Here in Spring Lake, NJ we just finished insulating a crawl space. We spray foamed the rim joists of the crawl space and insulated the foundational walls with our SilverGlo foam insulation panels. Next we installed our TerraBlock foam insulation mat by staking it securely to the ground. Then our CleanSpace encapsulation liner is installed across the floor and sealed with mechanical fasteners to the walls and spiked to the floor. Finally we use our orange ZypFoam sealant to seal all the seams or gaps of the SilverGlo foam insulation and on the seam of the CleanSpace liner where the liner meets the walls.
