In a home in Columbia Station, we properly insulated and sealed a damp and leaky crawl space with our CrawlSeal and ExTremeBloc insulation. We also air-sealed areas where the cold, damp air could enter in between floor joists. Our CrawlSeal vapor barrier is a 20 ml thick plastic liner comparable to a pool liner, which has multiple layers so it will not tear and rip. It is an excellent barrier to the wet, moist air rising from the ground, creating the damp crawl space environment. Our ExTremeBloc insulation was installed on the walls which has R-10 rating. Our customer can now use their crawl space for storage and the upstairs of the home will not be losing heat as the level below remains warm and dry.
