Spray foam insulation typically lasts the lifetime of the building when installed correctly, since it does not settle, sag, or degrade over time.
Yes, our team can apply spray foam in attics, crawlspaces, and rim joist areas without disturbing your existing finished walls.
Open-cell foam is lighter and more flexible, ideal for sound control and air sealing, while closed-cell foam is denser and offers a higher R-value per inch plus a built-in moisture barrier.
Closed-cell spray foam acts as both an insulator and a vapor barrier, which helps prevent moisture from entering your home through walls, crawlspaces, and foundations.
Once fully cured, spray foam is inert and does not off-gas or produce particles, and it actually reduces airborne allergens by sealing out dust and pollen through air leaks.
