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 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.

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 crawl space floors.  Fewer seams, improved seal, better results.  12′ x 100′ and 4′ x 200′ Rolls are ideal for crawl space walls.  (4′ is suggested for walls no taller than 3′.)

    I used the 12 mil and it was easy to work with. Strong, durable, and easy to layout. I only wish I had more left over. I have used every scrap for other projects around the yard.
