Spray Foam FAQ
What is Spray Foam Insulation
Spray foam insulation, also known as spray polyurethane foam insulation, is a product that is applied with a sprayer that mixes two liquids. The foam expands to fill cavities and cover surfaces completely, and it can be used to insulate in walls, attics, ceilings, floors, and basements and crawlspaces.
How is spray foam different from traditional insulation?
Spray foam insulation is an air barrier and thermal barrier all in one. This means that spray foam insulation does the job of providing insulation and air sealing with one product, whereas traditional forms of insulation do not provide any barrier to the flow of air.
Is spray foam insulation safe?
Yes, spray foam is safe. Some people can be sensitive to the fumes, but they go away between 12-24 hours after application.
How long does it last?
If undisturbed and shielded from direct sunlight, spray foam should last the lifetime of the structure. It does not break down, so it lasts indefinitely.
