Heavy-duty crawl space vapor barrier with reinforced 10-mil thickness — twice the thickness of standard 6-mil barriers. The nylon-reinforced core prevents punctures from rocks, debris, and foot traffic during installation and inspection. Covers 1,200 sq ft — typical for a 30x40-foot crawl space. Anti-microbial additive inhibits mold growth on the barrier surface — critical in flood-prone crawl spaces where residual moisture can persist for weeks.
