Keep moisture out and protect your crawl space for good with StegoCrawl® Wrap 6-Mil Reinforced Vapor Retarder, a heavy-duty, scrim-reinforced vapor barrier engineered for demanding jobsite conditions. Built with a multi-layered construction — high-strength scrim sandwiched between two layers of virgin polyethylene film — this vapor retarder delivers superior puncture and tear resistance while meeting Class I vapor permeance standards.

Whether you're installing a new crawl space vapor barrier, retrofitting an existing home, or building a soil-gas retarder for a radon mitigation system, StegoCrawl Wrap 6-Mil is a versatile, code-aligned solution you can trust. Added UV inhibitors and thermal stabilizers also make it suitable for temporary outdoor enclosure and containment applications.
