Spray foam insulation is a high-performance energy-saving home upgrade that can be applied to new and existing structures. It acts as both insulation and a sealant, closing the nooks and crannies that let air escape and drive up energy bills. It also creates a healthy barrier, reducing sources of mold and allergens that cause runny noses and itchy eyes.

It offers a higher R-Value than spray foam insulation and cellulose insulation—typically between R-3.5 and R-6.5 per inch of thickness (open cell) and R-6 to R-7 per inch of thickness (closed-cell). It’s an excellent choice for reducing energy bills in both new and old homes.

A benefit of spray foam is that it doesn’t deteriorate over time like fiberglass and cellulose. It is also not prone to sagging or swelling. It’s not difficult to apply, although most homeowners prefer to hire a professional insulation contractor. A professional can quickly and neatly complete the job, and they can ensure that their work meets all necessary building codes.

Another advantage of spray foam is that it doesn’t contain harmful fiberglass fragments that can be ingested by children and pets. It’s also non-toxic, mold-resistant and fire-retardant. Spray foam does have one concern: the blowing agent used in most spray foam products has a global warming potential (GWP) of over 3,400 times that of carbon dioxide on a per-kilo basis. Some companies have switched to using low GWP blowing agents, however, and it’s important to ask about the type of spray foam you’re buying.
