What Certifications the Right Spray Foam Insulation Company Should Have

Just like any company you hire to provide a professional service, it is important that the spray foam insulation contractor you choose for your insulation installation has the right qualifications for the job. You may not know off the top of your head what certifications you should be looking for in that arena, and that’s okay. However, it is in your best interest to learn which qualifications to check for and why each one is important in the grand scheme of your home improvement project. We’re going to give you an overview of the main three to look for.

 

Does the Contractor Use Products Approved by the American Chemistry Council Spray Foam Coalition?

One of the first and foremost factors you should take into consideration is the quality and safety standard of the equipment and products that are going to be used to insulate your home. The American Chemistry Council has several divisions under its Center for the Polyurethanes Industry (CPI) that are devoted to spray foam insulation. The Spray Foam Coalition (SFC) is one of these organizations and it focuses on promoting the benefits of spray foam insulation as well as the importance of safe manufacturing, transporting, and application of spray foam insulation.

Members of the the SFC are companies that are verified and able to produce and sell spray foam insulation systems, equipment, and chemicals according to regulation. You should make sure that any contractor you’re considering is using products from an SFC certified member. A full list of SFC members can be found on the SFC’s website.

Many spray foam companies will have information on what equipment and supplies they use right on their website, but if you can’t find that information on their site you can always ask them yourself. This is important to you because you won’t have to wonder about the quality or safety of the products being applied in your home or the spray systems being used to apply them because you will know that the materials are up to regulation standards.

 

SPFA PCP certification

The Spray Polyurethane Foam Alliance (SPFA) is another part of the American Chemistry Council’s Center for the Polyurethanes Industry. Its Professional Certification Program (PCP) is a multi-level certification program focused on creating the highest standards of installation quality and safety. The different levels of certification are available for assistants, installers, master installers, and project managers. The PCP includes completion of the pivotal Chemical Health and Safety program by the CPI and also covers CPR, first aid, and OSHA safety courses as well.

Once a spray foam installer is certified, two things happen. The first is that they receive a SPFA PCP identification card based on the level of certification they completed. This must be renewed every five years, so be sure to check the contractor’s card is up to date.

The second thing a contractor gets is a CPI Chemical Health and Safety Training ID number. Feel free to ask your spray foam contractor in consideration for this number, and check it to verify completion, using the database here. Completion of this course and certification by the SPFA ensures that the most thorough safety protocol will be followed by the technicians installing your insulation.

 

ABAA certification

Another helpful certification for contractors to have under their belt is the Spray Polyurethane Foam Installer Training Course provided by the Air Barrier Association of America(ABAA). This course focuses on the necessity and function of air barrier assembly, proper installation procedures, codes, and standards.

In order for a contractor to be granted certification, they also must have 3000 hours of experience with air barrier application or other required fields, which includes at least 1500 hours specifically dedicated to spray polyurethane foam experience. This means that if a contractor you’re considering has the ABAA certification, it is a good indicator of having sufficient experience in the field. As discussed in the last section, plenty of experience should be a reassuring indicator that the contractor is an expert at the best practices for installation.

The importance of making sure the contractor you choose is a spray foam insulation expert is an easy task if you ensure that they have the right qualifications. Checking that your installer has obtained these certifications should make you feel more comfortable with the level of safety and precision they will have when applying spray foam insulation in your home.

What Information to Provide Your Spray Foam Installer to Get An Accurate Insulation Estimate

Once you have decided to move forward with your home improvement project of having spray foam insulation professionally installed, the next step is to do your research on spray foam insulation companies in your area and get quotes. Getting things right for this step is so important. Not only will getting estimates from several contractors give you a realistic range of how much your project will cost, it will also give you a heads up of what to expect throughout the process, as most spray foam insulation contractors will want to discuss general timelines and how they will handle the logistics of the application process. Here are some key factors that you should keep in mind when getting a contractor’s quote on your home’s insulation installation.

 

Location

Chances are you already know which part or parts of your home you want to insulate.  It makes a big difference whether it is the attic, basement, crawlspace, walls, or whole house that you want improved. This is most likely the first question a contractor will have for you so that they can determine which type of spray foam insulation and application (i.e. open cell or closed cell, high or low pressure) would be best suited for your project. Each type varies the overall cost of the project, so it is crucial to determine which one is going to be applied in order to proceed with calculating your estimate.

 

Board Footage

A board foot is a unit of measurement of volume, usually in context of construction. The measurement of one board foot is 12 inches length by 12 inches width by 1 inch depth (12”x12”x1”). Cost per board foot, though variable from one company to the next in terms of price of materials, is always a key factor in calculating an estimate. If you can calculate the board footage of the space you are needing insulated, it will save you time right off the bat when getting a quote because this is one of the first questions a contractor will ask. Don’t worry if you can’t calculate this yourself though, because most contractors can easily do that for you as long as you know the basic measurements. Some companies even prefer to get the measurements themselves in order to provide the most accurate estimate.

 

R-value

You may not necessarily need to know the specific r-value you will need. Any contractor can determine your recommended insulation r-value based on your climate and area of the house you are having insulation installed. However, knowing the recommended r-value already will help you understand what information the contractors you speak to are using to calculate the most accurate quote, as well as weed out any vast inconsistencies. You can read our easy step by step guide to calculating your r-value for reference.

A professional contractor will always be concerned with r-value, but some may try to tell you a much higher r-value than is actually needed in order to increase the price of application. On the other hand, some may give artificially low recommended r-values in order to cut corners or seem more budget-friendly. The important thing to remember in terms of r-value is that if it is not up to what it needs to be, you will be missing out on the incredible energy-efficiency, long term savings, and other benefits of spray foam insulation.

 

Budget

If you hadn’t already estimated what your budget should be for the project, it is not a bad idea to use a cost estimation calculator before you even contact any contractors. This should give you a generalized idea of how much you should plan to expense for. A good example of a spray foam insulation cost calculator can be found here. These calculators shouldn’t take the place of comparing specified costs given to you by professionals. A calculator won’t take into consideration any variables that may be part of your project. Some of these variables include recommended r-value, budget restrictions, type of spray foam, and any specific conditions of your house that may affect application.

 

How to analyze the quotes that come back

Unless you are talking about completely different projects in completely different locations of your house, the estimates you receive from different companies shouldn’t vary greatly. Beware especially when it comes to significantly lower quotes. They may have left out an important factor and therefore not have given you the most accurate estimate, which could change drastically once the project is underway. Alternatively, they may  be lowering their normal price in order the try to push old or lower quality materials out of their inventory.

A lower estimate is not always be a bad sign, either. Some of the best contractors may build rapport with you, get an idea of your budget restrictions and work to give you the most competitive rate in accordance with what is best for your home.

By the end of collecting quotes, not only should you have a good idea of which estimates are the most accurate and realistic, it should have also given you the prime opportunity to check the qualifications and certifications of each installer you spoke with. Your cost comparison along with getting to know more about the companies individually will set you on the right track to hire the best and most qualified contractor for your spray foam insulation project without any major surprises later!

DIY Spray Foam Insulation vs. Professional Installation

Anyone who has looked into spray foam insulation knows that as a general rule of thumb, there’s not really such thing as do-it-yourself (DIY) spray foam insulation. If you have decided to insulate your home with spray foam and are looking for the next right steps to start your project, you may still be trying to find a way to make it work as a DIY project. Common reasons for trying to do things alone include trying to save money or avoid the hassle of finding the right contractor. Sometimes a homeowner is just more of a hands-on home improvement person in the first place, and accustomed to handling projects with ease. If you are harboring any doubts whether installing spray foam insulation is really as complicated as contractors say it is, rest assured., In most cases, spray foam insulation technicians aren’t just conveying the idea that DIY is a bad option in an effort to gain more business for themselves. Ethical installers care that things are done safely and effectively and seek to underscore the many reasons why installing spray foam in your house is best left to spray foam insulation experts.

The first and most obvious reason is because of the specialized equipment systems needed for application. Even the oversimplified DIY spray foam insulation kits you can purchase at a home improvement store near you require very specific processes in order to function properly when applying spray foam to even the smallest areas. Although they are already intended for small projects, the most common complaints made by consumers who try to use these kits are that they cover much less square footage and thickness than advertised, and that the mess caused by faulty hoses and broken tips is not worth the hassle. This means in order to finish your entire installation project using  nothing but do-it-yourself kits, you would probably end up spending just as much money and many more hours than that of having it installed by a professional.

Professional rigs like the ones used by contractors can handle much higher application demands, but are impractical to purchase for single project use. They would cost you literally tens of thousands of dollars more than just hiring a contractor to complete your project. There would be absolutely no reason to purchase a professional spray foam system unless you yourself are looking to get in the business of spray foam installation!

Having technical issues with equipment isn’t the only way to end up with a mess on your hands. The spray foam insulation application process can be a messy one. Think about it: A pressurized machine is being used to spray liquids that quickly turn into foam onto a surface that is most likely indoors. Unless you know the proper procedures and techniques to follow for the most precise application, there will be quite a bit of fallout. Luckily, certified spray foam insulation contractors have been trained on these techniques to eliminate as much mess or waste of supplies as possible. Not to mention, precision spray foam insulation installation ensures there are no holes or gaps overlooked that could result in air infiltration and weaken your home’s energy efficiency.

The last and possibly most important reason to leave your spray foam project to a professional is due to crucial safety concerns. There are particular specifications on how the equipment and chemical compounds used in the application process for closed cell foam must be handled in order to ensure the health and safety of both the installers and homeowners. Professional installers go through training and certification courses on chemical safety to be equipped with the safest application procedures to follow as well as what to do should a first aid situation arise. This should give you more peace of mind that a certified contractor completing the job will follow proper protocol and not unknowingly compromise the health of you or your loved ones by improperly handling products during application.

As you now see, there are several very important points to dissuade you from attempting to make insulating your home with spray foam a DIY project. Spray foam insulation is a fantastic investment for your home, so there is no reason to compromise its value or effectiveness. A certified professional will be able to complete your spray foam insulation in the most cost effective way and the least amount of time without compromising precision or safety.

The Pros and Cons of Closed Cell Foam Insulation

If you’re considering spray foam insulation for your home, and aren’t sure whether it’s the right choice, it is important to consider what is most important to you. The best choice for your insulation project boils down to deciding whether it is more important to save some money now, or save far more in the long run.

Making your choice becomes easier when you consider the pros and cons of closed cell spray foam insulation. The focus of this post is closed cell spray foam as opposed to open cell foam because it is the most energy efficient and most commonly used type.

Cons

Spray foam is impractical as a DIY project

• Installation of spray foam insulation requires expensive, specialized, and difficult to use spray equipment and processes.
• The installation process can also be messier than installing other insulations. Avoiding unwanted mess can be complicated if you’re unsure how to protect the area that you’re working in and how to handle clean up once the job is done.

It’s worth nothing that no matter what material you choose, installing insulation in your home is not a matter to be taken lightly. Without adequate previous experience installing insulation, there is more room for error, injury, and poor results when important steps are inadvertently overlooked. As a general rule of thumb, installing insulation is best left to the certified professionals who are spray foam insulation experts.

More expensive upfront cost

• The cost of installing spray foam insulation is generally 2-3 times more expensive upfront than traditional fiberglass insulation.

This cost difference is mainly due to the need for professional installation, which many people opt for anyway even when choosing traditional fiberglass insulation. It’s also important to balance the installation cost with the fact that it only takes on average of 2-4 years before the benefit of energy bill savings outweighs the cost difference between spray foam insulation and cheaper insulation like fiberglass. Every year past that point is just money in your pocket. Looking into the future even further, you avoid the significant cost of needing to replace cheap insulation as early as 10 years down the line.

Pros

Spray foam is the most energy efficient insulator

• Because it expands, spray foam fills in gaps and holes other types of insulation can’t and creates an efficient, airtight seal.
• Spray foam’s insulation r value (resistance value) is 6.0-6.5, one of the highest values available on the market.
• Unlike other insulation materials, spray foam’s r value remains stable over time.
• These resistant properties result in a thermal envelope, causing more consistent in-home temperatures.
• Homes with spray foam insulation have lower HVAC system capacity requirements (meaning your air conditioner and furnace don’t have to work as hard to reach a comfortable temperature).

The net effect of all of these properties is that spray foam insulation is highly energy efficient, stays that way long-term, and results in significant energy bill savings.

Spray foam is not only airtight but is also water-tight

• Closed cell spray foam does not absorb water or moisture. Other insulation materials do!
• FEMA has classified spray foam as highly resistant to floodwater damage
• Even after flooding and/or exposure to water, spray foam insulation can be cleaned of most pollutants. This is not possible with most other materials.
• Mold and mildew cannot feed or thrive off of spray foam’s inert polymer composition, making it a mold deterrent
• Spray foam’s airtight properties reduce the infiltration of allergens like pollen and dust

Spray foam’s airtight, cleanable, mold resistant properties create healthier air quality when professionally installed in homes. If you have allergies or live in flood-prone areas, spray foam is an especially great way to improve your comfort, health, and peace of mind at home.

Indefinite lifespan

• Spray foam insulation, once installed, is structurally permanent and will not settle or break down.
• Unlike any other materials, spray foam actually adds structural strength to a building’s walls!

As we mentioned earlier, traditional materials like fiberglass settle and shift over time. To remain effective, fiberglass sometimes has to be completely re-done as soon as ten years after installation. Spray foam insulation doesn’t.

Looking for an Insulation Calculator? Here Are the Important Factors to Consider

Figuring out the cost and other details of an insulation project is difficult. Knowing where to start, and how to discern quality information online will help immensely. Unfortunately, Googling things like “insulation calculator” results in a flood of all sorts of calculators from various sources. It can be overwhelming to sift through, and a majority of top results are geared specifically toward problematic approaches like outdated fiberglass insulation for home improvement projects. If you don’t yet know whether or not you’ll even go with fiberglass, let alone details like how many rolls you might need, these calculators are often not helpful to at all. Let’s take a look at the two most helpful factors that you should focus on at this stage:

• R-value comparison
• Cost comparison

Comparing Insulation R-Values

When comparing the r-value of different insulation types and how installing them will affect your home, you need to consider a combination of factors and their potential benefits. The creators of most insulation r-value calculators are either hardware stores or insulation manufacturing companies. This means they usually only calculate the insulation needed for their own brand. They will usually provide limited results outlining their products’ estimated performance if it were installed in the location and dimensions of your home. For someone just starting their research, these calculators ask the wrong questions, are biased, and aren’t very helpful. 

There’s a better way to calculate meaningful answers. You will need to gather some data first. We have broken down everything you need to know into three steps. Each is explained below. By the time you’re done, you’ll have a strong set of answers, based on real data, about any type of insulation you’re considering.

We have relied on recommendations and data from the U.S. Department of Energy throughout. They are a great resource, especially for the first two steps of the process.

Step One: Find your R-Value by Climate Zone

First, you will need to find the number for your r-value climate zone, which can be located using the following map from the Department of Energy:

For example, if you live in Boulder, CO, you would be classified as climate zone 5.

Step Two: Match your Climate Zone Number to the D.O.E. Recommended R-values

Next, you would match your climate zone with a table outlining recommended r-values by climate zone, using this table (also from the Department of Energy):

 

Suggested R-Value by Climate Zone
Location	Heat Type	Attic	Wall	Floor	Crawl Space	Basement Wall
Zone 1	Natural Gas	38-49	13	13	13	11
	Oil Furnace	38-49	13	13	13	11
	Electric Furnace	38-49	13	13	13	11
	Electric Baseboard	38-49	13	13	13	11
	Heat Pump	38-49	13	13	13	11
	LPG Furnace	38-49	13	13	13	11
Zone 2	Natural Gas	38	13	13-19	13	11
	Oil Furnace	38	13	13-19	13-25	11
	Electric Furnace	38-49	13	19-25	25	11
	Electric Baseboard	38-49	13	13-25	13-25	11
	Heat Pump	38	13	13-19	13	11
	LPG Furnace	38-49	13	19-30	25	11
Zone 3	Natural Gas	30-38	13	13-19	13-25	11
	Oil Furnace	38	13	13-19	13	11
	Electric Furnace	38	13	13-19	13-25	11
	Electric Baseboard	38	13	13-19	13	11
	Heat Pump	30-38	13	13	13	11
	LPG Furnace	38-49	13	13-30	13-25	11
Zone 4	Natural Gas	38-49	13	25-30	25	11
	Oil Furnace	49	13	30	25	11
	Electric Furnace	38-49	13	25-30	25	25
	Electric Baseboard	49	13	30	25	11
	Heat Pump	38-49	13	13-25	13-25	11
	LPG Furnace	49	13	30	25	11-25
Zone 5	Natural Gas	38	13	25	25	11
	Oil Furnace	49	13	30	25	11-15
	Electric Furnace	49	13	30	25	25
	Electric Baseboard	49	13	30	25	11
	Heat Pump	38	13	30	25	11
	LPG Furnace	49	13	30	25	25
Zone 6-8	Natural Gas	49	13	30	25	25
	Oil Furnace	49	13	30	25	25
	Electric Furnace	49	13	30	25	25
	Electric Baseboard	49	13	30	25	25
	Heat Pump	49	13	30	25	25
	LPG Furnace	49	13	30	25	25

So for example: If you are located in Zone 5 of the climate zone chart, you would find Zone 5 on the suggested r-values chart. From there you would be able to further determine what r-value is needed based on the heat type of your home and which area you are looking to insulate. If you’re looking for the best way to insulate the attic of an electric furnace heated home in Zone 5, an r-value of 49 is recommended.

Step 3: Calculate the Thickness of Insulation Needed

The last step, which does require light calculation, is to determine what thickness of each type of insulation you would need.

To perform your calculation, you’ll need to find the r-value per inch for every insulation type you are considering. Most of the relevant types and their associated r-value/inch are listed in the following table:

 

Insulation Type R-Values by Application
Material	R-Value/inch
Closed-cell Spray Foam	6.0 – 6.5
Open-cell Spray Foam	3.5 – 3.6
Polyisocyanurate Board (foil-faced)	5.6 – 8.0
Polyurethane Board	5.5 – 6.5
Polystyrene Board	3.8 – 5.0
Blown-in Cellulose (attic)	3.2 – 3.7
Blown-in Cellulose (wall)	3.8 – 3.9
Blown-in Mineral Wool (attic)	3.1 – 4.0
Blown-in Mineral Wool (wall)	3.1 – 4.0
Mineral Wool (batt)	3.1 – 3.4
Blown-in Fiberglass (attic)	2.2 – 4.3
Blown-in Fiberglass (wall)	3.7 – 4.3
Fiberglass (batt)	3.1 – 3.4

The calculation required by you is simple: Divide your recommended r-value by the r-value per inch of each of the insulation types you are comparing. Continuing with the previous example, the attic of a Zone 5 electric furnace heated home is recommended to be insulated at an r-value of 49. This means your attic would require around 11.4 to 22.3 inches of blown-in fiberglass insulation to be at the recommended level of energy efficiency. In comparison, the same attic would only require about 7.5 to 8.2 inches of spray foam insulation to meet the same energy efficiency standard. It quickly becomes evident how big of a difference this can make! It may not be practical, or even be possible to attain your recommended r-value with certain forms of insulation if they can’t be applied or layered that thick. This would result in significant energy loss over time.

Comparing Cost

The second critical factor to consider is the comparison of various types of insulation’s upfront installation costs and cost over time. This is many people’s primary concern. Luckily, there are calculators available that will use the square footage of your home to estimate your upfront installation costs of each type of insulation, the cost of your monthly energy bills after installing said insulation, and the potential savings or loss over time. Many of these cost estimators focus on comparing various forms of insulation vs. fiberglass. This is because fiberglass is the most common material used to insulate homes. Fiberglass is also one of the least efficient insulators available on the market.

Here is a simple calculator that compares fiberglass and spray foam insulation. The cost difference over time in comparison to upfront cost is astonishing. Although installing spray foam insulation is up to three times more expensive than installing fiberglass, that cost difference usually is surpassed by energy savings within less than 4 years. And past the point that the benefits outweigh the extra upfront costs, the lower energy bills from having your home more efficiently insulated will continue to add up.

Comparing Added Equity to Your Home

Another factor that you may be looking for a calculator for is the comparison of how much market value the different insulation types add to your home. Unfortunately, there is no one size fits all comparison tool to find the best insulation. There’s no question that adding insulation to your home, no matter what type, automatically adds value. However, once you’ve done your research and calculations for the first two factors, you don’t even need a calculator to estimate which types of insulation would add the most value to your home. When searching for said calculator, you will come across many different sources that give you the same general rule of thumb: The higher r-value your insulation has, the more energy efficient your home will be. And the more energy efficient your home is, the higher value it will have.

Whichever option was the clearest when comparing r-value and cost effectiveness will more than likely be the best choice in terms of adding equity to your home. In our examples and across the board, spray foam insulation had the highest r-value per inch as well as the highest projected energy bill savings over time, making it the clear choice for the best investment to not only save you money per month but also add value to your home if you are looking to put it on the market in the future.

The True Cost of Cheap Insulation

When you hear the word insulation, the first thing that probably comes to mind is the fluffy pink batts of fiberglass you see lined up in every hardware store or when you peek into old attics. These rolls and batts may even be the first solution you think of when it comes to considering an insulation solution for your home, whether building a new home or replacing old insulation. It’s in your best interest to think again.

Yes, fiberglass is a quick fix for your insulation problem. Yes, it has one of the cheapest upfront material costs . And yes, installing fiberglass batts can even be a relatively simple do-it-yourself project. All of those “advantages” really just equate to short-term convenience. There are many more disadvantages over time that you should be aware of. This begs the question, is the convenience really worth it? What is the true cost of choosing cheap insulation?

First of all, the main purpose of insulating a building is to more efficiently regulate the internal temperature. This is achieved by resisting the infiltration of outside air or preventing the leaking of climate controlled air from inside your home. The measure of an insulating material’s ability to resist this air infiltration is called the resistance value, or r-value. Fiberglass insulation, in all forms, has some of the lowest r-values of the most commonly used insulation types. Take a look at this comparison of r-value by insulation type:

Insulation Type R-Values by Application
Material	R-Value/inch
Closed-cell Spray Foam	6.0 – 6.5
Open-cell Spray Foam	3.5 – 3.6
Polyisocyanurate Board (foil-faced)	5.6 – 8.0
Polyurethane Board	5.5 – 6.5
Polystyrene Board	3.8 – 5.0
Blown-in Cellulose (attic)	3.2 – 3.7
Blown-in Cellulose (wall)	3.8 – 3.9
Blown-in Mineral Wool (attic)	3.1 – 4.0
Blown-in Mineral Wool (wall)	3.1 – 4.0
Mineral Wool (batt)	3.1 – 3.4
Blown-in Fiberglass (attic)	2.2 – 4.3
Blown-in Fiberglass (wall)	3.7 – 4.3
Fiberglass (batt)	3.1 – 3.4

 

There are two reasons why fiberglass insulation along with other batt insulations like mineral wool have such low r-values in comparison to spray foam insulation and even foam board. The first is the structure of the material itself. Fluffy wool or felt slows the transfer of air and temperature through walls and roofs but does not block it completely.

The second and possibly less obvious reason fiberglass and wool insulation has a low r-value is that the lack of precision during installation. In other words, the material is unable to seal off any spaces, gaps, and holes completely. These seemingly minor gaps that are left unsealed play a major part in a home’s energy efficiency loss and make your residential HVAC system work at a higher capacity than it needs to. Not only are they responsible for the loss of energy, but also allow for the infiltration of pests and airborne allergens. The most foolproof solution against these infiltrations is to have spray foam insulation professionally installed. Spray foam expands and fills in every crack, creating an airtight seal within your home and lowering your HVAC system’s workload.

When it comes to the question of whether fiberglass really is cheaper, only doing an upfront cost comparison will cost you more in the long run. The convenience factors of fiberglass, like the lower cost of materials and the ability to install it yourself, are considerably short-sighted when compared to the advantages of newer forms of insulation like closed cell spray foam. Compare fiberglass’ misleading “advantages” to its low r-value, resulting energy loss, and high HVAC workload. These all equate to year-round higher energy bills. Higher bills month after month will quickly chip away at the amount you “saved” by going with a cheap material. In 2-4 years you’ll face a significant loss versus what you would have saved by insulating with advanced materials from the start. The savings on your energy bills by using spray foam insulation, which can easily be calculated, would continue to add up for years to come after the cost gap has closed.

On top of the post-installation financial loss over time, cheap insulation does not have as long of a lifespan when compared to newer approaches like spray foam insulation. It takes about 10 to 20 years on average for fiberglass to settle, collect dust, and harbor pests. After this point, it’s time to replace your insulation yet again. This timeline is dramatically shorter if your fiberglass insulation is exposed to moisture damage before its natural replacement point. Both fiberglass and cellulose insulations retain water, which can quickly lead to the growth of mold within your walls. Closed cell spray foam insulation has an indefinite lifespan and is completely water resistant, so unlike with fiberglass or any insulation material that breaks down and settles, you wouldn’t have to reach out of pocket to replace your insulation again.
