What is Spray Foam Insulation?
Spray foam, or SPF, is a spray-applied material widely used to insulate and air-seal buildings, making them more energy-efficient and comfortable. SPF insulation offers excellent thermal performance. Because SPF is air-impermeable, it is a highly effective solution in reducing unwanted air infiltration.
Air sealing a building with SPF is a simple solution to conserve energy, because according to the Department of Energy, as much as 40% of a building's heating and cooling energy may be lost to air infiltration, making energy use unnecessarily high.
Spray foam is unique because it's applied on-site as a liquid, allowing it to form and expand to cover surfaces, creating a seamless barrier that fills gaps, holes, and air leaks. SPF is most commonly used as a wall cavity insulation, an air barrier helping to seal a structure, roofing systems on commercial buildings or residential homes with low-sloped roofs, and a sealant for windows, doors, and other small cracks, gaps, and holes.
SPF is a great product that maximizes thermal efficiency because it can serve as an insulation and an air barrier, keeping a building warm in the winter and cool in the summer.
