The concrete construction of multi-story buildings makes controlling impact sound through floor-ceiling assemblies challenging, particularly with hard surface coverings like tiles. Sound control materials tend to be compressible and not all provide adequate support for the tile covering. DITRA-HEAT-DUO reduces sound transmission in addition to warming the floor and still supporting the covering to ensure a lasting installation.

ASTM E2179 testing shows DITRA-HEAT-DUO produces an increase in impact insulation class (IIC) of 20 to a concrete slab floor. The dual benefits of reducing impact sound transmission and providing faster warm-up times make this membrane ideal for hard surface floors in multi-story residential construction.
Schluter-DITRA-HEAT-DUO is the first electric floor warming system with an integrated thermal break and sound control to overcome these multiple challenges. The thermal break on the underside of the membrane allows the system to warm tiled floors up to 70% faster over concrete substrates by directing heat to the tile, not the subfloor. The system provides faster and simpler installation as the membrane, heating cables, thermal break and sound control material are all combined in a single layer only 5/16” thick. Also available with a Wi-Fi thermostat for fast, easy programming from home or on the road.
