Your attic is an essential space—it’s the place to store everything from holiday decorations to camping equipment and the first line of defense against a high energy bill.

That said, your attic can wreak havoc on your wallet if it’s not properly insulated. This is because your attic’s insulation helps regulate your home’s heat flow. In short, an under-insulated attic can greatly drive up energy costs.

But how do you know how much insulation you need to properly insulate your attic?

The answer: an attic insulation calculator.

Knowing what an attic insulation calculator is and how it works will greatly benefit you when it comes to insulating your attic.

Calculating Insulation Requirements

Although it sounds like an intricate machine, an attic insulation calculator is simply a mathematical formula that lets you know roughly how much insulation you’ll to properly insulate your home.

In its most basic sense, insulation consists of any material placed in a home’s gaps or crevices in order to regulate heat flow. Without proper insulation, heat escapes from your home in the cold winter months and enters your home during summer.

To calculate insulation requirements, follow the steps below.

#1 Measure Your Attic

If your attic is square or rectangular, measuring your attic should be a piece of cake. Simply measure your attic’s length and width and multiply those two figures together to yield your attic’s square footage.

If your attic consists of triangular spaces, you’ll need to measure the height and width of each triangle. Then, divide the base in half and multiply it by the triangle’s height to yield the area’s square footage. 

#2 Measure Current Insulation Levels 

If your attic’s uninsulated, you have no old insulation to measure. But if you have existing insulation, take your insulation’s measurement by measuring from the attic floor to the top of your insulation. With this information in hand, you’ll know how much more insulation you might need to improve your energy efficiency.

If you’re unsure of how much more insulation you’ll need, consult the Department of Energy’s insulation chart.

#3 Calculate 

To calculate how much insulation material to purchase, simply divide your attic’s square footage by the square footage of insulation in the manufacturer’s package (assuming you’re purchasing pre-cut batts or rolls). This will give you a rough estimate of how much insulation you’ll need and how much you can expect to pay for proper insulation.

You now have an easy and efficient attic insulation cost calculator.

Beyond Square Footage: Calculating Insulation Needs By Material

While the above calculator can give you a rough estimate of how much material you’ll need, the specific amount will vary based on the material you choose to insulate your attic or crawl space.

Though there are several different types of attic insulation, the most common include:¹

• Blanket – Made from fiberglass, natural and synthetic fibers, and mineral wool, blanket insulation comes in two forms: rolls or pre-cut panels known as batts. Inexpensive and easy to apply, blanket insulation material is perfect for spaces between joints, studs, and beams.
• Loose-fill – Constructed from cellulose fiberglass and mineral wool, loose-fill insulation is ideal for areas that are already finished or areas with obstacles or unusual designs. Although you can install loose-fill insulation by hand, it’s most commonly installed by blowing the insulation from a blower attached to a hose. Loose-fill insulation is perfect for attics.
• Spray foam – Similar to loose-fill insulation in that it’s perfect for attics, spray foam insulation is typically installed via small spray containers. Spray foam insulation is manufactured from various materials, including phenolic and polyurethane. 
• Reflective – As its name implies, reflective insulation works by reflecting heat away from a home. It’s made from various materials including foil kraft paper, cardboard, and plastic film, and regulates downward heat flow exceptionally well.

These different materials also have different insulation R value types. A measurement of an insulation’s effectiveness at regulating heat flow, R-value is a useful tool when deciding between different types of insulation and the amount of insulation you’ll need. 

It’s best to consult an insulation chart to determine precise R-values and costs, but in general, materials that have lower R-values, such as blanket insulation, cost less per square foot per R-value than materials with higher R-values, such as spray foam.

Calculating R-Value

To calculate R-value, divide a material’s thickness in meters by its thermal conductivity. R-values are measured in ft. °F. h/BTU. In general, the higher a material’s R-value, the better it is at reducing heat flow.

While your R-value differs based on a number of factors, chief among these is your home’s location. For instance, while attics in the Upper Midwest and New England require insulation with R-values ranging between R49-R60, attics in the Deep South require insulation with R-values ranging between R30-R60.

As a homeowner, you have numerous tasks on your to-do list, from finishing your basement to finally replacing that burnt-out porch lightbulb.

If you only use your attic to store holiday ornaments, its problems may be the last thing on your mind. But if your neighbor or contractor mentions that your insulation looks like it may contain asbestos, you might be left wondering, is asbestos in the attic dangerous?

The short answer is yes. Long-term exposure to asbestos can cause serious health problems.¹

In this guide, we’ll explain the ins-and-outs of asbestos, its potential health hazards, and the best way to remove the harmful substance from your home. If you don’t know what asbestos in an attic looks like, our team is here to help. 

What is Asbestos?

Before the 1980s, asbestos fiber was commonly used as a building material. Builders previously used asbestos because it resists electricity, corrosion, and heat—making it an ideal insulator.² 

This naturally occurring mineral is toxic—and unfortunately, its tiny particles make it easy to inhale. Over time, constant exposure of harmful asbestos fibres can lead to lung disease or a number of other health problems.

While the risks of asbestos are now well-understood, if your home was built before the 1980s, your insulation could still be a cause for concern.

If asbestos is in an attic, it’s usually in vermiculite insulation.³ 

Not sure what material was used in your attic? Take a look to see if it has the following characteristics:

• A pebble- or stone-like texture 
• A light-brown, greyish-silver, or gold hue
• Shiny flecks throughout

If you find what appears to be vermiculite insulation in your attic, don’t immediately panic.

Not all vermiculite insulation contains asbestos. A house built after the 1990s is less likely to have an asbestos problem. However, it’s always best to be cautious and take the necessary safety precautions when testing your insulation material. 

Health Impacts of Asbestos

Vermiculite insulation that contains asbestos is most dangerous if disturbed. For example, dedicated DIY-ers may try to replace their insulation material on their own. But removing the old insulation means sending asbestos fibers into the air.

Without property safety precautions, these asbestos fibers can be inhaled into the lungs and cause serious health problems. 

The four most common health impacts from asbestos exposure include:⁴ 

• Asbestosis – A non-cancerous condition that includes difficulty breathing because of scarring in the lungs.
• Pleural Disease – A non-cancerous condition that includes the thickening of the membrane around the chest cavity and lungs as well as a build-up of fluid around the lungs. 
• Mesothelioma – A rare type of cancer that can impact the lining of the chest cavity, the lungs, the abdominal cavity, or other internal organs. 
• Lung Cancer – A type of cancer in which a malignant tumor obstructs airways. 

With most of these conditions, it can take a minimum of 15 years to develop symptoms and receive a diagnosis.

So it’s best to have your house checked for asbestos particles even if you’re not experiencing exposure symptoms. The cost of professional asbestos removal is certainly worth it when considering the risk it can have on your health.

Who Is At Risk? 

Asbestos is toxic and can be extremely dangerous. However, not all people exposed to asbestos develop health problems. A person’s risk for developing a health problem from exposure depends on multiple factors, including:⁵

• How long and often a person is exposed
• The amount of asbestos in the air
• Whether the person has a history of respiratory conditions 
• Whether the person smokes 
• How long it has been since the exposure

Often, asbestos-related health conditions arise from years of exposure in the workplace.

However, home-related exposure is still possible and can still lead to health problems. 

What To Do If You Suspect Asbestos 

Even if you’re not sure if your attic insulation contains asbestos, it’s important to take precautions. 

• If you’re concerned there might be asbestos in your attic, the first rule is to leave it alone. Any disturbance could lead to scattering asbestos fibers into the air around you.
• Until you have your insulation inspected by an accredited asbestos expert, restrict access to the attic. Don’t store anything in the attic or move your pre-existing storage boxes. 

Avoiding all contact with the insulation is the most important step you can take to keep your household safe. Do not remove the insulation yourself, and be aware of disturbing it through other house renovations. Performing any renovations near the asbestos such as drilling, hammering, sanding, and more could disturb it and send fibers into the air. 

Instead, call a professional to help you safely remove and replace asbestos insulation.

When you find out that you have asbestos insulation in your attic, your first thought is that it must be removed immediately. Your second thought is how much is asbestos abatement going to cost?

We know the idea of asbestos lurking above you is disturbing—after all, you’ve heard countless stories about the dangers of asbestos exposure such as lung cancer and other illnesses. And, while asbestos is indeed hazardous, we’re here to reassure you that the insulation in your attic can be dealt with without risking your physical or financial health.

In this blog, we’ll explain the cost of asbestos removal and the proper steps to take if you suspect asbestos material is lurking in your attic.

The Cost to Remove Asbestos Insulation in Attics

We’ll come out with the bad news right away—we can’t give you a precise quote for removing asbestos from your attic ceiling.

As we’ll explain, asbestos removal is a multi-step process involving, at minimum, an asbestos inspector and a certified asbestos removal professional that can take care of the old insulation.

Therefore, the asbestos removal cost will depend on several factors including:

• Where you live – Because of the potential health hazards, asbestos remediation is never a DIY job. And just like car insurance and real estate, the cost of asbestos removal services varies between geographic regions.
• The contractors you hire to inspect and remove – Your local market features contractors with varying degrees of experience and various demands on their schedules. No matter what, it’s important to hire an asbestos contractor from a reputable asbestos disposal company who has completed the Environmental Protection Agency’s asbestos training to have your asbestos removed.1 Beyond that, look for professionals with good reviews and affordable rates.
• The size of your attic – Do you live in a two-bedroom home with a relatively small attic? You’ll likely be looking at a lower overall asbestos removal cost than would the neighbor with the 1,000 sq foot attic above their mini-estate. 
• The amount of insulation you need to remove – You might think that your attic’s square footage is the only factor involved in the volume of asbestos contamination and the cost of removing asbestos. However, the total amount of insulation depends on the thoroughness of the original contractor’s job, whether they used a mix of materials, and the specific shape of your attic.
• The type of new insulation you elect to install – Once you’ve removed the material containing the hazardous material of asbestos waste, you’ll likely want to replace the insulation right away. Otherwise, you’ll risk higher utility costs. Likewise, a lack of insulation protection could expose your home to further damage from humidity, extreme heat, and extreme cold. 

Ready to start getting quotes?

Not so fast. In some cases, attic insulation removal is not the best option—and even if it is, it’s important to thoroughly understand asbestos material and the risks of asbestos exposure.

Next, we’ll lead you through a step-by-step guide to finding the best for your specific asbestos abatement situation and budget.

Step 1: Understand Your Insulation

You already know asbestos is dangerous. But do you understand what makes this building material risky?

In short, asbestos is a toxic mineral with fine particles that can easily be inhaled, leading to lung damage and serious health issues. Agitating or removing your insulation can release these particles.

If you’re concerned about asbestos contamination, you won’t want to poke, prod, or remove your old roof insulation yourself or undertake disposal. Instead, take steps to make sure it actually contains this mineral and consider asbestos testing.

There are two types of insulation used in residential properties that may be an asbestos containing material: batt insulation and vermiculite.

Batt Insulation

The good news is it’s very rare to find batt insulation containing asbestos still in use.² The loose-fill style of insulation containing asbestos was far more ubiquitous. 

However, if your attic has very old batt insulation, you should get a laboratory test to confirm that it’s asbestos-free.

Vermiculite Insulation

The biggest concern for asbestos in attics is vermiculite insulation.³ Vermiculite insulation is made of small pebble-sized pieces. It’s generally silver-gold or brownish-grey and looks like a mini-accordion. 

Like asbestos, vermiculite is a mineral. On its own, vermiculite isn’t harmful. Unfortunately, most of the vermiculite used to insulate attics in the United States from the 1940s through the 1970s came from the same mine in Libby, Montana.⁴ This mine was contaminated with asbestos, tainting all of the vermiculite that came from it. 

Step 2: Avoid Disturbing Your Vermiculite Insulation

If you spy vermiculite insulation, your first step is alerting all family members to avoid entering the attic, removing stored boxes, or agitating the insulation.

Why?

Asbestos is at its most hazardous when it’s friable, or easily crumbled. This allows the tiny fibers to break free into the surrounding air where they’re inhaled. The small pieces of vermiculite used in attic insulation can release many asbestos fibers when disturbed.

If the option to leave vermiculite insulation alone exists, the EPA recommends that you do just that.⁵ Think of it like a bumblebee. If you don’t bother the bee, it won’t harm you. However, if you frighten it, you might get stung. If undisturbed, the vermiculite won’t become friable. If you move it around, it can crumble further and release microscopic fibers into the air of your home.

Unless you plan to finish your attic and use it as a living space, odds are you don’t spend much time up there. If this is your family’s situation, the EPA recommends that you avoid:⁶

• Storing boxes near any place in your attic that will require you to disturb the insulation to move the boxes.
• Letting children play in the attic if vermiculite is exposed.

The bonus? You’ll save money by avoiding the cost of asbestos removal.

Step 3: Before Removal, Hire an Inspector

While it’s recommended that you leave vermiculite insulation alone if at all possible, we know there are situations where it must be removed. These include:

• Rodent or other pest infestations
• Water or fire damage to the attic
• Renovation requiring removal of existing structural elements

When you’re ready to hire an asbestos removal company, the first step is finding a qualified asbestos inspector to assess the insulation.¹ They’ll take samples and discuss the removal of the vermiculite with you. You’ll also receive a written summary of their recommendation for removal. 

The inspector will also follow up after the insulation has been eliminated to ensure that the job was done correctly. 

Step 4: Hire a Contractor

Hiring a contractor to remove the asbestos can be one of the most difficult steps. You need a person who will follow guidelines precisely to avoid contaminating your home with asbestos fibers. 

As we’ve noted, the EPA stresses the importance of only choosing contractors certified to remove asbestos. Each state maintains a list of currently licensed contractors.⁷ They also recommend that you get everything in writing from the contractor you select for the insulation removal.

Once again, costs can vary between contractors, so we recommend getting several quotes.

Step 5: Monitor the Home

After the contractor’s work is complete, either the inspector who provided your original evaluation or an independent air testing contractor will need to monitor the air quality of your home. 

• It’s important to have someone other than the contractor who performed the removal work do this step to avoid a conflict of interest.
• For example, if you hire an inspector who works in the same office as the contractor you choose, they might act in their business’ best interest rather than yours. Working with two people who don’t have connections to one another ensures you aren’t caught in the middle.

Keep in mind that this extra visit will likely come at an additional cost. However, it’s more than worth it to ensure your home is safe and healthy.

Step 6: Install New Insulation

The final step in the vermiculite removal process is to install new insulation. We know—it might be tempting to go without insulation, especially if you live in a warmer climate. However, it’s critical for temperature regulation no matter where you are. 

The right insulation keeps warm air from leaching into your air-conditioned space and cold air from seeping in from outside. Both of these mean lower energy bills and a more comfortable home.

Your exact insulation needs will depend on the climate where you live and the size of your attic. A professional can advise you on the best insulation for your home.

We love the charm, character, and quirks of old houses. How many new homes have true hardwood floors, built-in cabinets, and stained glass windows? 

Of course, squeaky floorboards, dusty attics, and strange room shapes are additional parts of owning an older home. But what do you do if your house contains hidden dangers behind the charming features?

Unfortunately, if you’re buying an older house, asbestos is sometimes part of the deal. This toxic mineral was once prevalent in attic insulation and other building materials, and may still be lurking in your home. Asbestos can be dangerous for you and your family, which is why it is so important to check for asbestos contamination as soon as possible. 

But what does asbestos look like and how do you know if you have it? We’ve assembled this guide to help you understand the dangers of asbestos, identify it in your home, and take appropriate steps for safe, professional removal.

What Is Asbestos?

“Asbestos” refers to a group of six different minerals that are made of very thin fibers.¹ Each of these minerals is:

• Stong
• Fireproof
• Heat resistant
• Chemical resistant

 These characteristics once made asbestos fiber an appealing additive to many construction products. 

Like other minerals, asbestos fiber is mined from the earth. It’s found throughout the United States and in many other countries. While the peak of asbestos mining in the U.S. occurred during the 1960s and 70s, the use of asbestos dates to a much earlier time.

A Brief History of Asbestos

Asbestos was first incorporated into pots and cooking utensils over 4,500 years ago by Scandinavian cultures.² 2,000 years later, the Ancient Romans noticed that slaves working with asbestos became ill, although this knowledge didn’t stop its use. The Industrial Revolution spurred the commercial manufacture of asbestos products in the late 1800s. This ubiquity led to the discovery of a link between cancer and asbestos exposure in the 1930s.

Unfortunately, asbestos had become far too popular and valuable, so the industry ignored the warnings from scientists and medical professionals until Congress finally began federal regulations on asbestos in the 1970s. 

In 1989, the Environmental Protection Agency (EPA) attempted to ban the use of asbestos in new products and recommended phasing it out in others. The ban was overturned two years later after heavy pressure from lobbyists for the asbestos industry. 

Despite the known dangers, asbestos is still included in many products today.

The Dangers of Asbestos Exposure

Long-term exposure to asbestos fibers can cause serious health problems.

The lungs are most seriously impacted by inhaling needle-like asbestos fibers. The three lung diseases closely associated with asbestos are:³

• Asbestosis – This chronic condition aggravates lung tissues and creates scarring. It can contribute to cardiac failure and is often fatal.
• Mesothelioma – Mesothelioma is a cancer of the membrane that lines the lungs, abdomen, chest, and heart. Almost every case diagnosed in the U.S. is linked to asbestos exposure.
• Lung Cancer – Other lung cancers are the leading cause of death among those who have been regularly exposed to asbestos. Smoking cigarettes combined with asbestos exposure makes one even more likely to develop lung cancer.

Signs You May Have Asbestos in Your Home

First things first: the only sure way to know if materials in your home contain asbestos is to get them tested in a laboratory. 

However, there are some clues that your home might have asbestos. Do any of the following apply to your house?

• Built before 1980
• Features popcorn ceilings and textured paint
• The exterior is built of cement shingles and siding
• Attic insulation is loose fill (i.e., not made of a uniform material like foam blocks)

If so, there’s a greater likelihood of asbestos—and you’re most likely to find this dangerous substance in your attic.

Insulation is the most commonly known asbestos-containing product still present in many homes. Two types of insulation—vermiculite and batt—can contain asbestos, although it’s most often found in the loose-fill style of insulation, vermiculite.⁴ 

Identifying Asbestos in Your Attic

Although many attics are empty, ignored spaces, some homeowners want to put that square footage to good use. We don’t blame you. A well-insulated attic is a perfect place to store your seasonal decor, clothing, and keepsakes. 

So how do you know if it’s safe to put your attic to work for you?

First, we want to be clear that you shouldn’t disturb anything in your attic that you think might contain asbestos. If your attic is finished, look out for ceiling tiles, popcorn ceilings, or other textured paints. These would need to be laboratory tested to confirm the presence of asbestos. 

Unfinished attics might have more visible evidence of asbestos.

• If the insulation is made from vermiculite, there’s an excellent chance it contains asbestos. 
• You can identify vermiculite by its appearance. It’s made from small, pebble-like bits. They’re usually about a quarter of the size of a paperclip and are brown, silver, or gold. 

Interestingly, vermiculite itself is not harmful.⁵ However, most of the vermiculite used in the U.S. was mined from the same place—a mine contaminated with asbestos.

How to Get Rid of Asbestos in Attics

The idea of asbestos covering your home is disturbing. We want to reassure you that most asbestos-containing materials are only harmful if they’re disturbed or damaged. 

If you suspect your home may have asbestos, the best approach is often to leave it alone.

To help you understand, imagine the dandelions that pepper your yard in the spring. Once they turn white, you can blow on them and they release tiny bits of fluff into the air. Think about disturbing asbestos in a similar manner. When left alone, you’re not likely to experience harmful effects. However, when asbestos is disturbed, it releases deadly fibers into the air where you can inhale them.⁶

“Friable” is the term used to describe asbestos that can be crumbled and released into the air. Asbestos is at its most dangerous in this format. 

Removal and Replacement

If your attic has vermiculite insulation and you want to remove it, keep in mind that the EPA recommends leaving it alone unless absolutely necessary.⁷ If removing the loose fill insulation is your only option, don’t do it yourself under any circumstances. 

If you have no choice but to remove existing asbestos insulation, here are the steps to ensure your safety:

• Test the material – Contact a certified professional to make sure you are not dealing with asbestos containing material. If you need help finding one, call your local EPA office. They can point you in the direction of professionals who have completed an asbestos safety course. A professional can take a sample of any material you suspect of containing asbestos and send it to a lab to test for confirmation.
• Remove insulation safely – Once your suspicions have been confirmed and you’ve decided to proceed with asbestos removal, a professional will employ what’s known as a negative pressure enclosure. This prevents any loose fibers from escaping and contaminating the rest of your house.
• Monitor the air – The contractor who removes the insulation should continue to monitor the air in your home after removal to ensure your safety. 
• Replace it with new insulation – Today’s insulation isn’t made with asbestos. Consult with a professional to identify the right insulation material for your geographic area, home, and budget.

Other Hiding Spots for Asbestos

While you’re most likely to find asbestos in attic spaces, there’s a chance that other construction materials contain this toxic mineral. If you suspect asbestos in your attic, do your due diligence in inspecting the following areas before you undertake any home renovation projects.

• Exterior Surfaces – Asbestos can be found in cement roofing and siding shingles on the exterior of your home.⁸ As long as these are left alone, they’re not likely to pose any risk to you. 
• Floor and Ceiling Tiles – Asbestos was once used in the adhesive backing on vinyl flooring sheets and stick-on-tiles. Ceiling tiles can also contain asbestos fibers. Pulling up floor tiles can be problematic because you’ll likely scrape the adhesive and release fibers into the air when you remove them.⁹
• Textured Paint – Popcorn ceilings aren’t pleasant to look at and they can contain asbestos. The removal of a popcorn ceiling or any textured wall paint containing asbestos must be done by a professional to prevent hazardous exposure.¹⁰ In many cases, it’s better to cover the ceiling or textured paint instead of removing it.
• Pipes – Asbestos is commonly found coating hot water pipes in old homes. Old pipes might also be covered with tape that contains asbestos.

Lead. Radon. Asbestos. These words scare any homeowner since they indicate serious issues that could lead to expensive home renovation costs.

Toxic asbestos is particularly common in homes built before 1980. Because this mineral is soft, heat-resistant, and relatively inexpensive, it was once a popular material for insulation—particularly in attics. Unfortunately, inhaled asbestos can lead to various long-term health problems including cancer.

So, is asbestos in attics dangerous for your family? What does asbestos insulation look like in attics?

Breathing in asbestos fibers can be a health risk but While it may seem like a burden, the asbestos removal costs far outweigh risking your health. In this short guide, we’ll explain how to identify asbestos insulation in attic spaces and the steps you can take to safely remove this unwanted material from your home.

Identifying Asbestos

First things first: take a look at your attic insulation.

• If you have batt or foam board insulation, you’re probably in the clear. Batt insulation comes in a famous fuzzy pink (and in other colors), while foam board insulation is just what it sounds like—boards of foam. In fact, any insulation that comes in uniform sizes that are cut to fill your homes’ unique contours is unlikely to contain asbestos material.
• If you have blown-in or loose-fill insulation, asbestos fibers may be an issue. If your attic looks more like a white or gray construction site than a blanket-swaddled chamber, do a little more observation to uncover the likelihood of asbestos.

If you’ve identified blown-in or loose-fill insulation, the next step is to discern whether the fill substance is vermiculite, which commonly contains asbestos exposure.

The giveaway sign of vermiculite insulation is that your attic looks like a gravel path, filled in with a substance with the following characteristics:¹

• Particles with a pebble-like shape and appearance
• Grey-brown or silvery-gold color, shiny as opposed to other types of blown-in insulation 
• A lack of paper or another backing to provide it with a uniform structure

Age Matters

Was your home built before the year 2000? Don’t panic!

Since the 1990’s, asbestos insulation has been phased out of use. Research suggests that homes built before the new Millenium are significantly more likely to have asbestos insulation than homes built after.²

This risk becomes larger and larger the further back one goes. For example, a home built in the 1990s is much less likely to contain asbestos material than one built in 1960. It’s important to keep track of insulation age. ​​Replacing attic insulation is very important when the insulation hasn’t been replaced in a long time.

What To Do If You Suspect Asbestos

So you think you might have vermiculite insulation?

While you probably want to take action right away, the last thing you should do is try to remove or replace the insulation material yourself.

Why? Asbestos has been linked to lung diseases including cancer, mesothelioma, and asbestosis. ² And you’re most likely to inhale the fine, toxic particles after disturbing the asbestos, which distributes its dust into the air, contaminating the air quality in your home.

To safely handle asbestos dust, you’ll need proper personal protective equipment (PPE) to protect you from inhaling asbestos fibers. And don’t assume your N95 mask is adequate-if you get particles on your clothes, you could easily transport them throughout your home.

Instead of trying a DIY solution, take the following steps.

Step 1: Leave the Area and Limit Your Exposure

Don’t stand there in your attic Googling pictures of vermiculite.

Immediately remove yourself from the area that you suspect might have asbestos insulation material.

Repeated and prolonged exposure exacerbates the effects of asbestos dust. Therefore:

• Refrain from removing or relocating items that are stored in the attic. 
• Let all household members know about the potential danger.
• Keep the door or attic entrance shut until you’ve had a professional assessment.

Step 2: Call a Professional

If you think you might have asbestos, the first thing you need is a professional opinion. It’s still possible that your attic is insulated with another material—and the sooner you know, the sooner you’ll have peace of mind.

If you do need the asbestos insulation in your attic removed and replaced, leave it in the hands of professionals who can safely remove the material while recommending the correct modern material for your home and climate. Removing attic insulation by hand, especially Asbestos removal, can be extremly dangerous when not done properly, so it’s best to call a professional. In general, it’s best to hire a professional for insulation installation and removal, whether it’s fiberglass insulation installation or asbestos removal.

Picture this: you’re opening up your first utility bill of the summer, cold lemonade in hand. You’re proud of yourself for keeping the air conditioner on a reasonable temperature, and you feel relaxed as the bill slides out of the envelope.  

But then you read the total—and it’s far more than you anticipated. 

Keeping your home cool is difficult during the warmer months with outdoor air reaching high temperatures. It can be even more difficult if your attic space is not properly ventilated and insulated. An attic fan is one popular method of attic ventilation. But, how does an attic fan work? And is an attic fan installation really the answer to your summer cooling issues? We’ll explain in this guide.

Pros and Cons to Using an Attic Fan

An attic fan is almost exactly what it sounds like: a fan installed in your attic to move warm air out of your home and add cooler air into it.  

How well do they work?

On one hand, attic fans can be very useful in locations that are cooler in the evening, such as Portland or Seattle. On the other hand, they don’t work as well in consistently warmer places like Arizona and California and are less efficient than other options.

Let’s dig in.

Pros of Attic Fans

There are a few reasons why an attic fan might be a step in the right direction when thinking about caring for your home and those in it:

• Attic fans use less energy than air-conditioners – Many homeowners use thermostat-controlled attic fans to ensure further efficiency of maintaining attic temperature. This means that when the attic hits a certain temperature, the attic fan will immediately start and keep working until the attic has dropped below the set temperature. As a result, you save money and use less energy.
• Attic fans can also keep moisture out of your home – Sometimes, cool A/C air and hot attic air can combine to form moisture in your attic space, creating an ideal environment for mold. Attic fans work by pushing hot air out to prevent a buildup of harmful mold.¹ Therefore, an attic fan can protect the wood in your roof and ceilings and improve its longevity.

Cons of Attic Fans

Energy savings and protection from mold seem like great perks. So, then what are the negatives of attic fans? In short, attic fans may not be as helpful as they seem:

• They need very specific circumstances to work effectively – Attic fans are not useful in all environments. If there is not cool enough air outside, then the attic fan will simply replace the hot air in your attic with more hot air. This could cause your attic fan to work overtime and ultimately would not keep your attic cool. 
• They do not work as well when used in conjunction with air conditioners – Why not? Energy Star explains that “if your attic has blocked soffit vents and is not well-sealed from the rest of the house, attic fans will suck cool conditioned air up out of the house and into the attic.”² Furthermore, keeping windows and doors closed (as you’ll want to when using A/C ) is not advisable with attic fans. 
• They can be expensive and inefficient – An attic fan is just one more expense on your electricity bill. Even if a fan does reduce your need for air conditioning, you may not see any savings. Additionally, they won’t work to cool your entire house, which may not provide any benefits during the warmer months when temperatures can reach the triple digits. Instead, attic fans only circulate air within the upper portion of the house. 

This means that an attic fan could end up costing you more money in the long run, especially if used in conjunction with an air conditioner.

Even more importantly, if your attic is not well-insulated and does not have proper ventilation, the attic fan yet again loses its energy efficiency. 

The good news? Proper insulation and ventilation can have the same positive impact as an attic fan, helping keep your attic cool, dry, and inhospitable to mold.

Keep Cool With Attic Construction

When thinking about all of this information, it is easy to get overwhelmed. How can you best protect your home from external heat and moisture? We’re here to help. 

When an attic is properly insulated, it restricts the movement of air, which will save energy and money while keeping hot air out. Proper installations of soffit vents and ridge or gable vents also help to facilitate the proper type and amount of airflow to keep things like mold away from your roof and ceilings. 

Having up-to-date attic insulation and attic ventilation that is well installed is the key to your home’s success. At Attic Construction, this is our specialty and we’re here to provide insight on common attic insulation mistakes to avoid. 

With professional help, an attic fan may prove unnecessary altogether, and you‘ll still be able to keep those bills lower and your home cooler. For more information on concerns like preparing an attic for cold weather or detecting thermal leaks, visit Attic Construction today for a consultation.

Your attic does more than providing storage space for your stuff. It’s also designed to protect your home from the elements: cold, heat, and humidity.

But for your attic to do its job, you need proper attic insulation.

The trick, of course, is doing it right. Insulation is a skilled trade, and it takes time and practice for a safe and effective insulation installation. Without expert help from an insulation contractor, it’s easy to make costly or even potentially hazardous errors.

Don’t waste time and energy. Read on to avoid the five most common DIY attic insulation mistakes.

What Insulation Is and How It Works

First things first: how does insulation work? To answer this question, you’ll first need to understand how heat flows. 

Heat circulates in three different ways: conduction, convection, and radiation. 

• Conduction is the way heat transmits through materials.
• Convection is the way heat circulates through liquids and gases.
• Radiant heat, also known as thermal radiation, heats anything solid in its path, which then absorbs the energy. For example, this is how the sun warms the earth.

Insulation works by slowing conductive heat flow through the walls of your home. To a lesser extent, it also slows convective heat, which is the flow of heat through the air. 

Proper home insulation can save you up to 20% on heating and cooling costs while keeping you comfortable year-round.¹ And the appropriate amount of attic insulation results in less wear and tear on your HVAC unit.

Insulation Through the Seasons

Regardless of the mechanism, heat flows from warmer to cooler air until there is no longer a temperature difference between the two. 

• In the winter – During this time, you should be preparing your attic for the cold. Heat will flow from the heated interior spaces of your home to adjacent colder spaces such as the garage, unheated attic, basement, and outdoors. To maintain interior comfort, your home’s heating system should replace the heat lost in the winter.
• During the summer – In warmer months, heat flows from the warmer outdoors to the inside. The heat gained in the summer must be removed by the cooling system.

Properly insulating your home will decrease the amount of air needed to be replaced by your home’s HVAC system by providing an effective resistance to the flow of heat, which will result in energy savings and dollar savings.

Proper attic insulation  can also prevent:

• Gradual damage to your home caused by heat and moisture
• Water or condensation from seeping in and eroding the walls.
• Excess summer heat that can cause shingles to swell and break.

Now, you understand all of the benefits and you’re ready to insulate your attic.  So what are the common attic insulation mistakes to avoid?

Mistake #1: Using Incorrect Materials

The first step to a proper insulation job is choosing the right material. Insulation comes in many different forms:² 

• Fiberglass
• Cellulose
• Rock and slag wool
• Natural fibers
• Foam boards
• Reflective foils
• Polyurethane
• Vermiculite and perlite
• Cementitious foam
• Phenolic foam
• Urea-formaldehyde foam

To choose the best insulation for your home, you’ll need to consider where you want or need to install the material, the indoor air quality, life cycle costs, recycled content, and ease of installation.³

Most people use fiberglass batt insulation for their attics because it’s affordable and relatively easy to install. With this type of insulation, you must pay close attention to the R-value: its ability to resist heat flow.¹ The higher the R-value, the greater the effectiveness. The R-value is determined by the thickness and density of the insulating material, as well as temperature, aging, compression, and moisture content.³

The amount of insulation or R-value you will need depends on: 

• The climate where your home is located
• The type of heating and cooling system in your home
• The part of the house you’re insulating

For example, the R-value required for an attic in Zone 1, which includes the southern tip of Florida, Hawaii, Guam, Puerto Rico, and the Virgin Islands, is R30-R49. 

However, for an attic in Zone 5, which includes Massachusetts, Rhode Island, and Connecticut, R49-R60 is needed. 

To determine exactly what is required for your home, consult an insulation contractor.

Mistake #2: Neglecting to Seal Air Leaks

Insulation is a protective barrier that slows the rate at which heat enters or leaves your home.

But the insulation that you use is only half of the equation.

To prevent air movement between unconditioned and conditioned spaces, you’ll also need to seal:

• Outer walls
• Windows
• Doors
• Floors

Over time, air and thermal leaks can seriously impact your home’s air quality by allowing in pollutants such as dust, dirt, mold, and mildew. Insulating your attic can prevent these pollutants from entering the interior spaces of your home, allowing your family to breathe easier.

Choose the right product depending on the type of air leak:¹

• Caulk, expanding foam, or weather-stripping can fill smaller holes and cracks
• Plywood, drywall, or rigid foam insulation are ideal for covering larger holes
• Sheet metal and high-temperature caulk can close gaps around furnace flues and chimneys

Mistake #3: Blocking Air Flow

Ventilation is important in an attic. It’s critical to know where to seal gaps but also which places need to remain uncovered, as you don’t want to obstruct airflow. 

Many homes have soffits or eave vents that are designed to allow air to pass through the attic. This airflow prevents humidity issues and also extends the life of the roof.

Make sure not to cover these vents with insulation in order to prevent condensation and mold growth, which can destroy the effectiveness of the insulation and cause health problems.

Mistake #4: Pulling Out Old Insulation

Many homeowners begin by immediately removing old insulation. While this would seem like the logical thing to do, it can make a huge mess and may not ultimately be necessary.

Conversely, if the insulation is soiled with mold or mildew, or rodent droppings, and then carried through the house, it can expose family members to these toxins.

Before you begin pulling out what’s already there, it’s important to keep a few things in mind:

• The age of your home – In the 1950s and 60s, asbestos was commonly used in insulation. Asbestos is fine if left alone, but if agitated, the fibers released into the air can be extremely hazardous, especially if inhaled. Be sure to do your research and take the proper precautions to protect yourself and your family members.
• Assess existing materials – If there’s no asbestos risk, then the old insulation in your home may not need to be removed. Layers of insulation work in a similar fashion as layers of a blanket. You might just need to add some new insulation on top of the old layer to attain the appropriate R-value for your climate.
• Condition of old insulation – If there is evidence of moisture damage, such as from a roof leak, mold, or rodent activity, then the existing insulation should definitely be removed. Be sure to check each section thoroughly and replace it as needed.

Mistake #5: Overstuffing

When it comes to insulation, you might guess that the more you have, the better. 

But in reality, there can be too much of a good thing.

Fiberglass insulation is exactly that—glass that is blown into fibers.³ It has an almost magical quality to keep spaces warm in the winter and cool in the summer. But fiberglass insulation works by catching air between the layers of spun glass. If you pack too much into any given section, the air pockets will compress and the insulation won’t be as effective.

Mistake #6: Not Enough Material

The most common mistake when installing attic insulation is not being thorough enough.

It might sound easy to put up a few batts of insulation, but doing the job right takes time and precision. 

For a successful insulation installation , you should:

• Take appropriate measurements and install just the right amount.
• Cut the fiberglass to fit around any bracing, ducts, electrical, wiring, and pipes.
• Wear the proper protective gear. Fit batts or rolls snugly together to avoid gaps or spacing.
• Work it around any obstacles or tight corners.
• Keep it at least 3 inches away from any recessed lighting fixtures to avoid excess heat or fire.⁴

You may also want to install rafter vents at the soffits to prevent the insulation from covering the attic ventilation and allowing moisture to build up.
