12 Mil Dura-Skrim 12WB Crawl Space Vapor Barrier
$190.00 – $256.99
Raven Dura-Skrim 12WB is a 12 mil reinforced plastic sheeting often used in crawlspace encapsulation. This is a medium weight polyethylene with proven durability.
Does your DIY project call for a medium weight (8 to 16 mil) reinforced plastic sheeting with exceptional durability? It’s our Raven Dura-Skrim 12WB 12 mil, both puncture and tear resistant, is what you are looking for.
Dura-Skrim 12WB (12 mil white on one side and black on the other) is made of two sheets of high strength polyethylene film laminated together with a third layer of molten polyethylene. Inside there is a heavy duty diamond shaped network of scrim (string) for reinforcement which greatly enhances tear resistance and increases service life. The white outer layer contains UV inhibitors and thermal stabilizer and is designed to reduce heat buildup and condensation. The black outer layer contains carbon black to give it long life when in contract with soils.
Dura-Skrim 12WB is the first choice for applications requiring greater performance than common 8 to 16 mil plastic sheeting.
23.5′ x 50′ and 12′ x 100′ Rolls are ideal for crawlspace floors. Fewer seams, improved seal, better results. 12′ x 100′ and 4′ x 200′ Rolls are ideal for crawlspace walls. (4′ is suggested for walls no taller than 3′.)
