The Barrier™ underground insulation is a high-performance, easy to use and cost effective material for underground and under concrete insulation requirements. The core component is an extruded EPS. Both sides are laminated with a tough heavy-duty 3mil polyethylene film. One side of the film has a 1 inch overlap running the length with a double-faced adhesive on the bottom side, allowing one roll to be butted up to the next roll, giving you a seamless closure.
It provides excellent resistance to the transfer of heat and cold. The extruded foam effectively creates an "igloo" effect. The Barrier™ has a K-Value of .019. It has the ability to stop all forms of moisture transfer. The combination of extruded foam and heavy film completely stops any and all forms of moisture transfer.
