The concrete construction of multi-storey 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, formerly DITRA-HEAT-TB, 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 (ΔIIC) of 20 to a concrete slab floor. The dual benefits of reducing impact sound transmission and providing faster warm-up times make this membrane an ideal solution for ceramic and stone tile floor installations in multistorey residential construction.
Schluter’s DITRA-HEAT-DUO is the first electric floor-warming system with an integrated thermal break and sound control to overcome these multiple challenges. The relatively thin thermal break on the underside of the membrane allows the system to warm tiled floors up to 70 per cent faster over concrete substrates by directing heat to the tile, and not to the subfloor. The all-in-one system means faster and simpler installation as the membrane, heating cables, thermal break, and sound-control material are all combined in a single layer that is only 5/16-in. thick.
