Spray Foam Insulation
Closed-cell spray foam bonds to the surface, fills gaps and adds both an air seal and an insulation layer. It is a strong choice for rim joists and foundation walls in the right applications. Trained installers wear protective gear and the area is ventilated and cured as the maker directs.
