Crawl Space Insulation - Debris & Vapor Barrier
Many crawl spaces have debris left from the home's construction, maintenance on equipment in the crawl space, or storage. The 6-mil vapor barrier installed at construction is not durable enough to withstand this kind of traffic causing it to be torn or displaced. In addition, the liner is not sealed to the walls, itself, or piers. This means it is not protecting the crawl space from the earth's moisture.
