Lightweight Uncoupling, Crack-Isolation and Waterproofing Membrane for Electrical Floor Heating Mapeheat Membrane is a lightweight uncoupling, crack-isolation and waterproofing membrane that also provides vapor management and load support. This patented membrane is designed to speed the installation of tile and stone in interior rooms such as bathrooms, kitchens and three-season rooms where the luxury of radiant floor heating is desired. Mapeheat Membrane’s thin profile works well with remodeling projects where the new floor will be installed directly over a preexisting one. Once the heating cable is set within Mapeheat Membrane’s rounded square reliefs, a tile mortar can be applied immediately. Recommended for use with polymer-modified mortars Membrane thickness is less than 1/4″ (6 mm) Replaces plywood or cement board as tile underlayment Works with all these floor types: ceramic tile, porcelain tile, granite, marble, natural stone, laminate/engineered wood floors, luxury vinyl tile (LVT) and luxury vinyl plank (LVP) Heating cable lays flat and secure UL-certified for wet environments, such as shower floors Suitable for areas with up to 25 lbs. (11.3 kg) MVER and 100% relative humidity Does not support mold growth
