TerraShield® Technical Data SheetTerraShield is a significant step forward for vapor intrusion barriers. Employing an innovative metallized film technology, TerraShield provides superior chemical resistance over any existing vapor barrier currently on the market. It is the ideal vapor mitigation solution for residential, industrial, and commercial developments with volatile contaminant impacts that represent significant health hazards and economic liabilities.

TerraShield incorporates major technological advancements over existing barrier technology to offer a reliable long-term solution for vapor intrusion concerns. Tested against leading vapor barrier systems, TerraShield provides up to 100x the performance and uses a nitrile-advanced asphalt latex core instead of a styrene butadiene-based core.
