Stego Wrap 15-mil is the first virtually zero-permeance, under-slab vapor barrier extruded to exceed ASTM E 1745 Class A Standards for under-slab vapor retarders. Stego WRAP 15-mil withstood rigorous testing after wetting/drying; exposure to both elevated temperatures and very low temperatures; bending; and microorganism and soil-substance exposure. Circle

In My Own Words"We are just starting to use this as an under-slab vapor barrier in our foundations. We install the 15-mil product while also sealing all pipe penetrations through the vapor barrier. It costs more than our old visqueen product, but is worth every cent, and is S-800 compliant."
