12 Mil GuardianLiner® HS

12 Mil Vapor Barrier for the crawl space, GuardianLiner® High Strength

Our 12 Mil Vapor Barrier, GuardianLiner® High Strength is designed by us and made to our strict standards in Canada. We use polyethylene ribbons to reinforce this 12 mil vapor barrier, just like we do with our 20 Mil crawl space moisture barrier. 

To reinforce this 12 mil vapor barrier we cut thin ribbons of polyethylene and stretch them until they are at their strongest. With these ribbons now strengthened we weave them in a cross hatch pattern to cover 100% of the 12 mil vapor barriers surface. Once the reinforcement is ready we then laminate a PURE Premium® layer to the reinforcement to give the 12 mil vapor barrier a smooth surface and high quality professional look. Once the lamination process is done we ship the master rolls to our facility in Greenwood, SC where we inspect, send for testing, fold and package the rolls ready for shipment.
