work to do before you can begin installing proper insulation. Keep in mind that working in a crawl space is difficult. Crawl spaces are usually cramped, tight spaces that may contain exposed plumbing, electrical, and ducting you’ll have to work around. 

Finally, it’s important to start with a new, clean foundation before starting your new installation process. Check out a crawl space cleaning service to help aid you in the new insulation process.

Closing Thoughts

Crawl spaces are a common type of housing foundation that consists of a gap between the ground and the subfloor of a home. Crawl spaces are typically used in areas where weather and soil conditions make a concrete slab-on-grade foundation or basement impractical. The most common types of crawl spaces are passively vented, which allows air to circulate in from the outside. In the summer months that warm air mixes with the colder air in the crawl space and forms condensation as it cools. 

While the insulation you use in a crawl space is important, it’s even more important that you have your insulation, and vapor barrier if required, installed by a team of professionals. When crawl space insulation isn’t installed correctly it can allow air and moisture to pass through to the subfloor of your home. Over time that moisture can result in the buildup of mold, impacting the air quality throughout your home. That moisture may also result in extensive damage to your subfloor and flooring.

Insulating your crawl space correctly isn’t easy, but it is possible. Leave it to our professional team at Attic Construction.

Is Attic Radiant Barrier Worth it?

Written by Kevin on . Posted in Attic Insulation, Barrier Insulation, Radiant Insulation. No Comments on Is Attic Radiant Barrier Worth it?

If you’ve spent time thinking about protecting your attic against the elements, you may have heard about “radiant barriers.” 

Many people are skeptical whether installing this reflective material is worth the cost. In some states, predatory contractors have been decried by government agencies for using misleading marketing about what radiant barriers can do.

So, is radiant barrier worth it? 

In San Diego and Orange County, absolutely. Radiant barriers work by reflecting the sun’s rays, making them ideal for bright, hot climates. When installed properly and in the right regional context, a radiant barrier will pay for itself…

Radiant Barriers Cut Down Cooling Costs

There’s no question that radiant barriers cut down on cooling costs during the hottest months. The Department of Energy has suggested that in sunny regions, installing radiant barriers reduces cooling costs by 5% to 10%. 

In the hottest areas, those energy savings can be even greater.

These energy savings benefits do not apply to the entirety of the United States, contributing to a discourse of whether radiant barriers are worth it. If you are debating this for yourself, consider these following questions:

  • Is my home in direct sunlight throughout most of the day?
  • Do I live in an area that reaches above 100°F for multiple weeks at a time?
  • Does my attic have ductwork or HVAC equipment installed in it?

If you’ve answered yes to any of these questions, there is a good chance that your home will benefit from radiant barriers.

Direct Sunlight

If my house is in direct sunlight, shouldn’t reflective radiant barrier material be on the outside of it? As it turns out, it doesn’t need to be. Radiant heat moves through the surface of your roof deck to heat up your attic, entering your home and spiking cooling costs. 

Radiant barriers block the heat from coming in. 

Sunlight is one of the silent means that heat enters your home. Anyone who has opened the door to a vehicle and watched heat pour out knows that thanks to sunlight, enclosed spaces like cars can become small furnaces in the dog days of summer.

If your home receives direct sunlight throughout the day, especially if you don’t have any trees shading your roof deck, you should consider radiant barrier installation for cost reductions.

Hot Climates

If you’re in a region where it’s hot for most of the year, radiant barriers will provide year-round cooling cost reductions. If you experienced the brunt of the polar vortex in 2019, you may be better off with other types of insulation that are more cost effective for your region.

Some contractors in the industry were recently criticized by the Division of Energy Resources for installing radiant barriers when they were not necessary. While both can be used together effectively, as attic insulation increases, the effectiveness of radiant barriers decreases.

Radiant barriers aren’t snake oil—they work in the regions where you need them. You don’t need to bring a winter coat on a trip to the beach, and you don’t need radiant barriers in regions of the United States with a cold climate.

Ductwork/HVAC Equipment

Some homes, especially older ones, have ductwork running through the attic space. If you live in a home like this, radiant barriers will be particularly valuable for lowering cooling costs in the hotter months.

Attics that are not protected against the heat are going to put extra strain on air conditioning in the summer. As the attic space heats up, the ductwork heats up alongside it, and the machines pushing out the cold air into your home have to work twice as hard to produce the same level of climate control in your home.

When HVAC ducts aren’t insulated, cool air can escape from them and the need for a machine to turn on and off increases. This causes wear and tear on these machines, necessitating more maintenance and less effectiveness over time.

How You Can Lower Costs Even Further With Radiant Barriers

If you’ve been wondering “does radiant barrier work?” the answer is yes—radiant barriers will reduce your heating costs in the hottest months. The degree to which that will benefit you is regionally dependent, but if you live in San Diego or Orange County, there is a high likelihood that installing radiant barriers will slice your cooling bill. 

Benefits include:

  • Cooling costs reduced by at least 5%-10%
  • HVAC systems get less wear and tear over time
  • Smaller or more energy-efficient cooling can supplement existing systems while providing the same (or better) air conditioning than before

But why stop saving there? Hiring experts like Attic Construction can help ensure you get it installed right the first time, with professionalism that can’t be beat.

Radiant Barrier vs Insulation: What’s the Difference?

Written by Kevin on . Posted in Attic Insulation, Barrier Insulation, Radiant Insulation. No Comments on Radiant Barrier vs Insulation: What’s the Difference?

When we think about protecting our homes from the elements, our thoughts tend to go towards insulation against the cold. Anyone with a drafty window in the middle of winter can appreciate the value of a tightly sealed home. 

But did you know that there are ways you can also keep your house cooler in the summer?

Radiant barriers can be installed alongside insulation in the attic space, providing a heat shield that can lower cooling costs in the summer months. Today, you’ll learn about the benefits of radiant barriers and insulation, and how both can reduce heating and energy costs!

Radiant Barriers Are Not The Same As Insulation

When weatherizing a home, the primary objective is to make it as comfortable as possible throughout the four seasons. Aside from central heating and cooling, there are two different kinds of building materials commonly used to perform this task: insulation and radiant barriers.

While both perform the same function—keeping your home at a reasonable temperature—the ways this is done vary greatly between the two. 

This is because heat does not spread in a uniform way.

  • Insulation blocks conductive heat – Insulation is like a down coat for your home. By providing a thick layer of insulation material, heat is slowed down and penetrates through your walls more slowly. The higher the value of resistance, or R-value, the slower it enters your home.
  • Radiant barriers block radiant heat – Park your car outside for a few hours on a hot summer day, and you’ll return to a furnace. Radiant barriers bounce the rays of the sun back from where they came from, even when installed underneath roofing. Rather than slowing heat, they prevent it from entering your home. On average, radiant barriers reflect around 95% of radiant heat.

Radiant heat is the single greatest source of heat accumulation in a home, while conductivity causes the greatest amount of heat loss. Yet between the two, most homeowners opt for insulation rather than radiant barriers. 

Why is this the case?

On average, Americans spend more on their heating costs than they do on their cooling costs. This has a lot to do with regionality. Energy bills in the United States vary greatly from one end to the other, but residents of San Diego and Orange County are far more likely to have high air conditioning costs than a resident of North Dakota.

Radiant Barriers and Insulation Control Heat in Both Directions

While insulation is most commonly associated with winter and radiant barriers with the summer, it is incorrect to assume that they don’t function outside of their seasons.

After finishing a marathon, racers are often covered in a reflective surface or blanket. This isn’t to protect them from the heat, but to raise their core temperature. After extreme exercise, the body releases heat faster than it can retain it, which can lead to shock. This blanket reflects the heat back in.

Much in the same way, homes in the Midwest can cover the joists of their attic floor with reflective barriers to keep radiant heat from exiting through the roof during the cold winter months. This means radiant barriers serve a dual purpose—keeping the summers cool and the winters warm.

By slowing heat, insulation helps keep the air conditioning unit running less in the summer, but it will also keep heat trapped in your home longer without it. This is why in warmer climates, a mixture of both insulation and radiant barriers tends to produce the greatest value.

Radiant Barrier vs Insulation: Which Do I Need?

Deciding on whether you should install a radiant barrier or insulation is not a zero-sum game.

Radiant barriers aren’t required in colder states, and even in the hottest states aren’t found in every home. However, they provide significant benefits in terms of energy savings and comfort levels to those that do. Virtually all residents of California will benefit from installing radiant barriers in their attic space.

Insulation is recommended for all homes, although how much is needed varies from location to location. The Department of Energy has split the U.S. into seven zones as a guideline for how much insulation is necessary for your attic. The amount of insulation is referred to as an “R-value.” For Californians, it is recommended that they meet attic insulation levels of R-30.

Your home should meet the minimum insulation requirements to keep bills low. 

To determine whether you need an attic radiant barrier, ask yourselves these questions:

  • Am I paying too much for my electric bill in the summer?
  • Do the rooms directly beneath the attic tend to get hotter during the day?
  • Does my home receive direct sunlight throughout most of the year?

If you answered yes to any of these questions, an attic radiant barrier may be the solution to your cooling needs.

Radiant Barriers and Insulation Are Good For The Environment

Most homes in the United States have insulation, and many homes do not have radiant barriers. But over the past few years, this statistic has begun to change. As Americans are becoming more conscious of how their energy usage contributes to climate change, many have begun installing radiant barriers or better insulation to decrease their carbon footprint.

In 2009, air conditioning constituted around 6% of all residential energy usage. 

This adds up to about 100 million tons of carbon dioxide released into the atmosphere every year. Since then, that number has only gone up. Heating costs constitute an even greater percentage of energy spent, and both are largely fueled by burning coal.

Since these pronouncements, some homeowners have gone out of their way to make their homes as carbon efficient as possible. To this end, many start by looking at ways to decrease their heating and cooling costs. For those looking to save the environment, residents of colder states tend to install radiant barriers even though they do not produce the same cost savings.

The Bottom Line: the Value of Radiant Barriers and Insulation

While some people use radiant barriers and insulation to control the temperatures of their home for comfort, and others for environmental reasons, others are more concerned about the bottom line. How much money can you expect to save by installing radiant barriers or better insulation?

Besides your region, there are several factors that play into this. On average, radiant barriers have been shown to decrease cooling costs by around 10%. Homes with these features are likely to see the greatest savings after installing radiant barriers:

  • Ductwork/HVAC Equipment in Attic – Older homes are more likely to store air conditioning equipment in the attic. This is an energy efficiency nightmare. Because attics are typically the hottest parts of your home, your air conditioning units will have to work harder to keep your home cool, increasing energy expenditure and maintenance costs. Radiant barriers will dramatically decrease power consumption in these homes.
  • Unsuitable HVAC Units – As technology progresses, the tools we use can do more while spending less energy. Homes with radiant barriers use less energy on cooling, meaning that some homeowners are able to switch to smaller air conditioning units. These units break down less often and require less energy to provide the same cooling benefits.
  • No Trees Around Home – As mentioned before, homes that receive the most sunlight throughout the course of a year tend to be the hottest. A home without trees to provide shade will save more by installing radiant barriers.

All homes should meet the recommended R-value guidelines for insulation based on their region. Because heating bills tend to be higher than cooling costs, a poorly insulated home can siphon away your money even in hotter climates. 

Remember that insulation slows heat transfer—even in the summer months, insulation paired with air conditioning works in your favor.

Do Insulation and Radiant Barriers Become Less Effective Over Time?

Properly installed insulation tends to last anywhere around 80 to 100 years. Radiant barriers last even longer. While insulation material such as polystyrene and polyurethane tend to become slightly less efficient over time, the age of your insulation is probably not responsible for high costs (barring homes made before 1940). 

More than likely, your insulation was never sufficient in the first place.

Heating and cooling account for 50%-70% of any home’s energy bills. For homes ill-equipped for the elements, these costs can be even higher. While older homes are most often the culprits for unnecessary energy expenditure, most homes built today still do not meet the optimal requirements for insulation and radiant barrier protection.

Insulation and Radiant Barrier Installation Services

Without being an expert in the field, it can be difficult to know whether your home is as energy efficient as it could be. One easy way to know if you can be saving money is by entering your attic and surveying the area. If you have an HVAC unit without radiant barriers, or you can identify missing insulation coverage near the joists, you could be saving more money on your electric bill.

Breaking Down the Radiant Barrier Application Process

Written by Kevin on . Posted in Barrier Insulation, Radiant Insulation. No Comments on Breaking Down the Radiant Barrier Application Process

A lot of work goes into installing radiant barriers in your attic space—it isn’t quite as easy as just rolling out a sheet of tinfoil and hoping your cooling costs go down. 

Radiant barriers work by deflecting the sun’s rays, rather than typical thermal insulation which absorbs heat. When installing radiant barriers, thought needs to be put into the way they’re positioned. 

 Radiant barrier application can be done in several different ways, each with benefits and drawbacks. Consider the shape of your attic, whether you are using your attic floor for storage, and the climate you are in. Let’s discuss. 

Applying Radiant Barriers to Your Attic

Before installing radiant barriers in your attic, you will need to measure and cut out each sheet to meet the dimensions of the crawl space you are looking to cover. Radiant barrier application is a multi-person project—if you are applying barriers to the rafters, each sheet to be pulled so they remain somewhat taut after stapling them to the rafters. 

They don’t need to be airtight, but shouldn’t sag in between rafters either.

Some room should remain between the lowest sheet and the floor, as well as the top of the attic. This is for ventilation purposes, something that must be considered during the installation process. Each sheet should overlap the other by about an inch for maximum coverage. 

Open vents must remain uncovered for maximum air flow, and cuts in the attic radiant barrier can be made around any obstructions like water pipes that prevent forming an even surface area.

That being said, there’s more to radiant barriers than installation—you’ll need a plan designed around the way you live. Roofing specialists have different strategies depending on the geographic region they operate out of. 

Decide on your strategy before you make the first cut.

The Three Methods of Radiant Barrier Application

There’s more than one way to install radiant barriers to your attic, but each comes with perks and drawbacks. There are three common methods of radiant barrier application:

  • Open-Ridge or Staple-Up Method
  • Over-Insulation or Over-Ceiling Method
  • Hybrid Method

The basic difference between these three methods is whether radiant barriers are stapled to the rafters of the attic or if they are laid out on top of the insulation material between the joists. 

The hybrid method incorporates both.

Choosing the method that is right for you begins with checking whether you have ductwork in the attic. These are most commonly found in older homes. If you live in a home like this, you will want to attach radiant barriers to the rafters. This will keep your air conditioning from working to the point of breaking during the hottest months.

Another factor to consider is whether you are using your attic for storage purposes. If you need that extra space for odds and ends, applying radiant barriers to the floors alone will not be an effective method of keeping your home cool, and will overheat whatever you’re keeping in the attic.

With these considerations in mind, let’s look in depth at these barrier application methods, and how they can cut cooling costs in your home.

#1 Open-Ridge Method

The open-ridge type of radiant barrier installation is a method of applying heavy duty radiant barriers between the rafters, forming a protective shield that keeps your attic area cooler during the hottest months.

For people that use their attics for storage, or have any kind of ductwork and HVAC systems installed, applying this method has been shown to be an effective means of returning value on your investment.

When installing radiant barriers, make sure to clean all surfaces of the attic before placing them adjacent to the undersides of the rafters. If dust is able to accumulate on the surfaces of radiant barriers, they tend to be less effective.

For people living in hot climates like San Diego and Orange County, an open-ridge method should be considered the bare minimum for any kind of radiant barrier installation. Radiant barriers are most effective when they reflect back the rays of heat at the angle they are hitting the roof, making this method suitable for that climate.

Takeaways from the Open-Ridge Method

Open-Ridge Insulation is ideal for those living in hot regions or those who have ductwork in their attics, and tends to be the go-to method of radiant barrier application. 

Installation may require expert help to reach high or hard-to-reach areas.

Pros:

  • Keeps attic open for storage purposes
  • Best in hot, sunny climates like San Diego and Orange County where reducing cooling costs is primary concern
  • For attics with ductwork and HVAC systems, produces greatest cost savings

Cons:

  • Installation is more difficult than Over-Insulation Method
  • Covers greater surface area than laying it down, increasing initial cost
  • Requires higher-end materials so radiant barriers can remain stapled up

Over-Insulation Method

The easiest way to install radiant barriers, the over-insulation method simply involves draping radiant barriers over the joists and any existing insulation between them. This is also called the over-ceiling method, as it covers the space directly above your ceilings below the attic.

Aside from easy installation, this method is popular in houses in the Midwest as it is able to keep radiant heat inside of the home during the winter (as well as repel it during the summer months).

So, given that this method is the least labor intensive and cheapest means of installing radiant barriers, shouldn’t you be using it? 

The simplicity of this method may be alluring, but comes with many drawbacks. 

For one, attic spaces with this type of radiant barrier can’t be used for storage. Rather than reducing the heat in your attic, it will become even hotter than before. If you have any sort of ductwork or HVAC systems, they will have to work even harder to cool down your home.

Because the floor of your attic will be covered by a shiny metallic material, navigating joists when walking in an unfinished attic will be challenging. The over-insulation method radiant barrier application is not recommended for the accident prone.

Takeaways from the Over-Insulation Method

Simple to install, the over-insulation method works well in climates that require both heating and cooling throughout the year. 

It is recommended for homeowners in variable climates, but requires dusting to maintain its reflective properties throughout the year, and leaves no room for storage.

Pros:

  • Easy installation
  • Least amount of radiant barrier material required to install
  • Reduces cooling costs in summer and heating costs in winter
  • Best in climates with seasonal weather patterns, such as the Midwest

Cons:

  • Attic space cannot be used for storage
  • You will not be able to see joists—unfinished attics may be perilous to walk around in
  • Accumulation of dust will require periodic cleaning of radiant barrier surfaces
  • Not recommended in attics with ductwork and HVAC systems

Hybrid Method

The hybrid method combines the best of both worlds, covering the whole surface of your attic while providing maximum cooling efficiency. 

This means the rafters, insulation, and joists will all be covered in radiant barrier material. It is gaining popularity among homeowners as the most effective method of attic radiant barrier installation.

The best attribute of the hybrid method is that you will ensure that your home is protected against the elements in all seasons, and your attic will keep down heating and cooling costs at maximum efficiency. 

No matter what the weather throws at you, your home will remain comfortable.

Although your floor will be covered in radiant barrier material, it can still be used for storage purposes, as the attic temperature will be regulated from all sides. Some of the issues that come with using the over-insulation method will remain, but it guarantees that cooling costs will stay at their lowest possible level.

Takeaways from the Hybrid Method

The most all-encompassing form of radiant barrier protection, the hybrid method works in all seasons and conditions. It is the gold standard of attic temperature control. 

If heating your home in the winter is never an issue, this method may be excessive, but in all other cases, you can’t go wrong with this method of cooling cost reduction.

Pros:

  • Maximizes cooling efficiency from radiant barriers
  • Lowers heating and cooling costs throughout every season
  • Allows ample room for storage
  • Perfect climate for ductwork and HVAC systems

Cons:

  • Most expensive and labor intensive
  • Requires highest square footage of radiant barrier material
  • Joists will be obscured, and ground area will require periodic dusting

Should I Install Radiant Barriers Myself, or Hire Experts?

You can install radiant barriers alone, but doing so requires a great deal of planning and expertise. 

Why not leave it to people who do it for a living?

Radiant Barrier Cost: Everything You Need to Know

Written by Kevin on . Posted in Attic Insulation, Barrier Insulation. No Comments on Radiant Barrier Cost: Everything You Need to Know

If you’ve been thinking about installing radiant barriers into your attic space, you may be wondering how much it will cost. In warm, sunny climates like southern California, radiant barriers can be an excellent way to cut down on cooling costs. The Department of Energy suggests that cooling costs tend to be reduced by 5%-10%, while some sources say it can be even higher.

But are radiant barriers going to be a good value for you in the long run? 

Below, find a breakdown of the costs that you can expect when installing a radiant barrier, and the returns that you should expect to see in the long run.

Breaking Down The Cost

Depending on how you’re planning to install radiant barriers in your attic, prices for installation tend to vary from home to home. Consider these three elements when you are looking for an estimate for your attic radiant barrier installation cost:

  • Cost of materials
  • Area of surfaces you need to cover
  • Installing radiant barriers yourself vs. hiring experts

Each of these three aspects are going to factor in the kind of savings that you see in the short term and the long run. While it may be tempting to cut costs as low as possible early on, using ineffective materials or improperly installing radiant barriers can decrease returns on energy savings, and take up a lot of your time in the process.

Radiant barriers are about more than just cooling down your home—they’re an investment that you want a solid return on. Looking into the right methods to keep costs low and energy efficiency high will produce the greatest value in the long term.

Cost of Materials

Like any product, radiant barriers come in multiple varieties. The cheapest of these are single-sided barriers, which are only reflective on one side and tend to tear easily. More expensive materials have greater durability and are much easier to install, but are going to run up the tally a bit higher.

 Using higher-end radiant barrier materials is recommended, especially when you’re installing radiant barriers yourself. Cheaper materials are less likely to hold a staple, and can be less effective at blocking heat. While other kinds of insulation age and become less effective over time, you only need to install this reflective insulation material once, as it doesn’t lose efficacy over time. 

Surface Area

Radiant barrier installation is measured in square footage, and typically involves lining your entire attic space to produce energy savings. To experience a cooling cost reduction that produces the most value, radiant barriers must cover the surface area of your entire attic.

Determining the cost of materials for covering your attic with radiant barriers can be found by multiplying the total surface area of the crawl space you are looking to cover by the cost per square foot of radiant barrier material you purchase.

You may also have to factor in more than just the attic floor and ceilings when calculating this cost—many older homes have ductwork or HVAC equipment. For homes like this, the savings on cooling costs netted from installing radiant barriers can be the highest, but these should be covered as well to see the maximum benefits.

Self-Installation vs. Hiring Experts

Homeowners who decide to install radiant barriers on their own won’t have to worry about installation fees, but doing so comes with risks of their own. For radiant barriers to shine to their full potential, they must be installed properly. 

Here are a few things to consider when installing radiant barriers by yourself:

  • Wear protective equipment – Existing insulation can cause irritation to the skin and lungs when handled. Before venturing into your attic, make sure you purchase protective clothing, eye protection, and breathing protection.
  • Be careful around electrical wiring – Adding hospital costs to your budget is not recommended. When installing radiant barriers, be cautious when stapling around electrical wiring and junction boxes.
  • Don’t compress existing insulation ­– Compressing existing insulation in an attic while installing radiant barriers can decrease, rather than increase, your energy cost and bills. Because attic insulation depends on thickness for its efficacy, flattening existing insulation decreases their resistance value.
  • Watch where you step – Unfinished attics can be dangerous places, with loose nails, toxic materials, and variable headspace. Work only when temperatures are safe, and keep foot traffic to joists so you don’t fall through your ceiling.

Hiring experts to install radiant barriers may add on to your budget, but it’s a recommended expense to prevent the incursion of hidden costs like hospital bills, ceiling repair, and lowering the R-values of existing insulation.

4 Reasons Why You Might Need Air Duct Repair

Written by Kevin on . Posted in Air Duct Repair. No Comments on 4 Reasons Why You Might Need Air Duct Repair

Air ducts are often overlooked. Nevertheless, they’re some of the most important components of a home, ushering air in and out and powering cooling and heating systems. But for all the benefits proper ductwork brings, there are also many issues that can arise from ducts that have been neglected for too long. 

In fact, many issues in the home can be traced back to faulty air ducts.

This guide will first walk through the various reasons that air ducts need to be repaired or replaced. Then, we’ll go over the impacts these faulty ducts can have, as well as what you can do to fix any problems you may have with your ductwork.

Let’s start with the five most common reasons why ducts fall into disrepair:

#1: Flawed or Compromised Design

Ductwork design should prioritize efficiency. For ducts to function properly—moving as much air as possible with the least amount of loss—a few key factors are required:

  • Cover the least amount of ground possible
  • Maximize straight paths
  • Minimize turns

While qualified HVAC and other technicians understand these principles and apply them during installation, complications can arise over the lifespan of a given air duct. Construction and renovations can lead to new obstructions or changes to duct design. Or ducts may be reinstalled by amateurs rather than professionals.

In any case, faulty design is a fast track to disrepair.

#2: Leaks in the Ductwork

Even properly designed ductwork is bound to deteriorate over time, and leaks are a problem that will impact all ducts at some point in their lifespan.

As ducts channel air in and out of your home, the constant flow of air can take a toll on the ducts and their connections. Over time, the force of that air, as well as debris, can dislodge connections and corrupt sealants. These openings lead to air escaping, which causes inefficiencies and impacts the indoor air quality throughout your home.

In addition, these leaky air ducts can be caused by, or lead to suboptimal airflow.

#3: Inadequate Insulation

Leaks and kinks aren’t the only frictions to efficient airflow.

The primary function of a duct is to transport air at specific temperatures. They pump hot air in the winter and cold air in the summer. And if they’re not insulated properly, the air won’t retain its temperature efficiently. Insulation is extremely important for air ducts to function properly.

However, this crucial importance is sometimes overlooked, and ducts can be left without insulation, or insulated inadequately. In addition, even once-properly installed duct insulation may deteriorate over time due to infestation or other issues.

#4: Dirt Accumulation

Finally, an issue that impacts all air ducts is the steady accumulation of dirt.

Innumerable particles of dirt and germs exist in every square inch of air. The specific kinds differ depending on surroundings; air inside your home has its own unique characteristics, as does the air outside. Since air ducts perform the double duty of piping air both into and out of your home, they’re constantly transporting all of these various contaminants to and fro.

Over time, this dirt will accumulate, causing:

  • Damage to the ducts
  • Contamination of air inside the home
  • Inefficiencies in the air ducts’ performance

Dirt buildup is the ultimate, inevitable wear and tear. And while regular cleanings and maintenance can help, repair is also inevitable.

Now that you know how and why ducts come to need repair, it’s important to understand what kinds of negative effects these faulty ducts can have.

Impacts of Ducts in Disrepair

If any of these common problems are present in your home, your ducts are in need of some care. But while those issues are the reasons air ducts fail, the real catalyst for homeowners to do something about them are the repercussions.

Faulty air ducts can cause major problems for you, your home, and the environment.

Comfort, Health, and Safety

Comfort

One of the surest signs that your ductwork is in need of repair is ineffective or inconsistent air conditioning and heating. Since air ducts primarily have to do with cooling and heating, some of the biggest effects of faulty ductwork involve the temperature inside your home.

If your home is colder or hotter than it should be, the problem might be your air ducts.

Health

Plus, as noted above, issues with air ducts can lead to more than just inefficiencies; they can also recirculate dangerous toxins throughout your home. With poorer air quality, health issues can arise like:

  • Headaches
  • Flu-like symptoms
  • General lung problems

Safety

And, finally, faulty ducts can pose immediate safety concerns by backdrafting dangerous combustible gases (back) into your home, such as carbon monoxide.

Cost Efficiency and Sustainability

Another major impact of faulty air ducts is the financial burden of inefficiency. A cooling or heating system that’s working harder than it needs to be is a major drain on your resources.

Not only that—it’s also a major drain on the world’s resources.

For those concerned with environmental issues, faulty air ducts can throw a wrench into your plans for an eco-friendly lifestyle. By working harder and less efficiently, cooling and heating systems aren’t just running up your monthly energy bills. They’re also drawing on more natural resources, such as fossil fuels, increasing your carbon footprint.

For these reasons, and more, you may be wondering:

Do You Need Air Duct Repair?

If these have been on the to-do list for ages now… Probably.

Unless your ducts are brand new, or they’ve recently been repaired, there’s a good chance they would benefit from maintenance, if not reparative service.

If any of the five reasons listed above apply to you, then you need to service your ducts in one way or another. But, depending on your circumstances, you may not need to repair your ducts; cleaning and maintenance may do the trick. Otherwise, you might need to completely replace them.

Let’s take a look at what each procedure entails:

Maintenance

The simplest way to ensure that your air ducts perform well over time is to conduct regular maintenance. This is something you can do on your own, without professional help.

Some key practices to consider include:

  • Cleaning built-up dirt and grime
  • Screening for and addressing pest infestations
  • Checking and reinforcing all connections and sealants

Keeping up with your air ducts is the best way to preserve them over the long-term. Well-maintained ductwork requires less frequent repair and won’t need to be replaced nearly as soon.

Repair

If your ducts are in need of care beyond basic cleaning and maintenance, you should call in professional help. Trained technicians are able to assess problems and provide solutions that address not just surface effects, but root causes.

Professional repair includes but is not limited to:

  • Targeted fixes for broken air duct pieces
  • Reinstallation of individual pieces, sections, or connections

If you know that there are problems with your air ducts, but you don’t want or need to replace your whole system, repairs are your best option. Reparative work can prolong the lifespan of your existing system, helping you get the most value out of your air ducts.

Duct Replacement

Finally, there are certain scenarios in which fixing one or more individual pieces of equipment won’t solve the underlying issues. If there are deep-seated issues with your air ducts, such as problems with their initial design, there is only so much repair work can do.

Sometimes, what you need is a complete removal and replacement. This is the most involved solution, encompassing:

  • Analysis of existing ducts and space
  • Planning for new air duct installation
  • Removal of ductwork
  • New air duct installation

For this complicated process, you need professionals you can count on.

Do You Need Your Air Duct Replaced?

Written by Kevin on . Posted in Air Duct Repair. No Comments on Do You Need Your Air Duct Replaced?

It depends. If you haven’t been actively maintaining them, then chances are you need some sort of work done on your air ducts. If they’ve been neglected for too long, they should probably be replaced—or at least repaired.

This guide will walk through the most common tell-tale signs that you need an air duct replacement. Then, we’ll go over what repair, replacement, and maintenance entails.

Let’s get started!

Signs You Might Need a New Air Duct

Although air ducts play an important role in your home, they often take a backseat to other maintenance and repair concerns. But faulty ducts have negative impacts that are hard to miss.

Here are the most common signs that you need air duct repair or replacement:

#1 Hot Spots, Cold Zones

Have you noticed uneven temperatures across different rooms in your home?

This is one of the first signs that there may be something wrong with your air ducts. If a room is not becoming as cool or as warm as it should be, there is likely a problem with airflow in your existing ducts. 

When air is not getting to where it needs to be, or is coming in unevenly, you can experience differences in temperature even within a given room.

#2 Poor Indoor Air Quality

Besides issues with temperature, there are other climate factors that indicate you may need to repair or replace your existing air ducts.

The following are all potential indicators of duct-related problems:

  • Respiratory issues, like sneezing or difficulty breathing
  • Excess dust, pollen, and other airborne particles
  • Potentially dangerous mold and mildew

If you notice these or other declines in air quality throughout your home, it may be time to call in a professional.

#3 Escalating Energy and Utility Bills

If you notice an upward spike in your energy and utility bills, you might be dealing with a duct problem.

Specifically, damaged air ducts can drain resources by working harder than they should. Duct leaks and blockages cause them to pull and push more air than necessary to reach a desired temperature. That inefficiency and extra work then translates into extra dollars spent on electricity.

#4 Visibly Damaged Ductwork

Besides the more insidious issues detailed above, some of the surest signs you need duct repair or replacement are visual.

If you see any of the following, call a professional:

  • Rips or tears
  • Gaps and openings
  • Crushed portions of ducts
  • Kinks and twists in the ductwork

These are the most obvious signs. But it’s important to know that any physical defects you see are likely directly responsible for some of the other issues noted above.

If you’re asking do I need air duct replacement?, you’re likely dealing with one or more of these issues already. And if that’s the case, you shouldn’t wait to repair or replace your ducts.

Repair, Replacement, and Maintenance

Air ducts are unsung heroes. When working properly, they’re the reason that you enjoy comfortable temperatures and clean air throughout your home.

Out of the spotlight, they also get neglected over time.

All of the issues above are normal, and they will eventually impact all air ducts over time. However, that doesn’t mean you shouldn’t address them when they crop up. 

Repair and Replacement

Some of the issues detailed above are due to relatively small problems that can be remedied with repair. Others necessitate a full-scale removal and replacement.

In either case, the process is nearly identical:

  • Thorough cleaning and in-depth inspection to identify all problem areas
  • Removal of any problematic pieces or sections of ductwork
  • Replacement of all removed or damaged pieces

The difference between repair and replacement is one of scale.

If it’s just one particular piece of otherwise perfect ductwork that’s giving you trouble, there’s no need to replace the whole system. Conversely, if the entire duct system has been compromised, your best bet may be starting from scratch.

Maintenance

Once your air ducts have been repaired or replaced, it’s imperative to engage in regular maintenance to prolong their lifespan—and forestall further repair work.

That regular maintenance should comprise:

  • Cleaning out debris
  • Installing adequate insulation
  • Checking and reinforcing joints and connections

These procedures can push back the eventual repair or replacement work all ducts will eventually need. But when it is time for that work to be done, you know who to call.

Most Common Radiant Barrier Problems

Written by Kevin on . Posted in Barrier Insulation, Radiant Insulation. No Comments on Most Common Radiant Barrier Problems

A Radiant barrier is one of the best and most innovative ways to take control of the temperature in your home. Taking advantage of conduction, convection, and radiation, radiant barriers enable you to significantly reduce the transfer of heat both coming into and out of your house.

It’s such a powerful and useful technology, even NASA uses it on its spacecraft.

However, there are certain issues and complications that can arise with a radiant barrier. There are vulnerabilities inherent to the technology that can lead to issues over time. There are also certain problems that can arise from the environment or manner in which it’s installed.

Let’s take a look at what these problems are, along with solutions and preventative methods.

Problems Inherent to Radiant Barriers

Radiant barriers are on the cutting edge of insulation technology. However, there are still some potential fault lines inherent to them. As with any technology, there are important vulnerabilities that you need to be aware of.

Knowing the ways that radiant barriers can potentially go wrong is the best way to prevent any avoidable mishaps. It’s also the best way to treat and reverse corruption, when possible.

For any issues you’re experiencing, professional help is always the best answer. Nevertheless, it never hurts to know what issues to look for.

Dust Problems with Radiant Barriers

Simply put, the biggest possible problem with any kind of radiant barrier is dust.

To understand why dust creates issues for all kinds of radiant barriers, it’s important to understand how they work:

  • Radiation transfers heat directly outward from an energy source
  • That heat absorbs into any materials that it can penetrate
  • Reflective surfaces are impenetrable, so the heat bounces off
  • Contaminants like dust, however, remove this property of reflection
  • A surface coated in dust will absorb rather than repel heat

The effectiveness of radiant barriers depends entirely upon the reflective properties of the metals used. Anything that compromises reflectivity will ultimately compromise the overall utility of the barrier. So, dust accumulation will always negatively impact reflectivity.

To ensure that your radiant barrier is protected from its nemesis—dust—you need to have proper ventilation. Make sure that vents are unobstructed and air isn’t still.

Also, be sure to inspect your radiant barriers from time to time and spot-clean if necessary.

Radiant Barrier Moisture Problems

The other main issue that can impact the performance of any radiant barrier is moisture.

In colder weather, radiant barriers can sometimes develop condensation. This issue is most prevalent in climates where the temperature regularly falls below zero degrees Fahrenheit. However, it’s a potential issue anywhere that freezing temperatures are a possibility.

When radiant barriers develop moisture problems, they can impact the efficiency of heat repellency. In addition, unchecked moisture can drop down onto other surfaces in the attic, causing water damage and mold.

In order to prevent moisture issues, it’s imperative to use perforated radiant barriers. Also, regular inspection can help you identify and patch up moisture risks, like leaks from the ceiling.

Problems with Radiant Barrier Setup

Not every problem is related to the radiant barrier itself.

In addition to problems inherent to radiant barriers, there are also common issues that involve the environment and manner in which they’re installed. These issues can be the underlying causes for faulty radiant barriers, or they can be compounding effects that these barriers can have on your home. Whether cause or effect, they can be quite serious.

And, in either case, as with inherent vulnerabilities, it’s important to understand these potential issues to know what to do to prevent them or treat them as they arise.

Let’s discuss.

#1 Attic Ventilation Problems

Radiant barriers only work properly in an attic that’s ventilated properly.

Proper attic ventilation ensures that:

  • Reflected heat circulates
  • Dust can’t build up over time
  • Dangerous contaminants don’t develop

Without proper ventilation, a thermos effect will be created, and the radiant barrier can produce the opposite of its intended effect, increasing the temperature in your attic space.

In order for the reflected heat to dissipate, there needs to be air circulation that carries hot air around instead of letting it sit still. That still air is also a main factor in dust buildup. Proper attic insulation, ventilation, and radiant barrier installation can all be more effective together.

Note: As aforementioned, dust is the absolute biggest threat to your radiant barrier.

#2 Problems with Roof Temperature

Radiant barriers work by reflecting heat that would otherwise permeate into your home. In some cases, that heat can reflect back into your roof’s surface, increasing its temperature.

In many homes, radiant barrier application is done directly to the underside of a roof for an efficient and clean installation. However, it can lead to radiant barriers increasing the temperature of the roof. While roof temperature is not necessarily important, excessive heat can deteriorate the roof surface, decreasing its lifespan and creating other potential problems, like leaks.

Ventilation can resolve this issue.

Benefits of Proper Radiant Barrier Installation

Problems aside, a properly functioning radiant barrier offers incredible value. They’re a low-cost solution that complements the benefits of other home and attic insulation throughout your home.

By installing, you ensure two primary attic radiant barrier benefits:

  • Control over the temperature in your home
  • Savings in energy consumption

Radiant barriers are prone to certain issues, but no technology is immune to deterioration over time, user error, or environmental stresses. The benefits of radiant barriers far outweigh the potential costs that these issues can cause.

#1 Comfort Year – Round

Radiant barriers are designed to help you control the temperature in your home.

Their primary function is keeping heat from penetrating into your home and raising temperatures in your attic space. Without protection like radiant barriers, direct sunlight can heat up a space extremely quickly rather than using the reflective insulation to bounce off of.

Sunlight enters your home directly through transparent openings like windows. But it also enters your home indirectly through seemingly impermeable surfaces, like your roof and walls.

Heat is transferred in three main ways:

  • Conduction – Heat will travel from a hotter portion of a given material to a colder portion of it. When sunlight strikes the rooftop surface, it transfers inward.
  • Convection – As a gas or liquid substance heats up, it loses density and begins to rise. Thus, hot air in the home will rise upward toward the attic.
  • Radiation – As noted above, heat radiates directly outward from a heat source. It travels in a straight line, heating up substances that absorb its energy along the way.

By controlling for the third type of transfer, radiant barriers block heat from entering  and regulate the heat flow in the home. Other kinds of insulation work differently, aiming to slow down the first two methods of heat transfer. In practice, this means that radiant barriers work in a drastically different way from other insulation.

In fact, radiant barriers work better the hotter it is!

They also complement and improve the efficiency of all other insulation.

Finally, radiant barriers don’t just keep heat out; they also keep it in. In a cold climate, radiant barriers stop the heat from escaping, instead redirecting it to other portions of the house. This ensures uniform comfort throughout the house.

It’s also extremely efficient.

#2 Cost Efficiency

If your attic is cooler, your entire home will be cooler.

By reducing the temperature in your attic and anywhere else it’s installed, radiant barriers help you cut down on expensive cooling measures, like air conditioning. Using less air conditioning is a fast track to energy savings.

But not only do radiant barriers enable you to use less air conditioning—maximizing energy savings in the short term—they also help with long-term maintenance costs.

High temperatures cause wear and tear on cooling systems by making them work harder and longer. But they also tax these systems by forcing additional cool air through your ductwork. This extra cool air in turn leads to the accumulation of debris, which shortens the lifespan of your air ducts.

Plus, as noted above, radiant barriers also optimize your heating in a cold climate. This means that you don’t just reap the benefit of greater control all year round; your energy bills will also be lower throughout the year.

So, while it lowers attic temperatures, regulate the heat flow in the home, and increases energy efficiency, taking care of your radiant barrier is important to carry out this job. That is, as long as your radiant barriers are functioning properly, you can continue reaping the benefits.

What is a Radiant Barrier?

Written by Kevin on . Posted in Attic Insulation, Barrier Insulation. No Comments on What is a Radiant Barrier?

Radiant barrier is an innovative insulation technology. Unlike many other building materials that make up a home, radiant barriers also have a place in outer space, as NASA has used radiant barrier technology since the Apollo program.

In your home, it has the same function as it does on NASA spacecraft.

Like other forms of insulation, it’s designed to regulate attic temperature. The specific way it works sets it apart, though—the radiant barrier’s main function is to prevent heat flow from entering or escaping a given space.

Let’s go over what types of radiant barriers there are and what benefits they can provide.

Types of Radiant Barriers

There are two main kinds of radiant barrier insulation. While there is much variety within them, virtually all radiant barriers fall into one of two categories:

  • Sheet barriers
  • Spray on barriers

Each type has its own particular uses and drawbacks, but they both accomplish the same function. Let’s start with the more common of the two:

Sheet Barriers

The original and most basic medium of radiant barrier technology comes in the form of highly reflective, metallic surfaces. Most often, the metal that provides this reflectivity is aluminum foil. Per the US Department of Energy, this foil is applied directly to substrate materials, such as:

  • Plastic films
  • Oriented strand board
  • Cardboard or kraft paper
  • Air infiltration barrier material

While sheet or foil radiant barriers are among the most common, they aren’t the only way to reap the benefits of reflectivity.

Spray On Barriers

In addition to sheets of foil, radiant barriers can also be produced via spray on application.

The spray is a paint-like mixture containing flakes of the same kinds of metal that make up a sheet barrier. A technician can spray this material directly onto the underside of roof sheathing, or other surfaces in the attic space and throughout the house.

Compared to sheet barriers, spray on solutions can offer significantly more flexibility and ease of application. Spraying directly onto surfaces enables even an amateur to install a radiant barrier. However, the trade off is that they don’t offer the same level of reflectivity.

Thus, they’re not as efficient in their ability to block radiant heat.

Benefits of Radiant Barrier Insulation

The main function of any kind of radiant barrier you choose is to regulate the temperature inside your home. Radiant barriers are most commonly installed in attics, but the benefits they impart can be felt all throughout the home—and in your wallet.

Working in conjunction with other elements of your home design, radiant barriers maximize the efficiency and potency of your control over your home environment.

Let’s discuss.

Heat Reduction

How do radiant barriers work? By manipulating the laws of physics to work in your advantage. 

Per the US Department of Energy, radiant barriers take advantage of three properties in particular:

  • Conduction – Heat travels from a hotter location within one material to a colder spot within that same material.
  • Convection – Liquids or gases rise upward as they heat up and become less dense.

As such, radiant barriers are some of the most efficient insulation solutions available.

Energy Efficiency

Radiant barriers reduce the amount of money spent on cooling measures. 

In hot weather conditions, the majority of heat entering your home comes from exposure to sunlight and the hot air outside. A radiant barrier repels that heat, reducing temperatures in your attic (and elsewhere) dramatically.

And, a unique property of radiant barriers is that they work better under more intense circumstances. The hotter it gets, the better the reflective properties work.

Plus, radiant barriers can also help to lower costs spent on heating your home during winter.

By the same mechanisms that keep heat out, radiant barriers can prevent heat flow from escaping. That way, hot air circulates and permeates colder areas of your home, and your heaters won’t work as hard as they have to when too much heat is escaping.

A Guide to Home and Attic Insulation Installation

Written by Kevin on . Posted in Attic Insulation. No Comments on A Guide to Home and Attic Insulation Installation

Although it is rarely thought of and seldom seen, the insulation in your home and attic is incredibly important. If your attic insulation is properly installed and in good shape, your home will be more energy-efficient. You’ll also rest assured that you don’t have contaminated insulation that can affect the health of your home.

Unfortunately, many homeowners overlook their existing insulation and fail to include it in regular maintenance efforts. In order to keep your home insulation as energy-efficient as possible, it is important to have your attic cleaned and maintained on a regular basis, and your insulation removed and replaced when needed. Installing insulation is not as easy as it sounds, unless you have prior experience as an insulation installer or contractor. 

The process of attic insulation installation is complex and poses dangers for the unwary or inexperienced homeowner. This article will outline the main steps that attic insulation professionals at Attic Construction take when they are installing new insulation. We’ll explore some of the top signs that you need new insulation, and break down the process from identifying a problem to installing an effective solution. These steps will reinforce the importance of working with an experienced insulation contractor to remedy any problems with your attic insulation.

Signs You Need New Insulation

If you haven’t had your attic cleaned out and inspected recently, it’s time to address that oversight. Though you may not go into your attic very often, the insulation in your attic provides an important thermal barrier to the transfer of heat. Whether you have fiberglass insulation, foam insulation, rockwool insulation, or another type of insulation material, ensuring that you have an adequate level of insulation and that the insulation is in good condition is something that should be done on a regular basis.

From the outset, understand that the easiest and most effective way to understand whether you need to install new attic insulation is to schedule an inspection with Attic Construction. However, if you haven’t scheduled an inspection and are curious about key signs that you may need new insulation, here are a few:

 

  • Scratching Sounds or Bad Smells – If you’ve heard scratching in your ceiling or walls, chances are that you have rodents in your attic. If those rodents are nesting in your insulation or belongings you’ve stored up there, you will almost certainly need to schedule an inspection to determine the next steps to prevent them from having attic access.
  • Rising Energy Costs – If you’ve noticed your energy costs going up, it may be that your insulation is no longer working optimally. There are a variety of reasons for this, including moisture damage from a leaky roof, a rodent infestation, or it may simply just be old and need to be updated. Regardless, if your utility costs are rising and you aren’t sure why, it may be time to schedule an attic inspection.

 

Although it may be tempting to try to determine whether you have an adequate level of insulation and whether it is in good condition, you are probably better off leaving it to the contractor or insulation installer.

Insulating your attic is more complicated than it might seem, and it usually isn’t possible to simply glance at your insulation and determine whether it is adequate or sufficient. The required level of insulation will depend on the type of insulation used, what material it is made from, and many other factors (like proper insulation installation) that may influence the final level of insulation used. 

Attic Insulation Process

If you find that you need new insulation services, you might be wondering how to install insulation in attic space.Starting with a broad overview, the attic will need to be cleaned up and any old insulation will need to be removed. Any existing gaps that allow air leaks to pass from the conditioned part of the house to the unconditioned part will need to be filled. If a rodent infestation occurred, the attic may need to be decontaminated and rodent-proofed. Once any existing damage has been repaired the new insulation can be installed.

Now that you have a good sense of the contours of the insulation installation process, let’s break each step down in a bit more detail.

Prepping, Cleaning, and Insulation Removal

The first step in the installation process is to prepare the attic for new insulation. To do this, any old insulation must be removed along with any debris that is present. The first step in this is to ensure that any contaminants that are in the attic aren’t spread to the rest of the house during the removal process. Most often this means that the surfaces in the rooms around the attic entry are covered with thick plastic sheeting. Once that is done, any items currently being stored in the attic can be safely removed from the attic and temporarily stored elsewhere.

With the attic cleared of any obstructions, it’s time to clean up the old existing insulation. This is done with powerful specialized vacuums for blown-in insulation, or by rolling up batting insulation and placing it into specialized bags for contaminated material. Any rodent infestation will also be cleaned up at this time, and if there are signs that rodents were present it’s a good idea to have the space decontaminated.

Insulation Installation & Insulation Types

Once the old insulation has been removed and the attic floor has been cleaned, it’s time to install the new insulation. The type of insulation that is installed and how much of it you need will vary. The professional guiding you through the process will outline their recommendations, and what the advantages and disadvantages of each option are.

There are two different main types of insulation: batt insulation or roll insulation and loose-fill insulation. These have different installation methods but follow the same general principle. The idea is to install a sufficient level of insulation to not only meet the legal requirements for the State of California but also to ensure that the insulation will effectively reduce the transfer of heat from the conditioned areas of the house to the unconditioned areas of the house.

Batt or roll insulation are precut rolls of insulation that are installed between the joists of the attic. You’ve probably seen this type of insulation before and may have even worked with it during a home improvement project. Installation with this type of insulation may seem straightforward, but it can be tricky to achieve sufficient coverage given the physical characteristics of this type of insulation.

Loose-fill insulation is also known as blown-in insulation because it is installed using a specialized blower system. Using a long tube the insulation is literally blown into the spaces in the attic until a sufficient level of coverage has been installed. Blown-in insulation is great for achieving adequate coverage in hard-to-reach spaces without leaving any gaps. 

Common Insulation Materials

  • Cellulose– Made from recycled paper and naturally absorbs and retains moisture. This insulation material is treated for fire resistance and insect protection and packed very tightly to resist airflow. 
  • Fiberglass– Made from recycled glass and sand, fiberglass is a renewable resource that is naturally fire-resistant and non-combustible. Unlike cellulose, fiberglass does not absorb moisture.
  • Rockwool or Mineral Wool– Made from minerals such as basalt, diabase, and blast furnace slag. The materials are naturally fire-resistant, non-combustible, and also thermally effective. It also does not retain or absorb moisture.

Insulation Methods 

Installing insulation is not an easy job without professional consultation. The most common insulation methods used are:

  • Faced Insulation– Installed in exterior walls, basements, and attic ceiling, faced insulation is installed by tight pressing the product into the wall cavity. This method is useful to provide a vapor barrier, preventing the establishment of mold or mildew in your home. 
  • Unfaced Insulation– Unlike faced insulation, unfaced insulation lacks a vapor retarder, so it is best used for interior wall application and in rooms with less exterior exposure (living rooms, dining rooms, offices). 
  • Spray Foam Insulation– Just as it sounds, this is a foaming insulation method that insulates and provides an air barrier where applied. The foam is sprayed to fill the wall cavity and can be used for both interior and exterior applications. 

Advantages of Professional Insulation Installation

If you’re the type of person to tackle a home improvement project on your own, you may want to reconsider when it comes to installing your own insulation. Here are some of the top reasons why you should consider a professional insulation company like Attic Construction to provide your home proper insulation service to remove and replace your current insulation.

Safety

Safety is an important concern when it comes to removing old insulation and installing new insulation. Working in attics is difficult. They are tight spaces with precarious footing, and high off the ground. A careless step or a lapse in concentration can result in a disastrous fall.

Falling isn’t the only danger associated with attic insulation installation. Before you install new insulation you’ll have to remove the old insulation. That means dealing with insulation that is old, dusty, and potentially contaminated with rodent urine and feces. 

Due to these risks, our staff uses personal protective equipment that minimizes their exposure to contaminants contained in or from the old insulation. All old insulation is removed in thick, sealed bags and disposed of properly to ensure that contaminants aren’t spread. Our top tip for attic insulation installation is to work with professionals to reduce the risk of contracting or spreading dangerous contaminants. 

Better Efficiency

One of the most important reasons to replace your insulation is to improve the energy efficiency of your home. As a primary barrier to the transfer of heat, the insulation in your attic or roof deck helps keep your home cooler during the summer and warmer during the winter. 

With properly installed attic insulation, your HVAC system won’t have to work as hard to keep your home the temperature you want it to be. This not only means that you’ll be more comfortable, but that your energy costs will be lower. 

In order for you to reap all of the benefits associated with new insulation, it needs to be installed correctly. Attic insulation professionals ensure that you’re using the right type of insulation for your needs, the correct amount to ensure optimal energy efficiency, and that you have adequate coverage of your attic space.

Closing Thoughts

Installing attic insulation requires first preparing the surfaces around the attic entry to ensure that any contaminants in the attic aren’t spread throughout the home. Next, any stored belongings or debris in the attic are removed and stored in a safe location that is out of the way. Old insulation is removed and the attic space is cleaned out. If a rodent infestation has occurred it’s a good idea to decontaminate and rodent-proof the space before installing any new insulation.

Once the old insulation has been removed and the attic is cleaned, the installation of the new insulation can begin. Typically this is done either by placing roll or batt insulation in between the ceiling joists or by using a blower to blow loose-fill insulation in between the joists. The goal is to achieve a sufficient level of coverage to create a radiant barrier against the transfer of heat.

Attics aren’t the only part of the home that may require insulation! Home insulation can encapsulate everything from the attic, the floor, to the wall. It’s quite common for people to take care of wall insulation along with their attic to ensure proper insulation throughout the home.
