What is Wall Insulation Foam Injection?

Having a properly insulated home is a must. Without high-quality insulation, your home won’t be able to retain conditioned air, which presents a whole host of problems. Chief among them is unnecessarily high energy bills; the more conditioned air you lose, the harder your HVAC has to work, and the more you’ll have to pay.

While the best-known forms of insulation include fiberglass or cellulose, there’s another form of wall insulation that typically performs even better, with even fewer downsides. That would be foam injection insulation.

Wall injection foam is an excellent option for homeowners looking to retrofit their homes with improved insulation. But what exactly is it? How do you know if it’s the right fit for you? No worries, we’ve done the work for you. Follow along, and we’ll break down everything you need to know about wall insulation foam injection.

What is Wall Injection Foam Insulation?

Injection foam insulation is used on closed wall cavities to retrofit existing homes. USA Premium Foam can be installed from the outside no matter what the exterior surface:

  • Shingle
  • Brick
  • Vinyl siding
  • Block
  • Stucco
  • Aluminum Siding

Benefits of Wall Insulation Foam

So, is wall insulation foam actually better than the alternatives? It depends on your specific situation, but this foam does have significant benefits. The strongest benefits come with USA Insulation’s proprietary USA Premium Foam Insulation, which is used to retrofit existing homes.

R-value—the “R” stands for resistance—is the standard methodology for measuring a property’s insulation value. A normal material will have an R-value between 3.2 and 3.6. USA Premium Foam has an R-Value of 5.1, 35% higher than a standard competitor.

In addition to insulation, USA Premium Foam also acts as a sound barrier, reducing noise both in and out of your home. Further, it works to improve the overall air quality in your home.

While many insulation materials are flammable or release toxic chemicals when heated, USA Premium Foam is actually the opposite. It is flame-retardant and will act as a barrier to fight the spread of flames, in the worst-case scenario of a fire in your home. It also features a best in class fire rating.

Wall Insulation Foam Installation Process

Spray foam can be installed in any open cavity, including attics, wall cavities, rim joists, and crawl spaces. For enclosed cavities in existing walls, you would use injection spray foam.

Both are based on the combination of two different liquids: one aqueous solution, and one catalyst. As the mixture is sprayed, it causes a chemical reaction, leading to the foamy consistency and eventual expansion that covers the treated area.

If you are retrofitting, USA Premium Foam can be installed over old fiberglass or cellulose insulation.
