Its multi-layered construction — high-strength scrim reinforcement bonded between two layers of virgin polyethylene film — delivers the strength and moisture control contractors need without the bulk of heavier-gauge films. Suited for new construction or retrofit crawl space encapsulation, soil-gas and radon mitigation systems, and temporary enclosure or containment applications, StegoCrawl Wrap 12-Mil offers a Class I vapor rating that exceeds ASTM E1745 requirements. It's also independently tested for UV resistance, making it a strong choice for extended outdoor exposure during construction. Why Choose StegoCrawl Wrap 12-Mil Reinforced?
