What is Spray Foam Insulation?

Last updated 2 years ago

Although fiberglass has been the industry standard for home insulation for several decades, there are now many other materials available that are far more effective at sealing the home and preventing heat and moisture transfer. The most well-recognized of these is spray foam insulation. In this post, we’ll take a look at what spray foam insulation is and how it compares to other types of insulation.

How It Works

Spray foam insulation is made from polyurethane, an organic compound that is used in a number of different products, including foams, plastics, and fabrics. Polyurethane foam is actually a combination of two chemicals that are mixed together at the jobsite and then applied directly to the wall frame. These two chemicals react, which makes them expand and harden in the wall or ceiling frame. This allows the insulation to fill in all gaps and cavities in the wall for a perfectly air-tight seal.

Open-Cell vs. Closed-Cell

Spray foam insulation comes in two varieties: closed-cell and open-cell. Closed-cell foam insulation creates a completely air- and moisture-resistant barrier, which gives owners are a higher R-value and greater insulation performance. Open-cell foam insulation is permeable to both air and moisture, and is a great option for homeowners who prefer a less dense insulation option. Open-cell foam insulation will allow your home to “breathe” more, while still providing impressive insulation performance.

Effectiveness of Foam Insulation

When it comes to performance, spray foam insulation is far more effective than any other type of insulation available. In addition to providing better R-values per inch than fiberglass or cellulose insulation, closed-cell foam insulation can also act as a vapor barrier, which blocks out moisture and prevents the growth of mildew and mold in your walls. Spray foam insulation is a great choice for homeowners seeking maximum energy efficiency and greater comfort.
