Spray Polyurethane Foam (SPF) Insulation
Spray Polyurethane Foam, or SPF, is a high-performance insulation material commonly used in homes and buildings of all types. SPF is particularly known for its ability to help improve the health, comfort, and energy efficiency of a home. Use of the material can dramatically reduce the energy costs associated with heating and cooling, while helping to keep the home interior comfortable year-round, even as the seasons change.
SPF has been used as insulation in homes and buildings for decades. As a new homeowner or prospective buyer, you may have questions about the material and how well it works. This guide will help you better understand why SPF is a leading choice of insulation by homeowners.
Benefits of Spray Foam Insulation
SPF acts as a single-material solution for thermal, air, vapor and water vapor transmission through the home’s building envelope, or enclosure. Think of the enclosure of the home as what a set of clothing is for the human body on a windy, damp winter day. A sweater (fibrous insulation) provides insulation (R-value) to retain body heat – but it does not stop wind (air movement) or control moisture. You would be very uncomfortable with just a sweater; you would be more comfortable adding a thin waterproof windbreaker (air barrier and vapor retarder). SPF insulation is the only insulation inside stud walls that can provide R-value, air barrier and vapor barrier in a single product.
