Value and Performance
DiamondBack™ 12 mil crawl space liner is made to handle the harsh crawl space environment with ease. It is made using 100% virgin polyethylene film laminated together with molten polyethylene tie layer. Manufactured in an ISO 9001:2015 certified facility, you can expect a consistent quality that exceeds the demands of your crawl space.
DiamondBack™ is offered in a bright white finish for excellent light reflection helping your crawl space to not only look clean but be clean. We put a UV inhibitor on the white side to protect the barrier from the sun for 18 months. The back side is made black using carbon, which will protect the crawl space liner for much longer and is the best side to install up with open vents that allow sunlight in.
What Makes It Great?
This 12 mil crawl space liner is protected with a 1000 denier polyester, the same cord used in bias ply tires. The reinforcement protects the liner from ripping or tearing and will confine small holes from spreading.
Each roll is 13'4" wide and is made that width by welding two 6'9" DiamondBack™ panels together. We fold each 13'4" x 75' roll on a core that is 87", making the handling much easier. Each roll weights approximately 68 pounds.
