Mapei Mapeheat Lightweight Uncoupling, Crack Isolation and Waterproofing Membrane - 49' 3" x 3' 3" Roll

Mapeheat Membrane is a lightweight uncoupling, crack-isolation, and waterproofing membrane that also provides vapor management and load-bearing properties. This patented membrane is designed to expedite the installation of tile or stone in interior spaces such as bathrooms, kitchens, and three-season rooms where the luxury of radiant floor heating is desired. Mapeheat Membrane's thin profile is suitable for renovation projects where a new floor is installed directly over an existing floor. When the heating cable is laid between Mapeheat Membrane's raised, rounded squares, a tile mortar can be applied immediately.
