The Barrier Under-Slab Insulation
The Barrier™ underground insulation is a high-performance, easy to use and cost effective material for all of your underground and underconcrete insulation requirements. The core component is an extruded expanded polystyrene (EPS) material with a tough, heavy-duty 3mil polyethylene film laminated to both sides. Along the 60 foot edge of The Barrier™, there is a 1" overlap of film running the length of the material with an aggressive double-faced adhesive on the bottom side of the overlap. This allows one roll to be "butted" up to the next roll. Simply expose the back of the tape, compress, and you have a seamless closure that will not allow the transfer of heat/cold and will completely eliminate the transfer of all forms of moisture.
