Schluter Ditra Heat Duo 3' 3" x 33' Membrane Roll

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 rolls are great for covering large areas 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

What is the spacing requirements for DITRA-heat?

A cable spacing of 3 studs between runs is standard. However, cable may also be spaced at continuously alternating 3 stud – 2 stud intervals in isolated areas or over the entire floor.

Does DITRA prevent tile from cracking?

The rib structure allows for in-plane movement that effectively neutralizes the differential movement stresses between the substrate and the tile, thus eliminating the major cause of cracking and delaminating of the tiled surface.

This is the only product I have used for under tile heating over concrete, so I can't compare with others. With that said, Schluter products have always worked well for me. Never disappointed. Can't go wrong with Ditra_Heat Duo.

Another decent solution product from Schluter, good quality and easy to work with. Just to make sure to align pegs when you install different pieces side by side.
