20 Mil Vapor Barrier — High Strength™ by SilverBack®
High Strength™ is a 20 Mil Vapor Barrier and the gold standard in crawl space moisture protection. Engineered for performance, this barrier is constructed from 100% virgin polyethylene resin and reinforced with high-strength polyethylene ribbons woven in a cross-hatch pattern.
