attic insulation isn’t your standard insulation material. It’s made from two separate chemicals—polyol resin and isocyanate—that combine to form a foam that expands when sprayed. This expansion helps it fit into hard-to-reach spaces and creates an airtight seal after it hardens.
This helps to prevent heat transfer in and out of your home, which can reduce your energy consumption. It also helps to keep moisture out, which can prevent costly issues like water damage repair and mold remediation.
Key Considerations for Selecting Spray Foam Insulation
The best thing about spray foam is that it’s environmentally friendly. It contains fewer chemicals than fiberglass insulation, and the blowing agents used to help it expand are now more eco-friendly. It’s even possible to find foam insulation with low GWP (Global Warming Potential).
Closed cell spray foam is especially effective at preventing moisture, and can be used during the rough-in phase of construction to fill any cracks or voids in walls and floors. This helps to prevent places like attics and crawl spaces from becoming damp and humid, which can increase the likelihood of structural issues and costly moisture-related repairs.
Regardless of the type of spray foam you choose, it’s always recommended to have professional technicians install it. Not only does this ensure a quality job, but it also helps to protect your safety and health. Spray foam insulation can off-gas large amounts of volatile organic compounds during the spraying and curing process, so it’s important that homeowners stay out of their homes until the foam has had a chance to fully cure.
