Schluter® DITRA-HEAT-DUO Sheet — 3'2-5/8" × 2'7-3/8" (8.4 SF) Fill Piece
- Features integrated sound control and thermal break
- 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
Description
Description
A single 8.4 sq ft sheet of DITRA-HEAT-DUO membrane — same heated floor, sound control, and thermal break performance as the full roll, in a pre-cut piece for finishing off small areas or topping up a roll that ran short.
- 32-5/8" x 27-3/8" sheet — heating cables snap directly into the stud channels, same as the full roll
- Includes integrated thermal break and sound control layers — reduces downward heat loss and impact noise transmission between floors
- Bond to subfloor with unmodified thin-set — same installation method as standard DITRA-HEAT-DUO rolls
Pro tip: Order a couple of sheets alongside your main roll to cover the odd corners and transitions without cutting into a second roll. They're also the right call for a small powder room or entryway heated floor.

How DITRA-HEAT Works in 4 Steps
1. Install the membrane
Bond DITRA-HEAT to your substrate with unmodified thinset. Works over concrete, plywood, or OSB subfloors.
2. Snap in the cable
Run the DITRA-HEAT-E-HK cable between the studs at 3″ spacing. No mesh, no staples, no plywood overlay.
3. Tile right over it
Apply thinset and set tile, stone, or LVT directly on the studs. The membrane stays as your waterproof, uncoupled layer.
4. Set your thermostat
Wire the included floor sensor to any DITRA-HEAT thermostat — basic, touchscreen, or WiFi smart — and you’re heating.
