Proper insulation makes your home more comfortable, reduces the wear on HVAC equipment, and can even lower your energy bills. However, you must choose the best possible insulation product for the top results. Spray foam insulation is an advanced solution that has much to offer homeowners, as illustrated below. 

Frequently Asked Questions About Spray Foam Insulation for Homes

How is spray foam different from fiberglass insulation?

Unlike fiberglass insulation, which must be nailed or otherwise fastened to walls, spray foam is made from a special formula that expands wherever it’s applied. This allows it to reach cracks and crevices that conventional insulation would be unable to cover. Spray foam also creates a barrier against air and moisture, while fiberglass insulation does not. 

What does R-value mean?

R-value is a measurement of an insulating material’s heat resistance. Many different factors go into R-value calculations, including how thick the material is and its weight per square foot. Spray foam insulation typically has a much better R-value as compared to fiberglass, with foam products being rated as 3.6 to 8.2, while fiberglass falls between 2.2 and 2.9.

What’s the difference between closed-cell and open-cell spray foam?

Closed-cell foam insulating sprays are known for their high R-values due to their chemical makeup. Cells, or bubbles, in the foam are completely encased. That makes the closed-cell foam more rigid, as well as being resistant to air and water intrusion. Open-cell also creates a barrier against air and even has soundproofing qualities. While it has a lower density due to open-cell configuration, which means air bubbles are not fully encased, it still offers a very favorable R-value. It can also expand in hard-to-reach places since it’s much less rigid. 

How long does spray foam last once installed?

Spray foam insulation is well-known for its longevity. Most applications are projected to last 30 years or longer, depending on where foam is applied. The foam that’s exposed to the elements may have a shorter lifespan. That makes it a great investment for your home, as you’ll continue reaping the benefits for many years to come.
