How to Insulate a Crawl Space

Written by Kevin on . Posted in Attic Insulation. No Comments on How to Insulate a Crawl Space

When homes are built, the type of foundation can make a big difference. While many homes are built with a basement or on concrete slabs, crawl spaces are common for homes built on a slope, or where there’s a risk of flooding. Crawl spaces are increasingly common on new constructions throughout the US. In fact, nearly 20% of new homes are built using a crawl space. 

Your home’s crawl space creates a barrier between the ground and the floor of your home and can prevent flood water from entering your living space and reduce the risk of termite infestation. It also provides easy access to your plumbing, gas connections, wiring, and ventilation so service technicians can make repairs without digging.  

However, one drawback of the crawl space is the possibility to let hot or cold air in and out of your home, which can lead to excess energy use and uneven temperatures throughout your home. It can also allow moisture buildup to create mold and mildew and lead to rot in your support beams, and in many cases the moisture buildup can penetrate your floor, causing mold and mildew on carpets and rugs. Luckily, these issues can be controlled through ventilation, air sealing, and most importantly, proper insulation. 

If you have cold floors in the winter, or you’re dealing with high energy bills each month, it’s time to consider adding insulation to your crawl space. So how do you approach this project, and is it worth the time and investment?

Benefits of crawl space insulation

Proper insulation in your crawl space, combined with air sealing and insulation throughout your home, can help keep your house more comfortable throughout the year by preventing hot or cold air from entering and exiting your home. It can also help you avoid moisture buildup that can compromise the structural integrity of your home and bring mold and mildew problems along with it. 

When your home is well insulated, you can go longer in the fall and spring without turning on your heater or air conditioner, and help your HVAC system work more efficiently when it is time to turn it on for the season. This can reduce wear and tear on your heating and cooling equipment, and in turn save you money on your monthly bills and maintenance costs for your system. 

A well sealed, insulated, and ventilated home also can help improve your indoor air quality by keeping allergens and other contaminants out of your home. Additionally, by making your home airtight you can reduce entry points for rodents and other pests, which can save you money on exterminators and repairs, as well as help you avoid diseases brought into your home by infestations. Insulation in the crawlspace can also protect your pipes from freezing in the winter, which can save you thousands of dollars on plumbing repairs. 

The pitfalls of DIY

While you can insulate your crawl space on your own, there are plenty of safety concerns to consider. Handling damaged insulation can irritate your skin, eyes, and lungs. You may also expose yourself to mold or bacteria left by pests. Additionally, the type of insulation material you use and the spaces you install it depends on a lot of factors, including the type of existing insulation that’s in place and whether or not you have a ventilated crawl space.

If you see evidence of water damage, broken insulation, or rodent infestation, the safest thing to do is hire a professional. They have the safety equipment and experience to clean out your crawl space and install adequate insulation. An expert can also help you rodent-proof the space to prevent infestations and help you decontaminate areas where rodents have made nests.  

A professional can help you determine the best materials for the job, including the proper R-value you need to use, and ensure your insulation is safe from moisture damage. If you’re not sure about the benefits of using rigid foam vs fiberglass batt insulation, you should consult an expert before you wind up wasting money on the wrong materials. 

Any time you perform work on your home without hiring a professional, you run the risk of missing out on benefits from your home warranty or insurance policy if you ever need to file a claim. Improper air sealing or insulation installation can have a negative impact on your home’s ventilation, increasing your home’s risk for water damage. It can also create a fire hazard if insulation is installed too close to electrical wiring. 

In the long run, hiring a professional can help you keep your free time open and ensure the job is done properly without wasting any materials or accidentally injuring yourself, especially when you are working in tight spaces like the crawl space. Contractors also will have comprehensive insurance coverage that will take care of accidental damage. 

So what does the job entail, exactly? There are two common approaches, depending on what type of crawl space you have. 

Insulating a vented crawl space

If you have a vented crawl space, you can simply install rolled fiberglass directly on the subfloor and between the floor joists. The insulation should be fully secured with a mechanical fastener, and you should be sure to seal off all the seams. Once the insulation is installed, you should add a vapor barrier over the insulation to protect it from water damage. 

Before you install underfloor insulation, it’s crucial to identify any air leaks and seal them using caulk or another appropriate sealant, depending on the size of the cracks. Air leaks are commonly found anywhere pipes or wires penetrate the floor. You can use weather stripping on hatches that provide access to the crawlspace within the house to prevent air leaks. 

Some homes use the crawlspace for air ducts to deliver conditioned air throughout the house. You should be very careful not to damage the air ducts, and consider adding insulation to them as well if they don’t have any. 

Ventilated crawl spaces were the standard for many years, but newer homes are more likely to close off the area under the home. While vented crawl spaces offer certain advantages, especially in areas prone to flooding, it’s worth consulting a professional and considering whether you should seal your crawl space vents and convert to an unvented, or encapsulated, crawl space. 

Insulating an unvented crawl space 

An unventilated crawl space should be treated as part of the conditioned space, and you should insulate the walls rather than the subfloor. In many cases, this will require less insulation. 

You should check all the exterior walls for air leaks and seal them off using caulk or foam sealant as you work.

With an unventilated crawl space, you should also consider adding a termite barrier that covers the areas between the joists and across the foundation wall. You should also add a moisture barrier to the dirt or concrete floor beneath your crawlspace to prevent condensation from creating water problems.

Unvented crawl spaces can offer any advantages for home homeowners, but they aren’t always the best option for your home. Unvented crawl spaces can reduce your risk of termites and other pests, and they are often better at controlling humidity and excessive moisture buildup. They can also prevent outdoor air, and all the allergens and other contaminants that come along with them, from entering your home, and can help keep your floors warmer in the winter. 

How Attic Construction can help

Signs You Need Crawl Space Cleaning

Written by Kevin on . Posted in Attic Cleanup. No Comments on Signs You Need Crawl Space Cleaning

If you’re like most homeowners, you’re not spending much time under your house inspecting the underside of your home. However, issues in your crawl space can impact your monthly utility bills, reduce your indoor air quality, and prevent your home from maintaining a cozy temperature. 

There are many issues that can develop in your crawl space. Ideally, you should perform a visual inspection of your crawl space twice a year, and contact a professional if you find any issues. There are plenty of things you can keep an eye out for that can warn you when it’s time for a crawl space decontamination. Here’s what to watch for:

Moisture build up 

If your crawl space stays wet, it won’t be long before you deal with mold spores and mildew contaminating your air. Moisture can also cause your wooden support beams to rot and destroy your insulation, which will make heating and cooling your home more expensive. 

A vented crawl space is often more prone to moisture buildup than an unvented crawl space. Worse, if there is standing water, you may have to deal with heavy mosquito activity coming from the floors of your house. Hiring a professional for crawl space cleaning present mosquitoes from entering your home, as well as address issues causing moisture build up.

High humidity in your home

Having moist air in your home ican be another sign of standing water or moisture build up in your crawl space. Having humid air indoors comes with its own set of problems, as well. Humid air is more difficult to heat and cool because water resists temperature change. It can also trap more allergens and pollutants in the air, and causes your lungs to work harder to breath, which can be especially worrisome for people with asthma. 

Rodents or other pest infestation

Your home can be a cozy space with plenty of food and shelter for all kinds of critters. If you see signs of rodent activity, such as feces, claw marks, and chewed wires, you need more than an exterminator to help. Rodents and insects carry disease that are left behind in feces and urine. When it’s disturbed, bacteria and viruses can be released into the air. As much as 50% of the air you breath in your home rises from your crawl space, so these areas should be professionally decontaminated to ensure your family stays safe. 

Mold or mildew odor 

While mold growth doesn’t always have a smell, much of it has a distinct musty odor. Mildew has a signature odor reminiscent of dirty socks or rotting wood. If there are persistent smells in certain areas of your house, you should have your crawl space and attic inspected. There may be leaks or standing water, and the longer these issues remain, the more damage they can do. 

Plumbing issues 

If you recently had a burst pipe, or there’s a water leak under your house, you should have your crawl space professionally inspected. Once your plumbing issue is resolved, an insulation specialist can help you insulate your crawl space to keep your pipes from freezing in the future, and help you save money on your energy bills. 

Cold floors and uneven temperatures

If you notice drafts, cold floors, or uneven heating and cooling throughout your home, you likely need insulation and air sealing services. These can address air leaks and temperature loss through the floors, attic, and walls. Not only can these services keep your home more comfortable, but they can prevent moisture issues and infestations. A professional installation installer can determine where you need more insulation and the best kind for each area.

Dirty crawl space

Damaged insulation, rotting wood, decaying materials, and debris are signs that your crawl space needs professional attention.  However, any dirt build up can damage your insulation, causing it to break down well before it’s meant to. If your crawl space is getting messy, it’s time to hire a professional. 

Benefits of a crawl space cleanout 

Clearing out your crawl space offers plenty of money saving benefits to your home, including:

  • Improved indoor air quality – Crawl space cleaning can improve your indoor air quality by removing contaminants that can be spread through the air coming through your floor, as well as sealing the space and preventing outdoor air from infiltrating your conditioned space.
  • Lower utility bills – Crawl space cleaning and insulation can help your HVAC system work more efficiently so you can enjoy a more comfortable home and save money on your energy bill
  • Reduce mechanical problems in your HVAC system – the harder your air conditioner or heater has to work, the more likely you’ll run into issues with belts, blowers, and other moving parts in your system. Crawl space cleanup will help prevent short cycling and constant running that’s hard on your HVAC system. 
  • Extending the lifespan of insulation – Fiberglass insulation can last for decades with proper care, but water, rodents, and dirt can easily damage the insulation and break it down well before it’s expected lifetime. 
  • Pest protection – Attic construction specializes in protecting your home from infestations by rodents, and by air sealing your home we can prevent other pests such as termite colonies, carpenter ants, and roaches from finding an entry point. 

While many confident DIYers are gungho about saving money on home projects, there are safety considerations for working in the crawl space Hiring a professional means you won’t risk exposing yourself to the many dangerous diseases associated with infestations, including Salmonella, Lymphocytic Chorio-meningitis, and the Plague. Professionals are also qualified to handle damaged insulation, and they are used to working in tight spaces.  

What to expect from crawl space cleanup

We provide free, thorough inspections to check your home for air leaks, rodent issues, and insulation deficiencies. If we recommend a crawl space cleanup, here’s what you can expect:

  • Clean up and Decontamination services – We start by removing any scraps and debris. Next, we will decontaminate the space to remove mold, mildew, bacteria, and other disease causing pathogens. This will also address any musty or dank odors that are making your home less pleasant to live in. We utilize safe, eco-friendly cleaners that are effective as well as pet and kid friendly 
  • Crawl space insulation – Our team can help you determine whether to remove old insulation or supplement it, and help air seal your home to keep it more comfortable through every season. We can also take care to ensure damaged insulation doesn’t affect your air quality while we remove it. We can also help you decide whether to encapsulate your crawl space or vent it, and air seal and insulate the space accordingly to prevent issues that are common with either approach. 
  • Moisture control – Once your insulation is installed, we’ll use a vapor barrier to protect it from water damage and prevent moisture buildup. A vapor barrier may be installed over your insulation on the subfloor as well as on dirt floors to prevent moisture from entering through the ground.  
  • Duct maintenance – Many homes have air ducts in the crawlspace that deliver conditioned air through the home. If they are damaged or clogged, it can significantly impact your energy use, as well as cause dirt and other contaminants to blow through the air in your home. We can repair or replace damaged ducts and provide them with additional insulation as needed. 
  • Pest proofing services – We can prevent termite and rodent infestation with proper sealing and insulation to protect your home from damage and your family from disease. In some cases, we may recommend a pest control service to remove an infestation from your home before we can address the damage they have done to your crawl space or attic. 

Our team can also handle issues with wall and attic insulation, and rodent proof your attic to prevent an infestation from above. In addition to providing a more comfortable home, professional insulation and attic cleanout services can help protect your home from fire hazards and keep your HVAC system running more efficiently, which can save you money on energy bills and repairs.

What is Attic Air Sealing?

Written by Kevin on . Posted in Attic Insulation. No Comments on What is Attic Air Sealing?

Your home is built to protect you from the elements, but not all homes are created equally. As much as 30% of your energy usage is wasted on air leaks throughout your house, and the attic is one of the biggest offenders. When you have significant leaks, warm or cold air that travels through ducts in your HVAC system will get trapped in the attic, causing a spike in your energy bill. It can also affect the comfort of your home, allowing outside air to travel freely into your house and letting the conditioned air escape. Attic insulation installation and air sealing work to prevent these problems and can provide a variety of other benefits as well. 

The prospect of air-sealing attic crawl spaces on your own is daunting, but an experienced contractor can ensure you use the right materials and address all of the common concerns. Additionally, they can help you install insulation and improve ventilation for increased energy efficiency and a more comfortable home. So how do you know if you need to air seal your attic, and what does it entail? 

When to consider attic air sealing 

Air sealing attic bypasses is a process that involves finding areas where conditioned air can impact the home and sealing them off. Hiring a professional who knows how to air seal attic crawl spaces offers many benefits, including a lower utility bill, improved indoor air quality, humidity control, and improved efficiency of your HVAC system while protecting it from wear and tear. The process can also reduce your carbon footprint and make your home more eco-friendly. A well-sealed home can protect you from pest invasions by reducing entry points for insects and other small animals, as well as keep dust and dirt from blowing into your home.

While many newer homes are designed with up-to-date energy efficiency features to keep your home from leaking air, they require maintenance to reap the full benefits. On the other hand, older homes are often designed to outdated standards and lose a lot of air. If you’re not sure whether or not your attic is insulated, or if there are significant air leaks, it’s worth taking some time for an inspection. If access to your attic space is unsafe, or you notice mold or mildew, you should hire a contractor that provides complete attic air sealing services to take a closer look. They can identify problems, help you address the issue much faster than you can on your own, and ultimately determine the answer to the question of “is air sealing the attic worth it?” 

Signs you may need to consider air sealing attic space include:  

  • Noticeable drafts
  • Uneven heating and cooling throughout the home
  • High energy bill 
  • Excess dust
  • Dry air in the winter

Air sealing alone isn’t enough

Eliminating air leakage is only one step in the process of improving your home energy usage. Without insulation, it is much harder to maintain the ideal climate indoors. Insulation works by reducing the transfer of heat from one space to another, and it also can help you control moisture in your attic. 

There are a variety of insulation types, and trying to figure out the best type for your home involves careful consideration. Marketing for some insulation types leaves out many drawbacks that come along with them, such as how well their ability is to control fire or pests, and how well they stand up over the years. A professional can educate you on the advantages of different materials, such as fiberglass batts, spray foam, or cellulose insulation, and help you find the best value for your home. 

The other important factor for keeping your home comfortable is ventilation. Improving ventilation will keep your home cooler by moving warm air outside, and protect your insulation from water damage by minimizing moisture buildup. However, adding too much insulation or sealing off your attic improperly can have a negative effect on your home’s ventilation. A contractor will have the experience to add proper insulation and seal areas carefully without obstructing the airflow in the attic. They can also repair a malfunctioning ventilation system so you can protect your home and keep it comfortable. 

Insulation and ventilation should also be considered together if you want the full benefits of air sealing attic spaces and get the most out of the money you spend on the project, and the best way to do this is with expert guidance. 

Why you should hire a professional 

There are many safety issues with working in the attic, even for people with a lot of DIY experience. Simply accessing the attic and working in a limited space can be risky unless you have experience.  Older types of wiring in the attic can be a fire hazard around insulation, and a professional will know how to mitigate these issues. These same homes may have insulation that contains asbestos, which requires special care to handle. Additionally, the attic can get very hot, which puts you at risk for heatstroke if you don’t take the proper precautions.

A professional has the tools and training to get the job done safely and thoroughly, without eating into your free time. Using a professional will also ensure your home warranty and insurance covers any future issues in your attic. The team at Attic Construction is licensed, bonded, and insured, and we offer a free one-year warranty for all our work. Here are some of the steps we take as we approach your project:

Identifying and sealing attic air leaks 

Our expertise allows us to quickly identify air leaks in your attic. We will check and seal fixtures that penetrate the attic floor or ceiling, such as light fixtures, vents, chimneys, pipes, wiring, and electrical outlets. As we identify attic air leaks, we can seal them off using caulk, spray foam, or aluminum flashing as needed. We can also add weather stripping to the attic hatch. 

Inspecting the ductwork

Our team can identify damaged or leaky ductwork and repair it, as well as clear out obstructions or dirt that is reducing your HVAC system’s efficiency and affecting your indoor air quality. Our team can also repair tangled or kink ducts and help you decide whether repair or replacement is the best option for your home. Repairing your ductwork can help you keep your home cleaner and reduce allergy symptoms.

Adding insulation

Proper insulation is best left to the professionals. Our experts can evaluate the condition of your home’s current insulation and help you determine the best places to add fiberglass insulation and the best R-value for your home. We offer insulation for the attic, ductwork, exterior, and interior walls, and in the crawl space underneath your floor. We can also help you determine whether to remove existing insulation or supplement it. 

Moisture control 

There are many ways that moisture can enter your attic. If the kitchen, bathroom, or dryer is blowing humid air into your attic, this can create a mold and mildew risk. Additionally, excess water can build up when there is too much hot air in the attic in the summer. The moisture can ruin your insulation and cause wood to rot, which can compromise the structure of your home.

Installing a radiant barrier

Unlike ventilation or insulation, radiant barriers help regulate your home’s temperature by preventing hot air from getting into the attic in the first place. We can help you select and install a radiant barrier with the best reflectivity and emissivity for your particular home. 

Pest control 

Rats, mice, and other animals may try to make a home in your attic. They can chew through your attic insulation, wiring, and roof framing, causing extensive damage. Some of these animals carry diseases that can have serious health consequences. While an exterminator can take care of the problem once they’ve nested, our team can prevent them from entering your home in the first place. This can save you money on home repairs and protect your family from diseases. 

Ventilation repair 

If your ventilation system isn’t functioning properly, adding insulation and sealing the attic will exacerbate the problem. Our team will evaluate your current ventilation and make repairs to your system as needed to prevent lost air from your HVAC system and keep your attic cooler in the summer.

Is Air Sealing an Attic Worth it?

Written by Kevin on . Posted in Attic Construction. No Comments on Is Air Sealing an Attic Worth it?

Your home is meant to be a safe, comfortable space you can relax in. Unfortunately, if your HVAC system is working nonstop, you have inconsistent heating and cooling from one room to the next, or your utility bill is spiking in the middle of summer, you may consider an attic insulation installation and air sealing project to help you save money and keep your home cozy year-round. 

So is air sealing the attic worth it? The answer is yes, but only if you can also ensure your home has proper insulation and ventilation. Let’s look closer at the role these three elements play in improving your home’s energy efficiency. 

The impact of air leakage

Air leaks occur throughout your home, and they are typically found wherever two different building materials meet. Doors and windows along any exterior wall can let outside air in if they aren’t properly sealed, but even little things like electrical outlets can cause issues. 

Attic air leaks are one of the major culprits because they lead to your roof, and they can reduce your energy efficiency throughout the year. In the winter, hot air has a tendency to rise. The various fixtures that penetrate your attic floor, like lights, fans, and the attic hatch make it easy for you to literally blow money away. In the summer, the hot sun can create a scorching attic, often as hot as 140 degrees, which can make it difficult to keep your home comfortable. Has this got you wondering how to air seal attic crawl spaces? 

You can attempt to find air leaks in your home. By turning off the HVAC system and using a candle or stick of incense, look for areas where the smoke or flame starts moving erratically. This is the source of a draft. The safest and smartest option is to hire a professional to perform a blower door test. This test can determine exactly how much energy loss you’re seeing from air leakage and quickly identify these areas so they can be sealed. 

Air sealing your attic space can reduce your energy use anywhere between 30-50%, but you won’t see the full benefits of air sealing attic crawl spaces if your home lacks proper insulation and there isn’t enough ventilation to allow sufficient airflow. 

How ventilation helps 

Attic ventilation moves warm air in the summer and cold air out of your attic and reduces strain on your HVAC system. A vented attic also prevents moisture buildup caused by condensation from ruining your insulation and rotting the support beams on your roof. 

There are a lot of factors that affect ventilation, including air leaks, the type of ventilation system that’s installed, and the design of your roof. The amount of insulation you have and where it’s installed can also reduce or improve the airflow. Our attic insulation team can ensure your ventilation system is working properly to avoid issues in regard to air-sealing attic spaces. 

The role of insulation 

Air leakage can account for some of your energy efficiency, but even once the home is well sealed, the thermal exchange can still occur through the walls, floor, and ceiling, and attic space. Insulation can prevent cold air or warm air from entering through these areas, and a professional can help you evaluate your insulation in several key areas. 

Most homes rely on an HVAC duct system to deliver conditioned air throughout their home, but over time the ducts can develop leaks or get obstructed by dirt and debris, which can reduce your indoor air quality. Simply cleaning and repairing your ducts and insulating them can address around 15% of your air leakage in your home, and when you combine with addressing issues in your floors, walls, and ceiling, you can eliminate nearly half of heat loss and gain in your home. 

With proper attic insulation, you can help your home’s HVAC system operate at peak efficiency. This will lower your monthly energy bill and help prevent costly maintenance issues. Insulating the crawl space can prevent cold floors in the winter and keep your pipes from freezing, as well as reduce heat from rising through the floor. 

At Attic Construction, we can help you determine the best types of insulation for each space, and help you identify areas that don’t have insulation, or whether to remove existing insulation or supplement as it wears down. Additionally, we offer duct sealing services and can install a radiant barrier in your attic ceiling to prevent heat from entering your home from above. Plus, we can equip your home with pest prevention measures that can remove access points for rodents and insects. 

The bottom line

Attic air sealing can be a worthwhile project if you want to have a more comfortable home and lower utility bills. However, taking on the project on your own can be daunting. The team at Attic Construction has extensive experience handling insulation and other attic services so you can enjoy the full benefits without wasting time and money on common mistakes. Our offices are open 7 days a week and we are ready and waiting to schedule your free inspection. Contact us today to learn more about how we can help seal attic bypasses in your home, whether that be through fiberglass batt, spray foam, or cellulose insulation.

How to Air Seal an Attic

Written by Kevin on . Posted in Attic Insulation. No Comments on How to Air Seal an Attic

Throughout many homes, there are plenty of spaces that air can enter and exit. While tiny cracks and crevices may not seem like much, their combined effect can make a big impact on your home’s energy use. Air leakage in the average house has the cumulative effect of leaving a window open 24/7. Luckily, there are several ways to reduce outdoor air infiltration – one of which involves learning how to air seal attic crawl spaces.  

In the winter, attic insulation installation and air sealing can prevent heat loss that can save nearly a third of the energy your furnaces use. The same goes for the summer, where many homeowners have to spend big money trying to keep their space comfortable. Air sealing combined with proper insulation and adequate ventilation can save you about 15% on your monthly bills, which can translate into thousands of dollars over the course of a few years. It can also prevent pests from entering your home, provide even heating and cooling from room to room, improve your indoor air quality, and save you money on HVAC repairs. 

So, is air sealing the attic worth it? And if so, how do you approach this project? The first step is identifying air leaks around the house. 

Detecting air leaks in your home

One simple way to discover an air leak is with smoke. If you turn off the AC and any fans in the house, you can light a stick of incense and move it around common problem points and watch for places where the smoke begins to move erratically. 

These places can be around windows, doors, cracks in the walls, ceiling, or floors. In the attic, you can check around light fixtures, electrical connections, and near vents, chimneys, or other fixtures that go through the attic floor or ceiling. The attic space in your home shouldn’t have conditioned air, so places such as the attic hatch and vents that lead up through the ceiling are just important to seal off. 

Another way to spot air leaks is to look for dirty or damaged insulation. However, you should never handle insulation without proper protection for your hands, face, and eyes. Older, existing insulation may contain asbestos, but even newer types of asbestos can irritate your skin and eyes, or damage your lungs if you breathe it in. 

An experienced contractor can perform this job efficiently, and they know how to handle all types of insulation safely. They have the experience and tools, such as thermal leak detectors, to make short work of this task. They can also ensure your attic still has adequate ventilation after you seal air leaks and add insulation. This will keep warm air from overstaying its welcome in the attic and prevent costly repairs from water damage. 

How to seal air leaks

Caulk can be used to seal cracks that are smaller than a ¼” in width. You can use weather-stripping to create an air barrier in cracks and spaces around doors, windows, and the attic access. For larger holes, such as the ones around lighting fixtures, you can use spray foam insulation, but installing it properly takes experience, and it can get expensive fast if you don’t use it wisely. 

For homes with single-pane windows, the cost of replacing each one can add up quickly. A more budget-friendly approach is to use window wrap on windows and to replace them with more energy-efficient models as you can in the future. Cracks in the floor can also cause a lot of air leakage, and there are a variety of fillers you can use depending on the type of flooring you have.

Sealing air leaks in your home is a long, time-consuming process, and hiring a contractor can save you a lot of time and energy while ensuring the job is done correctly. Of course, air sealing attic spaces can only go so far when it comes to keeping conditioned air inside your home. If you have insufficient ventilation or insulation, you likely won’t see the dramatic difference in your energy bill that you’re hoping for. 

The importance of insulation

Regardless of how well you can seal off air leaks, heat transfer can still occur unless you incorporate proper insulation. The team of insulation experts at Attic Construction understands how to properly install insulation and air seal attic spaces in your home as well as identify areas that are underinsulated. We will inspect places your HVAC system uses, such as inside an exterior wall, throughout the crawl space, in the attic, and around the air ducts. Even if you have existing insulation, it may not be sufficient. 

We can help you determine when to remove damaged insulation or supplement it, and educate you on which insulation will give you the best value for your money. We can blow in fiberglass insulation into wall cavities and fiberglass batts throughout your attic space. We will also inspect your ventilation system and make any repairs to ensure it’s up to the job. Insulation in the crawl space can prevent warm or cold air from entering your house from below as well as prevent a plumbing pipe from freezing weather. 

Once we’ve ensured you have adequate insulation and ventilation throughout your home, sealed any air leaks, and made necessary repairs to your ductwork, you should notice an immediate difference. Are you ready to experience the many benefits of air sealing attic spaces?

Benefits of Air Sealing Your Attic

Written by Kevin on . Posted in Uncategorized. No Comments on Benefits of Air Sealing Your Attic

Your HVAC system can account for between 40-55% of your home’s energy consumption. The more efficiently it performs, the lower your bills and your carbon footprint will be. Unfortunately, even if you have a newer energy-saving system, you can’t get the full benefit of this system if you have significant air leakage. Outside air can travel into your home through cracks in the floor, walls, and ceiling, as well as through fixtures such as windows, doors, and even electrical outlets along an exterior wall. 

Attic air sealing prevents outside air from entering your home and ensures that your conditioned air stays within the interior walls, so you don’t have to waste energy cooling or warming your home. In fact, there are many benefits this project can offer, provided you have adequate insulation and ventilation. If you are on the fence wondering, “is air sealing the attic worth it?”, some of the benefits of air sealing attic crawl spaces include:

Consistent temperatures throughout your home

Your HVAC system is designed to distribute conditioned air throughout your home evenly, but air leaks, obstructions in your ducts, or heat gain and loss through uninsulated areas can prevent your system from distributing air evenly throughout the house.

Reducing attic air leaks and thermal transfer, as well as improving your home’s ventilation, reduces strain on your HVAC system and helps it keep the entire house comfortable. Even if you have sunny areas in your home, the improved air flow will help move cold or warm air throughout the house to reduce indoor temperature differences from one room to the next. You can further these benefits with an insulation upgrade and by installing new windows or adding window wraps to mitigate heat transfer.  

Improved indoor air quality and a cleaner home

The filters on your HVAC system are designed to clear out dust and debris from your indoor air, and depending on the filter they clear out allergens and other contaminants. Air leaks or damage in the duct system can allow these particles to enter the air. Similarly, air leaks in the rest of your house can let outside air, and all the pollen, dirt, and other things that come with it, into your house. 

Sealing your ducts and the air leaks throughout your house can reduce dust and dirt build-up and improve allergy symptoms, which can make your house a safe haven during allergy season, especially if you have asthma. 

Save energy and money with improved efficiency 

Air leaks and thermal transfer can significantly impact the heating or cooling cycle of your HVAC system. In some cases, it may cause your system to turn on and off for short periods of time, while in others it may cause your system to run constantly. This can cause mechanical issues, and it will definitely reduce the efficiency of your air conditioning and heater. Just like stopping and starting your car in traffic or driving too fast wastes fuel in your car, your HVAC system will burn excess energy when it’s not operating as intended.  

Sealing and insulating your home, as well as improving air flow will help your HVAC system operate at peak efficiency in the summer and winter and help you avoid turning it on for longer when the weather is nice outside. Because these improvements to your home can last for years, the investment pays for itself and will ultimately save you money in the long run on your utility bill and HVAC repairs. 

Moisture control 

A leak in your roof can cause significant water damage even after a single rainstorm, but roof leaks aren’t the only way moisture can get into your home. Because the difference between the indoor temperature and your attic can vary widely, water vapor in the air can form droplets throughout your attic space unless you can control it. Insulation, ventilation, and air sealing projects can prevent mold, mildew, and water damage from causing health issues and compromising the structure of your house. 

Protect your house from pest

By eliminating air leakage in your home, you also reduce entry points for pests. Animals such as termites, rats, and mice can cause extensive damage to your home, and many insects and rodents carry diseases. They can chew through wires, scratch or heat your home support beams, and destroy attic insulation. Some of them may even bite if you have close contact with them. 

Beyond improving the energy efficiency of your home, our team can help rodent-proof your attic and clean up contaminated areas in the crawl space and attic, so you aren’t exposed to harmful bacteria and viruses associated with rodent waste. As with many problems, pest prevention is always cheaper and safer than trying to clear your house of an infestation. 

Noise control 

If your neighbor wakes up early every Saturday to mow the yard, or you live by a busy road, the outside noise can be a big nuisance. Properly air sealing attic spaces, windows, doors, and so forth can help make your home a quieter, more relaxing environment, so you can sleep in late whenever your schedule allows it, as well as turn the volume up on your favorite album without worrying about a noise complaint. 

Many people blame thin walls when they can hear everything that happens in any part of the house. While adding wall insulation may help, often the problem lies in your air conditioner. Sealing and insulating your air ducts can keep things like conversations, music, or the sound of the TV from carrying room to room, so you can enjoy a little more privacy or focus better while other people in the home carry about with their business. 

When to consider attic air sealing

Many newer homes are built to better standards than older homes, and not every house has air leakage or insulation issues. However, no matter how old your home is, you should consider hiring an attic air sealing service if you have:

  • Costly energy bills
  • Noticeable drafts 
  • Certain rooms are too hot or too cold
  • Damaged or missing insulation
  • Mold or mildew in the attic 
  • Dry indoor air 

Benefits of hiring a professional 

While many people may prefer the DIY route, this is a time-consuming project to take on your own, and any mistakes can cost you money and waste your weekend. Without the proper training or tools, sealing air leaks in the attic or adding insulation can reduce your home’s ventilation, which can exasperate moisture issues. 

An expert will also understand where air leakage occurs throughout the house and can seal it with the appropriate materials. They will already know how blown insulation settles and can install the correct amount, and understand when it’s appropriate to use spray foam or fiberglass batts in different areas of your attic. 

Additionally, there are many safety concerns to consider. The attic can get extremely hot, which puts you at risk of heatstroke if you don’t take proper precautions. Damaged insulation can irritate your skin, eyes, and lungs, and some of it may contain asbestos. 

The experienced specialists at Attic Construction have the tools and training to get the job done safely and efficiently the first time. We can quickly identify where air infiltration occurs with a blower door test, evaluate the condition of existing insulation, and help you determine the correct R-value and type of insulation for different areas of your home. 

By hiring our team, you can rest assured that your home will have increased efficiency without wasting time, money, or materials on learning how to air seal attic leaks without help. Fiberglass insulation can last for up to 100 years without losing any effect, making it an investment that will pay for itself over and over again. However, things like moisture, dirt, punctures, or heavy boxes stored on top of it can damage it, and you’ll have to replace it. Our installers can ensure your insulation lasts for as long as possible through proper installation and by educating you on ways to avoid damaging it.

The bottom line

Having a comfortable home gives you a safe haven where you can relax and enjoy your free time however you see fit, and by hiring trusted professionals, an attic air sealing project can provide that any time of the year. Attic Construction operates 7 days a week, and we work with you to schedule a free consultation whenever it’s convenient to you.

What Is The Most Eco-Friendly Insulation?

Written by Kevin on . Posted in Attic Insulation. No Comments on What Is The Most Eco-Friendly Insulation?

Just about everyone knows how important recycling and driving energy-efficient cars are to reducing your environmental impact, but did you know that your home’s insulation building material could also make a big difference in decreasing your carbon footprint? 

In this article, we’ll go over how having the right amount of insulation can help decrease your home’s CO2 emissions and talk about which types are the most eco friendly insulation materials. 

How Insulation Can Help Reduce Your Environmental Impact

Having enough insulation in your home is important to reducing your energy consumption. Because insulation determines how hard your heating and cooling systems have to work to keep your home at a regular temperature, installing the right home insulation materials can reduce your carbon emissions (and your energy bill).

Homes with proper insulation are better protected against outside weather, which means they only use a fraction of the energy to keep homes at a comfortable temperature. It’s estimated that buildings in the US with good insulation slash CO2 emissions by 780 million tons per year.1 

The problem is that only one in every ten homes in the US currently has the right amount of insulation needed for this kind of energy efficiency.2

So how can you tell if your home is underinsulated?

Signs Your Home Needs New Insulation 

Here are some things to look out for to determine whether or not your home has enough insulation:

  • Drafts in the house
  • Uneven temperature from room to room
  • Cold walls and floors 
  • High energy bills 
  • Poor sound barrier

If your home shows any of these signs, it’s likely that you’re wasting energy (and money!) due to poor insulation installation, and it’s time to replace it. 

How the Insulation Material You Choose Impacts the Environment

Having enough insulation in your home is important to lowering your home’s energy consumption, but not all insulation materials are equally as eco-friendly. Some materials actually risk increasing your environmental impact. 

To explain why, let’s take a look at spray foam.  

The Environmental Downsides of Spray Foam Insulation

Spray foam rose has risen in popularity as a form of insulation in recent years because of its vapor barrier and air sealing abilities. Unfortunately, these properties come with downsides for the environment. 

Spray foam gives off a ton of greenhouse gases, which depending on its chemical makeup, can be up to 1,400 times more damaging to the environment than carbon dioxide.3 Spray foam is also often treated with a variety of harsh chemicals to help keep them from becoming flammable. These chemicals can have a negative impact both on the environment and the air quality of your home if off-gassing occurs. 

The good news is there are a number of alternative insulation options that are much better for the environment.

Eco-Friendly Insulation Material   

When it comes to looking for an environmentally friendly insulation, here are some important factors to look for:

  • Material Quality – Insulation that is environmentally friendly will be made out of recycled material and have minimal chemical treatment. 
  • R-value – Materials with a high R-value will be better able to regulate heat flow in your home and therefore better at reducing your energy consumption. 
  • Longevity – Insulation that lasts a long time can reduce overall waste as it won’t need to be replaced as often.
  • Price – When looking at sustainable insulation materials, it’s important to make sure that you pick one that fits your budget.

Here’s how some of the top eco-friendly insulation materials compare based on these metrics:

  • Fiberglass (best option)
    • Made of between 40-60% recycled glass 
    • Has an R-value of between 2.2-4.3 
    • Can last up to 100 years 
    • Made out of low-cost material
  • Cellulose 
    • Made up of between 82-85% recycled paper 
    • Has an R-value between 3.2-3.5
    • Can last up to 30 years4
    • Made out of low-cost material
  • Cotton 
    • 85% recycled fibers and 15% chemically treated plastic 
    • Has an R-value between 3.4-3.7
    • Can last up to 100 years5
    • Made out of higher-priced material
  • Mineral Wool 
    • 75% recycled building material 
    • Has an R-value between 3.7-4.2 
    • Can last up to 100 years 
    • Made out of higher-priced material 

Which Insulation Material is The Most Eco-Friendly?

While having an insulation material made out of recycled contents is important, what matters most is finding an effective but affordable insulator that will help you reduce your long-term environmental impact. 

All the insulation types listed above have different strengths, but the fiberglass insulation product is the only one that meets all the green insulation standards. If you’re interested in installing insulation, learn more about fiberglass insulation costs here.

Cellulose vs Fiberglass Insulation

Written by Kevin on . Posted in Attic Insulation. No Comments on Cellulose vs Fiberglass Insulation

Insulation is essential to help protect your home from outside weather and keep your energy bill from skyrocketing. But not all insulation materials are made equally. If you’re undergoing a new construction project, you need to know which type of insulation fits your home’s unique requirements. There are many types of wall insulation materials from insulating concrete forms to foam board, as well as many types of attic insulation, including loose fill fiberglass insulation vs foam, blown in insulation, and more. 

Each insulation type has its own set of benefits and disadvantages that affect whether or not it’ll fit well with your home. Finding the insulation material that best suits you and your family’s unique needs can make all the difference in creating a safe and comfortable home environment.

To help you figure out which insulation product is best for you, we’re going to be comparing cellulose vs fiberglass insulation. 

The Basics of Fiberglass Insulation

If you’ve seen pink, cloud-like material in attics before, this is not an industrial form of cotton candy—this is traditional fiberglass insulation. Fiberglass is one of the most popular kinds of insulation and for good reason. It’s a low-cost but effective way of regulating the temperature in your home. 

But what is fiberglass attic insulation exactly? 

Fiberglass is a material made of tiny pieces of mostly recycled material such as glass that has been melted down, combined with other materials like sand and limestone, and then woven into long strands, giving it a cotton-like appearance.

Fiberglass comes in many different forms, but the two that are most commonly used for home insulation are batts and loose-fill fiberglass.

Fiberglass Batts

Batts are made up of large rolled-up sheets of fiberglass held together by either aluminum foil or adhesive paper.1

Batts are the most commonly used form of fiberglass insulation in homes because they make installation quick and convenient. Batt insulation is designed to fit between standard-sized joists, which means all you need to do to install is to unroll it and then attach.  

One downside to this type of insulation, though, is that it’s difficult to customize these pre-made rolls to fit different shapes. This makes it hard to install in attics with pipes or other obstructions between joists. 

That’s where loose-fill fiberglass comes in. 

Loose-fill Fiberglass 

Like batts, loose-fill fiberglass is also made up of tiny fibers of recycled glass. Instead of being woven into long blankets, though, they’re cut into small pieces which are then blown into place using an insulation-blowing machine. 

Loose fill insulation allows for people who cannot get batts installed in their attic due to obstructions or other reasons to still be able to enjoy the benefits of fiberglass insulation.

Pros and Cons of Fiberglass

One of the many reasons fiberglass is a popular choice among homeowners and attic professionals alike is that there are many upsides to fiberglass and only a few downsides.

Cellulose vs Fiberglass Insulation Pros and Cons
Fiberglass Insulation Pros Fiberglass Insulation Cons
Cost effective and low-cost material Doesn’t work effectively when wet and until it has been professionally dried
Helps decrease your energy bill by 40% Improper self installation and handling can lead to health problems
Last up to 100 years in ideal conditions Loses R-value in extreme cold and temperature changes2
Lower risk of it catching fire or developing moisture-related problems Loses R-value when compressed or packed densely2
Excellent noise insulation
R-value between 2.2 and 4.3
Fiberglass batts are less prone to settling
Cellulose Insulation Pros Cellulose Insulation Cons
The cost is 75% lower than fiberglass Needs to be chemically treated to be pest-repellant
Comes in small pieces and easy to install Flammable material and a fire-risk
R-value ranges between 3.2 and 3.5 Settles after installation which decreases its effectiveness
Loses less R-value when compressed2 Ineffective when wet and mold can grow easily
Maintains R-value even in extreme cold2 Creates a lot of excess dust

Advantages of fiberglass include:

  • Cost-Effective and Energy Saver – Not only is fiberglass made up of a relatively low-cost material, but it’s also such an effective insulator that it can help decrease your energy bill by 40%, helping you save money in the long run.
  • Long-Lasting – Fiberglass is extremely durable and can last up to 100 years in ideal conditions. Unlike other insulation materials, it also doesn’t shrink over time.
  • Non-Flammable & Moisture-Resistant – Though fiberglass may look like cotton, it’s primarily made up of glass, which means there’s a much lower risk of it catching fire or developing moisture-related problems in humid weather. 
  • Noise Insulation – Fiberglass is an extremely effective insulator not only when it comes to protecting your home against weather, but also against unwanted noise. Whether you live in a busy part of town with lots of traffic or you’ve got a loud generator right outside, fiberglass insulation can help keep your home a quieter and more peaceful place. 

Disadvantages of fiberglass include:

  • Ineffective When Wet – If your fiberglass becomes significantly wet due to a leak in your attic, the insulation will not be able to work effectively until it has been professionally dried.
  • Self-Installation Can Be Dangerous – Because fiberglass is made up of tiny glass fragments, it can be dangerous to handle it without taking safety precautions and improper handling can lead to health problems like rashes or respiratory damage. That’s why it’s always best to consult an expert or insulation contractor while installing fiberglass insulation.

What is Cellulose Insulation?

Cellulose is another popular form of home insulation. It’s typically made from 82-85% recycled material like newspaper or tiny fragments of wood.2 These are then shredded and fiberized so they’ll be able to pack tightly together and stop the flow of heat. 

While there is only one type of cellulose insulation, there are several different ways to install it:

Old Home Installation (Blown Dry)

For homes with a pre-existing structure, part of the siding will have to be removed, a row of holes will be drilled into the wall, and then insulation can be blown in dry.

New Home Installation

  • Damp-sprayed – Moisture is added to the tip of an insulation spray nozzle, activating the starch in the cellulose. It’s then sprayed over the cavities in your home. 
  • Dry-netting – A net is blown full of dry cellulose and then stapled over openings in the building.

The best method of cellulose insulation installation will depend on what kind of home you have and what tools are available to you.

Pros and Cons of Cellulose 

While there are certain advantages of having a paper-based insulation, there are also some notable disadvantages. 

Advantages of cellulose include:

  • Low-price – Because cellulose is primarily made out of paper, it’s an even more inexpensive form of insulation at about 75% of the cost of fiberglass.
  • Easy Installation – Cellulose comes in small pieces and there are many ways to install it, so it fits well with most homes’ structures but can be very messy to install. 

Disadvantages of fiberglass include:

  • Not Pest Repellant – Since cellulose is not naturally pest repellant, it’s often treated with chemicals like boric acid that claim to ward off rodents and bugs. In reality, boric acid does little to repel rodents, leaving your home vulnerable to a potential infestation. 
  • Naturally Flammable – Cellulose is also treated with chemicals to help make it more flame resistant, but because it’s made of paper, it will always pose more of a fire-risk than a non-flammable insulation material. 
  • Settles After Installation – Cellulose insulation tends to settle by several inches after it’s installed, which causes it to decrease in effectiveness. 
  • Mold Grows When Wet – Like fiberglass, cellulose is ineffective when wet, but unlike fiberglass, it can also be dangerous. The paper base of cellulose provides the perfect environment for mold and mildews to grow and the boric acid used to treat it can become corrosive when in contact with water.
  • Excess Dust – Because cellulose is essentially made up of finely shredded paper, it creates a lot of dust when it’s being installed, which makes it difficult to clean up and can turn it into a breathing hazard for those installing it. 

R-Value: The Role of Thermal Resistance

One of the most important considerations when comparing different types of insulation is R-value. R-value measures the thermal performance or resistance of a material, or in other words, its ability to keep warm places warm and cold places cold.

Materials with a higher R-value will more effectively insulate your home, helping you keep a more regulated temperature indoors and a lower energy bill. 

Different insulation materials have different ways of combating heat flow and therefore different R-values. Fiberglass’ R-value tends to range between 2.2 and 4.3 depending on the density of the material, whereas for cellulose, the R-value ranges between 3.2 and 3.5. 

This means cellulose insulation has a slightly higher average R-value than fiberglass, but high-quality fiberglass provides better thermal resistance than high-quality cellulose. 

Should I Choose Fiberglass or Cellulose Insulation?

While both fiberglass and cellulose insulation have their own benefits and can be useful in different environments, overall, fiberglass has much more advantages as compared to its downsides.

Fiberglass installation is an affordable, easy-to-install form of insulation that is compatible with most homes and protects against a lot of the dangers caused by poor insulation materials.

Because of this, we recommend fiberglass over cellulose for high-quality insulation that will last. And if you haven’t considered blow in insulation vs spray foam, read our recent blog to understand the difference between these two types of insulation, to make the most informed choice for your home.

Attic Insulation & Air Sealing: Should You Do Both?

Written by Kevin on . Posted in Attic Insulation. No Comments on Attic Insulation & Air Sealing: Should You Do Both?

Picture this: it’s a cold winter morning and you’re leaving for work. You just made some coffee and you want it to stay warm for the drive. What do you do? You pour it into a tumbler and seal it with a lid on top. 

This tumbler keeps your coffee warm much the same way attic insulation and air sealing do for your home. 

The stainless steel interior of the tumbler works like proper insulation, helping to keep heat from escaping or entering through the sides of the cup. The rubber sealing of the lid works like your home’s sealing, keeping out cold air while helping keep the warmth inside from seeping out of any gaps. 

Both insulation and sealing work in their own ways to help maintain a regular internal temperature and they’re essential parts of creating optimum energy efficiency. In this article, we’ll go over the different ways attic air sealing and proper attic insulation help stop the flow of heat and which is more important for keeping your home comfortable. 

What is Attic Insulation?

Insulation works by creating a thermal barrier between your home and the outside world. This barrier helps reflect the weather outside your home and maintain the indoor air quality and temperature inside, so you’re heating and cooling systems won’t have to work as hard to keep your home comfortable. 

However, according to Energy Star, 9 out of 10 homes in the U.S. are underinsulated.1 This means most people are likely overpaying for their energy bills due to their home’s inability to properly regulate temperature. 

The good thing is that existing insulation technology has come a long way in the last few decades and there are many insulation options for homeowners. 

Signs Your Home’s Insulation Needs Updating   

If you aren’t sure whether or not your home is properly insulated, here are some warning signs of poor insulation to look out for: 

  • High energy bills 
  • Drafts indoors
  • Temperature fluctuates from room to room
  • Cold interior walls or floors 
  • Visible joists in the attic 

If your home shows any of these signs, it might be time you had your insulation replaced. 

Types of Insulation

Insulation is not a one-size-fits-all kind of business. It comes in a variety of different materials, each of which works to regulate the temperature in your home differently:2

  • Fiberglass batts – Fiberglass batts may look like big rolls of cotton but they’re actually made of tiny pieces of fiberized glass. These fibers are spun into long blankets for easy installation. 
  • Blown-in Fiberglass – Blown-in fiberglass insulation is made up of the same material as batts, except instead of coming in big rolls, they come in small pieces that are blown into place. They’re popular for being one of the most affordable and effective forms of insulation. 
  • Cellulose – When examining Cellulose vs Fiberglass insulation, Cellulose is made of extremely finely shredded pieces of newspaper that have been fiberized to stick together and block heat flow. It’s a cheap and simple-to-install form of insulation, but it doesn’t survive well in humidity or against pests. It is actually a common misconception and marketing strategy to try and position cellulose as a pest retardant. 
  • Spray Foam – Spray foam insulation provides an airtight seal and is completely waterproof. Unfortunately, it does also come with a higher price tag, is typically used for industrial use only, and can be difficult to install without professional assistance. 

What is Attic Sealing?

Even if your home has high-quality insulation, it may not be enough to keep the temperature in your home regulated. In fact, it’s commonly thought that if you add up all the gaps and leaks in the average home’s envelope, it would be the equivalent of leaving a window open all year.3

So how can you tell if your home has a sealing problem?

Oftentimes, the signs of poor attic air sealing are similar to those of poor insulation—drafty rooms, high energy bills, uneven room temperatures—so it can be difficult to tell whether the problem you have is because of bad insulation or sealing. 

To determine the root cause, you may need to do some investigation.

Identifying the Source of Your Air Sealing Problem

Most of your air sealing problems are going to come from the parts in your home where there are natural gaps, such as where walls meet or where pipes disrupt the structure of your home.4 

There are a number of different tests you can do to figure out if you have a gap in one of these areas.

Visual Inspection

The simplest way to find significant gaps in your home’s sealing is by conducting a visual inspection of places where sealing problems commonly occur, including:5 

  • Kneewalls 
  • Soffits
  • Door and window frames
  • Plumping, wiring, and pipes 
  • Chimneys or furnaces
  • Baseboards
  • Switchplates
  • Attic hatch 

If you notice a hole in any of these places, make a note of it and come back later to seal it. 

The Light Test 

If you’re not sure where to look for gaps in your home’s sealing, the light method can be incredibly helpful. Simply turn on light fixtures in a room where you suspect there’s a leak and observe from the outside where the light shines through. Wherever you see the light shining is a place that needs to be sealed. 

The Paper Test  

If you specifically want to see how energy efficient your outside-facing doors and windows are, you can use the paper test. All you need to do is shut your window or door on a piece of paper and then try to pull it out. If the paper comes out all in one piece, the door or window will need to be properly sealed. 

The Smoke Test  

For air leaks that are difficult to locate, you can try a smoke test. Here’s the procedure:

  1. Wait for a day when the outside weather is cool and windy.
  2. Turn off all combustion appliances and block off all exterior-facing windows, doors, and chimneys.
  3. Turn on all exhaust fans that blow air outside.
  4. Light an incense stick or sprinkle talcum powder in the air around the edges of the room. Where you see the smoke or powder moving out of the room, there’s a leak that will need to be sealed up. 

How to Seal Gaps in Your Home’s Envelope

After you identify where the leaks in your home’s sealing are coming from, there are a few steps you can take to mitigate the problems, including: 

  • For large gaps, like those around knee walls and soffits: Using proper protective gear, fill a garbage bag full of fiberglass insulation and stuff it into open cavities until the bags fit tightly. Follow Attic Construction’s guide for a full breakdown on fiberglass insulation cost. 
  • For heat-sensitive areas, like those around chimneys and water heaters: Seal gaps with lightweight aluminum foil, making sure to leave a metal dam between the area and any potentially flammable insulation.
  • For smaller holes, like those around plumbing and wires: Use an expanding foam or caulk to fill up cavities.

Always make sure you’re performing these insulation fixes safely, using the proper protective gear. If you have any questions, reach out to the experts at Attic Construction.

Attic Insulation vs Air Sealing: Which Is More Important?

Both insulation and sealing work together to regulate the temperature of your home, but which is more important when it comes to keeping energy costs in your home down? 

To answer that question, we’re going to revisit our tumbler analogy from earlier. 

Let’s say you were to take your hot coffee with you to work in a non-insulated container, like a mug or paper cup. Since there’s no insulation to keep the heat of your drink from leaking out the sides, where it is surrounded by winter air, your drink will quickly lose heat and will likely be cold by the time you arrive at work.  

If, on the other hand, you were to bring your drink to work in an insulated tumbler without the lid, your drink will still cool down while you drive but at a much slower rate, so your drink will likely still be warm enough to drink by the time you arrive at the office. 

The reason for this is insulation does a lot more work to regulate temperature than sealing does as it covers more surface area in your home. As long as the gaps in your home aren’t major and clearly visible from the outside, having high-quality insulation is going to be a more essential part of keeping your home’s temperature regulated and your energy bill down.

9 Easy Ways to Lower Your Power Bill

Written by Kevin on . Posted in Insulation. No Comments on 9 Easy Ways to Lower Your Power Bill

Your home is your safe haven. It provides you with comfort and security. But owning a home also comes with a lot of expenses. One of the biggest culprits? Your power bill. 

By understanding your electricity usage, you can take steps toward making your home more energy efficient to save you money. 

Check out these 9 easy ways to lower your power bill. 

#1 Conduct a Home Energy Audit

Conducting a home energy audit is a great way to start your journey toward lower power usage. An energy audit will determine your home’s energy consumption and where exactly your home is losing energy. By identifying where your home is losing energy, you’ll know where to make repairs or replacements to make your home more energy efficient. 

While it’s possible to perform a home energy audit yourself, it requires diligence and patience. Hiring a professional will guarantee a thorough and accurate assessment, saving you money in the long run. 

#2 Perform an Attic Inspection

Similar to an energy audit, an attic inspection will determine improvements that can be made to your attic to make your home more energy efficient. During an attic inspection, a professional will assess the following:

  • The number and quality of your attic vents
  • The amount of insulation, how well it has been installed, or if your insulation needs to be replaced
  • Whether your attic is home to a rodent infestation or mold
  • Check for potential air leaks

A well-vented, well-insulated attic in excellent condition is great for energy saving as your heating and cooling system won’t have to work as hard to regulate your home’s temperature. 

Since heating and cooling systems account for about 47% of your electricity bill, reducing the amount of work they do and the amount of electricity they use means huge savings. If you live in a hotter climate, be sure to check out the best insulation for hot climates.  

#3 Insulate Your Attic and Crawl Space 

Attics and crawl spaces are both part of your home’s envelope. Your home energy audit and attic inspection may determine that your home needs better insulation. If this is the case, your attic and crawl space are the most important places to start for lowering your electricity bill. 

By insulating these spaces properly, you create a more effective seal. This makes it easier for your heating and cooling system to regulate your home’s temperature. 

#4 Check Seals on Windows and Doors

Improperly sealed windows and doors are big culprits for energy leaks and heat loss. It’s important to ensure windows and doors are completely closed when air conditioning your home in the summer and heating your home in the winter. Here are some other simple steps you can take to further ensure a tight seal:

  • Use weatherstrips
  • Replace old door sweeps
  • Apply window film
  • Re-caulk the exterior of your windows and doors

#5 Clean and Replace Your HVAC Filters

A dusty filter may not seem like a big deal, but it will actually make it more difficult for your HVAC system to run efficiently. Dust and dirt block the flow of air, forcing your system to work harder and use more energy to circulate cool or warm air. 

Over time, unchanged filters can even cause HVAC systems to break down, ultimately affecting your energy costs. Regularly cleaning your HVAC filters is an easy way to maintain your system and keep it running efficiently. 

#6 Adjust Your Thermostat

Consider adjusting the temperature on your thermostat when you’re not home or when you go to sleep at night. In the winter, you can easily add extra blankets to your bed, or sleep in a cozy sweater to stay warm. In the summer, you can use linen sheets or a cooling duvet to stay cool. You can also consider investing in a programmable thermostat, or learn how to keep your house cool without AC.

These small adjustments will lead to big savings. In fact, the Department of Energy estimates that for every eight hours you lower your thermostat by one degree, you can save 1% on your power bill.

#7 Beware of Energy Vampires

Turning off an appliance or electronic doesn’t necessarily mean it has stopped using electricity. Many appliances and electronics instead go into standby mode. This means they still pull a trickle of electricity. 

Over time, energy vampires can account for as much as 5% of your power bill. Some of the most common energy vampires are:

  • Set-top boxes
  • Computers (both laptops and desktops)
  • Printers
  • DVD players
  • Routers and modems
  • Gaming consoles
  • Televisions

So how do you combat energy vampires? Simply unplug these devices when you’re not using them. 

For even more convenience, use a smart power strip. Smart power strips completely shut down power to electronics that go into standby mode.

#8 Swap Out Your Lightbulbs

Another easy way to reduce your power bill is by replacing incandescent bulbs with compact fluorescent bulbs or LEDs. Incandescent bulbs are a huge waste of energy, with only 10% of their energy resulting in actual light. (The other 90% is given off as heat.) 

By swapping out the bulbs in just five of your most-used light figures, you can save $75 a year. 

You can also consider adding dimmers to your lights to control their level of brightness. By controlling the brightness, you control the amount of electricity being used. 

#9 Turn Off The Lights!

Not only is turning off your lights one of the easiest ways to reduce your power bill, it’s also free! Turning off the lights in rooms you’re not using or when you leave the house can significantly reduce your electricity use. It also helps extend the life of your lightbulbs. Win-win.

For total peace of mind, you can even install timers on your lights. If your lights are on a timer, you never have to worry about accidentally leaving the lights on ever again. 

Energy Efficiency is the Key to a Lower Power Bill 

As a homeowner, you depend on electricity to keep your home running smoothly and comfortably. Following our 9 simple steps can quickly and easily make your home more energy efficient. You’ll lower your power bill and save money without sacrificing your comfort. 

Should you find gaps in your thermal envelope or want to insulate your attic to lower your AC bill—make sure you do it properly, as there are potential harmful side effects. The experts at Attic Construction have the experience and tools needed to ensure this is done safely.
