Constructing multi-story residential buildings with concrete can make it difficult to control impact sound through floor-ceiling assemblies. This problem can become even more complicated when hard surface coverings like tile are used.
A new membrane from Schluter Systems, Ditra Heat Duo, reduces sound transmission while also warming the floor and supporting the covering to ensure lasting installation. The system produces an increase in impact insulation class of 20 to a concrete floor slab. When coupled with the improved warm-up times, the membrane is a potential solution for ceramic and stone tile floor installations in multi-story residential construction.
Schluter Systems
Ditra Heat Duo is the first electric floor warming system with an integrated thermal break that allows the system to warm tiled floors up to 70% faster over concrete substrates by directing heat to the tile, not the subfloor.
All of these benefits are included in a single 5/16-inch layer of the membrane. Installers have the option of installing the heating cables, or not, depending on the specific needs of the situation. The heating cables are snapped into place on top of the uncoupling mat; no clips or fasteners needed.
Ditra Heat Duo performs four essential functions for a lasting tile floor installation: 1) uncoupling to prevent cracks in tiles and grout, 2) waterproofing to protect areas beneath the tile from moisture, 3) vapor management to provide a route for excess moisture to escape the substrate without damaging the tile, and 4) support and load distribution to keep the tile covering intact in the event of heavy foot traffic.
