Closed-Cell Spray Foam

Closed-cell spray foam, also called two-pound residential foam, has excellent insulating properties. It has the highest R-values per inch which range from 7.0 - 7.4. The closed cells in this type of foam insulation provide a barrier against both air and vapor passing through. This makes it very useful in areas in locations where there are extreme weather changes, such as New England.

In addition to resisting both air and vapor passage, closed-cell spray foam actually strengthens the structures where it’s used. This characteristic helps homes resist high winds. In roofing areas, closed-cell spray foam insulation is strong enough to walk on.

Unlike some other types of insulation, closed-cell spray foam will not settle over time. This reduces the likelihood of uninsulated spaces developing over time.
