• Features integrated sound control and thermal break Reduces impact sound transmission through floor-ceiling assemblies Reduces heat loss to the substrate for up to 70% faster heat-up times over concrete The stud structure of DITRA-HEAT-DUO is specifically designed to allow for the easy installation of DITRA-HEAT-E-HK heating cables Nominal 5/16” (8mm) thickness minimizes tile assembly thickness and reduces transitions to lower surface coverings ›See more product details.

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. Optionally, the system can be customized with floor heating cables to create a warm, luxurious tile floor. Schluter-DITRA-HEAT-DUO integrates customizable, comfortable electric floor warming with the functions of DITRA: uncoupling, waterproofing, vapor management and support to ensure a long lasting installation. DITRA-HEAT-DUO features an integrated thermal break to reduce impact sound transmission through floor-ceiling assemblies, reduce heat loss to the substrate, and improve floor warming response time. Controlling impact sound transmission through floor-ceiling assemblies in multistory construction can present challenges, particularly when ceramic and stone tiles are used. DITRA-HEAT-DUO reduces sound transmission, while supporting the covering to ensure a lasting installation. DITRA-HEAT-DUO combines the flexibility of loose heating cables with the ease of installation of mat systems. Cables can be placed wherever heat is desired, without creating height differences in the floor. Self-leveling compounds are not required to encapsulate the cables, significantly reducing installation time and effort. DITRA-HEAT-DUO provides uncoupling through its geometric configuration, which 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. DITRA-HEAT-DUO provides reliable waterproofing. Its polypropylene composition protects the substrate from moisture penetration, which is particularly important in today’s building environment where most substrates are moisture-sensitive. The free space on the underside of DITRA-HEAT-DUO provides a route for excess moisture and vapor to escape from the substrate.
