Product Description
The 20 Mil Woven-Coated Crawl Space Vapor Barrier is the thickest, heavy-duty option in Crawlspace Depot's woven-coated line. It uses the same woven-coated construction as the 10 mil and 14 mil liners, with woven reinforcement extending across the material and added thickness for demanding crawl space conditions.
This liner is well suited for installations with rough or uneven ground and crawl spaces likely to receive repeated access. It is a woven-coated product, distinct from the 20 mil string-reinforced vapor barrier, giving you a choice between two reinforcement constructions at this thickness.
Use this liner across the crawl space floor, around piers, and on foundation walls. The white-on-white finish gives the crawl space a clean, bright appearance. Each 12' x 100' roll covers 1,200 square feet.
For best results, prepare the crawl space floor, overlap seams, and use the right accessories during installation:
- Use Crawl Space Vapor Barrier Tape to seal overlapped seams.
- Use Vapor Barrier Staples to help hold the material in place around edges, corners, piers, and wall transitions.
- Use Christmas Tree Fasteners to secure the liner during wall installation.
