polystyrene foam insulation board with patented dovetail
grooves cut into one face of the board and shiplap
edges on the long edges. When installed on the exterior
of basement walls, it provides insulation, protects
the waterproofing membrane and assists water drainage
away from the foundation. Qualifies as Class A Type
