Many homeowners ask us at South Central Services, “What is spray foam spray foam insulation?” This is a great question because spray foam is a relatively new form of home insulation. In simple terms, it’s a type of plastic foam that is sprayed in place and it expands to fill the space. It is an excellent insulator that provides better coverage than fiberglass batts or rigid foam.

Spray foam is also a more effective energy-efficient option than traditional fiberglass insulation. Compared to fiberglass, spray foam has a higher R-value per inch. R-value is the measure of how well a product resists heat flow in or out of a room. R-value is important for keeping a house warm in the winter and cool in the summer.

Both open and closed-cell spray polyurethane foam are a good choice for insulation in a building. Both start as liquid chemicals and undergo a chemical reaction to create the foam insulation. Closed-cell foam starts as isocyanate and polyol blends that are purchased by professional contractors and then mixed together with a spray gun.

Eco-Friendly Benefits of Using Spray Foam Insulation

The foam is sprayed onto open cavities such as attics, crawl spaces, and rim joists in existing homes or into unfinished walls of new construction. It can also be sprayed into wall cavities in commercial buildings or pole barns.

When sprayed, the foam forms little pockets that provide barriers for air and heat, which helps to maintain the R-value of the wall. It is very durable and doesn’t sag or lose its shape over time. The foam is water-resistant and will not promote mold or mildew.
