Schluter DITRA-HEAT DUO 3' 3" x 2' 7" (8.6 sq. ft.) Membrane Sheet

Schluter DITRA-HEAT-DUO is an uncoupling and waterproofing membrane with an integrated bonding fleece that provides sound control, as well as a thermal break. DITRA-HEAT-DUO sheets are useful when working in a room with a difficult layout when installing floor heating cables to create a warm, luxurious tile floor.


  • Provides electric floor warming for use beneath tile, stone, or other resilient floor coverings (e.g. LVT)
  • Reduces impact sound transmission through floor-ceiling assemblies, making it ideal for multi-story construction
  • Reduces heat loss to the substrate for up to 70% faster heat-up times over concrete during temperature increase demands
  • Nominal 5/16” (8mm) thickness minimizes tile assembly thickness and reduces transitions to lower surface coverings
  • Self-leveling compounds are not required to encapsulate the cables into the membranes
  • Stud structure of DITRA-HEAT-DUO is specifically designed to allow for the easy installation of DITRA-HEAT-E-HK heating cables
  • Quick and easy to install and few tools are required
  • Patent pending

Common Questions

Do you need to wait for DITRA to dry before tiling?

Once the DITRA-HEAT membrane has been installed and the heating cables have been embedded within the membrane and tested, the tile can be installed right away. No need to wait for the thin-set mortar to cure.

Does DITRA-HEAT warm the room?

While DITRA-HEAT does offer some radiant heat that contributes to the overall comfort of the space, it is not designed to be a primary heating source for the entire room. Its main function is to provide a floor warming solution, creating a pleasant and inviting floor surface, especially during colder months.
