The air-sealing power of spray foam insulation makes it a great choice for tight, difficult to insulate areas of a home, such as attic walls and corners, basement rim joists, overhangs, knee walls, and bonus rooms. It also provides a tight seal around doors and windows, and improves indoor air quality by reducing allergens like pollen and dust.
Top Benefits of Choosing Spray Foam Insulation from Quality Insulation
Professional installation is key to a successful project. A spray foam contractor has the training and experience to ensure proper application, achieving an optimal R-value throughout your home. This is important for your energy efficiency, comfort, and health.
The blowing agent used in spray foam insulation is a mixture of two chemicals (isocyanate and polyol resin, typically). They are kept in separate hoppers or tanks until they are mixed together at the tip of a spray gun. They combine to form a dense, hard foam that fills and adheres to gaps, cracks, and crevices. The foam dries quickly and creates an effective air and vapor barrier.
Most spray foam insulation products still use hydrofluorocarbons (HFCs) as a blowing agent, but many companies are beginning to transition to low-GWP foams. The leading HFC-free spray foam brands, such as Insulthane and Gaco, use polyols that are sourced from natural renewable resources or post-consumer recycled plastics. The lower GWP of these newer products is good news for the environment.
