DESCRIPTION Mapeheat Membrane is a lightweight uncoupling, anti-fracture and waterproofing membrane for electrical underfloor heating. This patented membrane is designed to speed up the installation of tile and stone in interior rooms such as bathrooms, kitchens and living areas where the luxury of radiant floor heating is desired. Mapeheat Membrane’s thin profile works well with remodelling projects where the new floor will be installed directly over a pre-existing one. Once the heating cable is set within Mapeheat Membrane’s rounded square reliefs, a tile adhesive or levelling/ smoothing compound can be applied immediately.
WHERE TO USE • Use under ceramic, porcelain and natural stone tiles in interior residential spaces such as kitchens, bathrooms, shower floors and living areas. • Use as a substrate for self-levellers under engineered wood, luxury vinyl tiles, luxury vinyl planks, laminate flooring and mosaic tile.
