Warm Tiles® Self-Adhesive Mats (SAM) are ideally suited for rectangular areas, multi-unit applications, or expansive rooms. The cable is fixed onto a mesh substrate and comes in standard sizes of pre-fabricated rectangular mats with Self-Adhesive, wide-spaced backing to help reduce installation time and labor. SAM mats are designed to gently warm flooring materials such as marble, ceramic, glass and porcelain tile, slate, granite, poured or dimensional stone, laminate, and certain engineered hardwood products.
