StegoCrawl Wrap 15-Mil Vapor Barrier for Crawl Space Applications

StegoCrawl Wrap 15-Mil Vapor Barrier is a premium, multi-layer liner engineered to provide superior moisture protection in crawl space environments. Designed to impede water vapor movement, it helps prevent mold and mildew growth while improving indoor air quality and protecting building materials from moisture-related damage. With extremely low permeance and enhanced durability, it significantly outperforms standard poly sheeting.

Available in multiple roll sizes to suit both horizontal and vertical applications, this vapor barrier is ideal for ground cover, foundation walls, and crawl space piers. Its high-performance construction eliminates the need for reinforcement while delivering exceptional strength and long-term reliability. Manufactured in the USA with zero VOC content and Class A fire rating, it meets ASTM E1745 and Class I Vapor Retarder standards, making it a trusted solution for crawl space encapsulation projects.
