Frequently Asked Questions

Why Choose American Spray Foam?

All the products on American Spray Foam were manufactured by American facilites, meaning that not only is it the highest quality Spray Foam Material but it is also ensuring the continuation of important American Jobs.

What is the difference between Open and Closed Cell Foam?

Closed-cell foam typically has a higher R-value compared to Open Cell Foam. Closed Cell comes in at around 6.0 per inch sprayed compared to open cell which is closer to 3.7 per inch spayed. That being said, open-cell foam is the perfect choice for interior projects that have difficult to reach areas due to it’s naturally expanding properties.

Do I need to acquire any specific certifications or licenses to spray foam insulation?

No, in the US you do not need any special certifications or licenses to spray foam part-time, this does, however, come with some caveats. For example, many popular Spray Foam Manufactures will want you to be certified with their product in order to avoid any liability issues, this can, of course, be avoided by buying from a licensed distributor, just be sure to check prior to purchasing. It should also be noted that to operate as a business in the US you will need a license to do so. While not required, we do recommend taking safety classes if you’re just getting into the business

How is Spray Foam Insulation different from more traditional forms of insulation?

The main difference between spray foam insulation and more traditional forms of insulation like fiberglass or cellulose is that spray foam insulation is an air barrier and thermal barrier all in one (with closed cell spray foam even offering a moisture barrier as well). This means that spray foam insulation does the job of providing insulation and air sealing with one product, whereas traditional forms of insulation do not provide any barrier to the flow of air. This is important for establishing a continuous and complete thermal/air barrier with the building envelope

What can my residential clients expect after an insulation job?

While actual results can differ, most residential clients can expect to see between 15-40% on their energy bills, increased comfort in their home, soundprofing, and more!

Am I limited to only using foam in residential and commercial settings?

Absolutly not, polyurethane spray foam is particularly valued for use in industrial settings where refridgeration is a concern as well as in agricultural settings.

When should you apply spray foam during construction?

During construction, Spray Polyurethane Foam can be applied at the same time as you would with fiberglass or cellulose foam, i.e. after rough plumbing, heating and air conditioning ducts, and electrical wiring has been installed.

Is there a required thickness of closed cell foam when applied to crawlspaces?

According to the International Energy Concervation Code, an avaerage R-value of 13 is required, however you should always check with your local building code official to be sure.

Is Spray Foam code approved?

Yes, Spray Foam Insulation is approved under the Foam Plastic section, as well as the use of thermal barriers.

When should I use Open Cell vs Closed Cell Insulation?

The general rule to follow is that one should treat open cell foam identically to fiberglass or cellulose. It is an excellent insulator giving the end user a near perfect fit. In doing so, it also creates a nearly perfect air seal (in contrast to fiberglass or cellulose). This air seal is responsible for up to 40% of heating and cooling savings of the house. However, closed cell foam can be used in numerous situations for which there is no other answer. It is intrinsically structural, a vapor barrier, a drainage plain, an air barrier and, of course, perhaps the highest R-Value per inch available on the market (usually around 7 per inch).

What type of equipment do you need to apply foam insulation?

At the very least, we recommend that you have a quality spray foam proportioner system complete with gun, heated hose, and whip; a way to transport the heavy foam barrels to your job site; air compressor; and unless you are planning to run a shorepowered operation (meaning that you're able to connect to the jobsite's powergrid) a generator as well as a reliable way to transport all the heavy machinery.
