Crawlspace 1800 is an 18 mil (true thickness) reinforced 6 layer extrusion lamination polyethylene designed specifically for use in the crawlspace and basement industries. This film has a black back layer and two layers of bright white film, giving it a very bright white front side for a pleasing appearance. Designed as a cost effective wall covering/vapor retarder, Crawlspace 1800 is well suited to the needs of the crawlspace and basement industry.
Crawlspace contains at least 50 strands of high strength cord per square foot, in a square pattern. Because all layers are extrusion laminated together using molten polyethylene, this is an incredibly strong film, yet, lightweight and easy to use.
Though designed for the crawlspace and basement industries, Crawlspace 1800 can be used in many applications. We can fabricate this product into 3-D shapes, add many accessories, like bung ports, drains, grommets, hems, and loops.
Crawlspace 1800TM is currently stocked in 12' x 100' and 20' x 50' rolls. Available in many custom sizes.
