12 Mil DiamondBack™ SL

12 Mil Crawl Space Liner

12 Mil DiamondBack SL

This American Made 12 mil crawl space liner is a string reinforced vapor barrier that can be compared to most other brands on the open market for the same stated thickness, 12 Mil. Actual 12 mil is equal to .012", not 12mm. This product is a nominal 12 mil, meaning does not measure 12 mil at the plastic, but it is close.

This crawl space liner does not contain any additives and is reinforced with a 1000 denier polyester cord to stabilize the layers and prevent tearing.The appearance of this crawl space liner is bright white on the face and black on the back. Although it shares the color scheme of different brands on the market it is not the same. You will not find small pin holes in the this vapor barrier like you will in other white/black combination liners. This product is available in the roll size of 12' x 85'. However, prior to shipping we fold the vapor barrier in half and roll it on an 82" core.
