Crawlspaces can be tricky to insulate. Traditional fiberglass insulation doesn't stop water, and actually becomes less effective when wet. Our SilverGlo insulation, installed on the back wall of this crawlspace, combines highly effective graphite-impregnated insulation with a built-in radiant heat barrier surface. This gives your crawl space walls an unbroken plane of R-11 insulation, while sealing your walls from outside moisture and humidity infiltration.
