USA Insulation Frequently Asked Questions

This page contains answers to some of the top questions we receive about home insulation. Here at USA Insulation, we’re all about education, information, and knowledge. That’s why we take the time to make sure that our clients have access to the answers and resources they need! If you have questions, here’s a good place to start.

General Insulation Questions

What does retrofit insulation mean?

Retrofit insulation simply means insulation applied to existing structures, as opposed to installing insulation during the initial construction process when a home is being built. Even if your home already has some insulation, our highly skilled team can vastly improve the insulation of your home with our superior products and application techniques. This is especially true for homes built before 1980 before there were building codes dictating insulation minimums.

What is R-Value?

R-Value measures the insulating power of a material or product. The “R” stands for “resistance” and the higher the R-Value is, the more resistant the insulation product will be to heat flow, creating an effective thermal barrier. Visit Understanding R-Value for more information.

USA Premium Foam® Questions

How can USA Premium Foam help my indoor air quality?

As a complete thermal barrier, USA Premium Foam efficiency blocks leaks and protects your home’s air quality by keeping out dust, pollen, and other contaminants. As a result, it helps prevent allergy and asthma attacks while keeping your home comfortable and free from drafts.  You can also rest easy knowing that as an inert product, it does not release loose fibers or clumps.

What is involved in the installation process?

The foam is applied to an existing wall cavity using our proprietary insulation equipment designed specifically for our foam. The applicator is inserted into the wall through small holes carefully drilled in the siding or mortar. We then cover these holes post-application for a seamless surface. Read more about the installation process.

Is USA Premium Foam a fire hazard?

No. USA Premium Foam Insulation has undergone testing from some of the most stringent and respected independent laboratories in the United States. According to the strict guidelines outlined in ASTM E-84 testing, USA Premium Foam has a Class A rating. This is the best rating available for Interior Wall & Ceiling Finish products with a Flame Spread rate as low as 5 and a Smoke Spread rating of 10. Other insulation products can release hazardous gases in a fire, or may even pose a fire or smoke risk. Additionally, the ASTM E-119 – Standard Test Method for Fire Tests of Building Construction and Materials, showed that USA Premium Foam Insulation held strong for more than two hours! In fact, it is the only insulation that actually increases fire ratings on non-compliant buildings!

How long will insulation installation take?

In most cases, we can complete the entire installation process in one day!

Will USA Premium Foam create a pest or bacteria problem?

No. USA Premium Foam is made without chemically treated fibers or loose materials that could attract rodents, insects and other pests. In fact, it’s excellent at keeping pests out of your home by sealing wall cavities. And as an inert substance, it does not sustain any kind of mold, bacterial, or fungal growth.

Can I purchase USA Premium Foam and install it myself?

Unfortunately, no. The application process requires highly-specialized equipment and trained installation experts all of which are exclusive to USA Insulation. We encourage you to call your local USA Insulation office to receive a no-obligation, complimentary price quote.
