3/8 in W x 4 ft H x 100 ft L Slab Shield

Slab Shield insulation was designed specifically for use under concrete slabs both with and without hydronic heating products. It provides a vapor barrier and significant thermal performance. The product has a layer of 99% pure aluminum film sandwiched between two layers of closed cell polyethylene foam. Slab Shield is not affected by the chemical reaction of curing concrete and does not crack or crumble when faced with normal job site abuses.
