Spray foam insulation is a premium product that many homeowners choose for a variety of reasons. It insulates better than fiberglass and cellulose and provides an air seal which can help save on energy bills. It also prevents ice dams by stopping the flow of warm air into the attic space and therefore preventing the formation of ice dams that can cause damage to the roof structure and gutter system.

Closed-cell spray foam is more expansive than open cell, meaning it is able to seal nooks and crannies more effectively. It offers an R-value of 7 per inch, which is higher than other insulators and can lead to major heating and cooling savings. However, closed-cell foam is more expensive than other insulators and can be difficult to install correctly without experience.

Improving Indoor Air Quality with Spray Foam Insulation

Both open and closed-cell spray foams insulate by impacting conduction and convection, which affect the flow of heat in and out of buildings. They both reduce noise, but open-cell spray foam is better at absorbing sounds rather than eliminating them. This is because it is filled with pockets that are more likely to muffle sound than block it.

Both open and closed-cell spray foams can be a green choice for your home, as they are environmentally friendly when used properly. However, if you want to make an even more green choice, we recommend choosing a spray foam containing low GWP blowing agents like HFOs. The HFOs have a much lower GWP than the chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) used in conventional spray foam, and they are also safer for indoor use.
