Schluter Systems Ditra Heat DUO Membrane, 8.4 Sq Ft (0.78 Sq M) Sheet, DHD8MA, Waterproofing Uncoupling Underlayment for Floor Warming

Product Features:

• 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
• Available by the roll or by the sheet to accommodate various room sizes
• The stud structure of DITRA-HEAT-DUO DHD8MA 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
• DHD 8MA Provides electric floor warming for use beneath tile, stone, or other resilient floor coverings (e.g. LVT)

Product Description:

Schluter®-DITRA-HEAT-DUO DHD8 MA 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 heat loss to the substrate, improve floor warming response time, and reduce sound transmission through floor-ceiling assemblies.

Controlling impact sound transmission through floor-ceiling assemblies in multistory construction can present challenges, particularly when ceramic and stone tiles are used. Sound control materials tend to be compressible and not all provide adequate support for tile covering in thin-set applications. DITRA-HEAT-DUO reduces sound transmission, while supporting the covering to ensure a lasting installation.

DITRA-HEAT-DUO DH D8 MA 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 for ceramic, porcelain, and stone tiles, significantly reducing installation time and effort compared to uncoupling membranes over other electric floor warming systems. Self-leveling compounds are approved for use only when installing alternative floor coverings over the DITRA-HEAT membranes.

Tile has been successfully installed for thousands of years by incorporating an uncoupling layer, or forgiving shear interface, within the tile assembly. 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 DHD 8 MA 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 that could otherwise cause damage to the tile covering above. Thus, DITRA-HEAT-DUO effectively manages moisture beneath the tile covering.
