Stego Wrap 10 Mil Class A Vapor Retarder | 14' x 210'

Designed for foundation contractors installing moisture barriers beneath residential and commercial slabs, this 10 mil Class A vapor retarder provides code-compliant protection against ground moisture migration. The 14-foot width covers more area per roll with fewer seams, reducing installation time on large pours. At 210 feet long, each roll delivers 2,940 square feet of coverage. The Class A rating meets ASTM E1745 requirements for low permeance, blocking water vapor transmission through the concrete assembly. Puncture-resistant construction holds up during rebar placement and concrete placement operations. Works under both interior and exterior slabs where moisture control is required by building codes. Built for concrete contractors, foundation specialists, and commercial builders working on projects that demand engineered vapor barrier systems.
