Benefits Of Spray Foam Insulation

With some of the highest insulation R-values available, spray foam insulation can improve efficiency and comfort. Spray polyurethane foam (SPF) is a versatile insulation and sealant that can create a continuous air barrier on multiple surfaces in homes or buildings, including ceilings, walls and concrete slabs. Spray polyurethane foam is created by mixing two fast-reacting liquids, isocyanate and polyol resin, that expand to create foam when mixed.

Closed-Cell And Open-Cell

Open-cell foam has a lower R-value per inch than closed-cell, and is typically about 30% less expensive. Due to the lower R-value, open-cell must be applied in a thicker layer. Because of this, it lends itself to areas that offer more space, such as attics, ceilings and floor joists.

Closed-cell foam is more expensive, but that investment pays off in a higher R-value per inch. In addition, because of it's 'sticky' qualities and rigidity once cured, it can also provide increased structural integrity to walls and ceilings.
