What is spray foam insulation? Spray foam insulation works as an air barrier material that seals walls, floors and ceiling cavities against air movement. This includes spaces around electrical outlets and light fixtures, and also where walls meet windows and doors. Spray foam can be sprayed into an open cavity, like in new construction, crawl spaces, attics and more.

When should spray foam insulation be used? Many newer homes these days are insulating their newly built homes with spray foam insulation for energy efficiency as well as comfort benefits. And, homeowners of existing homes are deciding to retrofit their attics, walls, and crawl spaces with spray foam to fix uncomfortable room issues as well as to save money on monthly energy bills.

Another great thing about spray foam insulation is that it never loses its shape. Unlike conventional insulation materials, spray foam fills cracks, gaps and crevices on installation. It won’t compress, sag or settle over time.

And, because spray foam insulation fits so well into every nook and cranny, closed cell spray foam insulation also allows very little moisture into your home; this also means that dust and other allergens are less likely to enter your home too. This could lead to better health for you and your family, especially for those who have allergies. Closed cell spray foam insulation is also a great way to help reduce the amount of outside noise that enters your home. This is especially beneficial for those who live near a busy road or a similar area.

Closed cell spray foam insulation can even help improve your home’s structural integrity as well as help keep out birds, insects, squirrels and other critters from nesting in your home. In the long run, this could help you avoid pests like termites, which could cause a great deal of damage and require expensive repairs.

What is spray foam insulation made of? When most spray foam insulations are made, two liquids combine causing a chemical reaction to form the spray polyurethane foam.
