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.
