DITRA-HEAT Membrane Sheet 39"x31" = 8.4 SF | DH5MA


Warm & protect your floor at the same time!

DITRA-HEAT by Schluter-Systems integrates electric floor warming with the functions associated with DITRA: uncoupling, waterproofing, vapor management, and support to ensure a long-lasting installation under tile or stone floors.

  DITRA-HEAT combines the flexibility of loose heating cables with the ease of installation of mat systems.
  Cables can be snapped into place wherever heat is desired, which significantly reduces installation time and effort.
  Tile directly over DUO or pour self-leveler over the top to install alternate floor coverings like: 

  • Engineered Wood, floating or glued-down
  • Laminate 
  • Luxury Vinyl Tile & Plank (LVT/LVP)
  • Vinyl
  • WPC or Wood Plastic Composite core flooring
  • SPC or Stone Plastic Composite core flooring

Waterproof your installation with KERDI-BAND (sold separately); cover all joints, seams, and corners of the membrane to completely waterproof the installation before applying thin-set and tile

A great solution
Review by
These panels worked perfect as an underlayment for our new tile floor with a warm floor heating system. They are a bit hard to cut, but this is a minor issue. Check out the youtube videos of professional installations for good tips.
works as advertised
Review by
These sheets adhered well to the floor and held the heating cable in place as there were designed to. They made installing the cable easy.
I was a little confused as to what I needed to order, so I called Warm Your Floor and spoke with Omar. He had me email him a diagram of what I was doing, and he customized the heating cable, floor membrane sheets, and thermostat to my job, so I didn't order too much or too little. The installer was really impressed when the heating cable stopped exactly where it was supposed to. I am a fan...Kudos.
Good Product
Review by
I used this with (2 - WarmWire 140 Sq Ft 240V Radiant Floor Heating Cable 3.0)

Product is a bit difficult to work with if you do not keep these things in mind :
1.) The ends want to curl up when you put it down over your thinset.
2.) You cannot change the orientation of the layout once you start UNLESS you trim the excess on the long edge.

1.) Before using, unroll entire package and re-roll it in opposite direction and leave sit for a few days before using. This way the ends do not curl up when placing over the thinset. In a small area I would recommend the squares over the roll.

2.) Using the WarmWire 3.0 and the Approximate 3" spacing pg.14 on WarmWire manual, I had almost exactly 260 square feet of coverage using 280 ft. of the 3.0 cable.
Excellent Substrate
Review by
I am an electrical contractor and just completed two floors with the Ditra heat product. I will now use this everytime. Very easy to insrall the Ditra with a utility knife and thinset. Installing the heat cable is very easy because it snaps into place which puts it below the top of the mat. So you get to skip the steps of attaching the cable to the floor and do not have to embed the cable before installing tile. The cable is well protected by the Ditra heat channels and you get the added benefit of the uncoupling membrane to prevent the possibility of cracked tiles. It is not inexpensive but it is worth every penny due to the labor savings and peace of mind that you will have a successful installation with long lasting results.
