Spray foam insulation is an alternative to traditional building insulation such as fiberglass. A two-component mixture composed of isocyanate and polyol resin comes together at the tip of a gun, and forms an expanding foam that is sprayed onto roof tiles, concrete slabs, into wall cavities, or through holes drilled in into a cavity of a finished wall.
Buildings with spray foam insulation routinely perform 30-50% better than buildings with traditional insulation materials.
Creating an air barrier with spray foam improves energy efficiency, keeping your home warmer during the winter and helping your cooling system keep pace with the summer heat. Spray foam virtually eliminates the largest source of energy loss in the average home – the 30 to 40% of energy typically lost through air leakage.
With traditional insulation materials, HVAC professionals typically need to install larger units which cost more to install and operate. The bottom line is that heating and cooling a home insulated with spray foam typically costs much less than an average home.
