Spray foam insulation is a spray-applied liquid plastic that expands many times its size. It is commonly installed as insulation and air or moisture barriers. Also known as spray polyurethane foam (SPF), spray foam is durable and maintains its physical properties over time. SPF has been used for over 60 years and is an extremely stable, long-lasting and a versatile material.
SPF is also among the ‘greenest’ insulation alternatives, as it requires minimal energy to transport and install. As a single product, depending on the project and formula, SPF can take the place of 3-4 other products like air barriers, sealants, vapor retarders, and weather barriers. Furthermore, studies have found that it does not release toxic gases or leach harmful chemicals into the air or soil.
Proper technical training and specialized equipment is used to apply the spray polyurethane foam in order to get the best results.
