It is made with recycled, extruded polystyrene and heavy-duty black polyethylene film (less than an inch thick), laminated on both sides and with patented seamless self-taping edges. It can be used under slabs, basements, foundations, crawl spaces, pools, hot tubs, and mobile or modular homes. It also deters carpenter ants, termites and other insects.
