Advantages of DITRA-HEAT

Warm floors
With DITRA-HEAT, your floors can combine the beauty of tile with the comfort of an electric floor warming system to bring a touch of luxury into any room of the home.
Crack resistance
DITRA-HEAT is the only electric floor warming system that directly incorporates uncoupling technology within the system. With the proven performance of DITRA included in DITRA-HEAT, you can feel secure that your tiled floor won't crack.
Customizable heating zones
With DITRA-HEAT, the installer has the advantage of placing loose heating cables in the matting wherever heat is desired to achieve customized heating zones, or placed throughout the room to heat the entire floor.
Quick and simple installation
The DITRA-HEAT membrane is designed to secure the heating cable without clips or fasteners and the installer does not need to encapsulate the cable in a leveling compound. Tile can be installed immediately after the cable, so installation is quick and simple.
Minimum height
DITRA-HEAT minimizes assembly thickness for easy transitions to lower surface coverings, and is ideal for any room in the home.
