One step closer to the sweet sound of silence

Schlüter-Systems is delighted to report the pleasing results of impact sound reduction tests on its latest innovative uncoupling membrane for crack-free tile and stone.

Schlüter® -DITRA- HEAT-TB has been renamed as Schlüter®-DITRA-HEAT-DUO, in recognition of the fact that the matting now offers two officially-verified features over its parent product DITRA-HEAT: thermal breaking and impact sound reduction. The newly-confirmed impact sound reduction of up to 13dB is perceived as a 50 per cent reduction by the human ear.

This new development brings the tally of features offered by this product to seven in total — which together aid the construction process, protect the fabric of the building and improve privacy for occupants. DITRA-HEAT-DUO is a universal substrate for tile and stone coverings; as well as providing thermal breaking and impact sound reduction, it serves as a bonded waterproofing, uncoupling, crack bridging and vapour pressure equalisation layer.

The matting is also designed for the secure attachment of heating cables as an integral part of the no-nonsense electrical underfloor heating system, Schlüter®-DITRA- HEAT-E. In terms of thermal break credentials, DITRA-HEAT-DUO pushes 80 per cent of its input to the surface during the heat-up phase, whereas alternative systems can lose up to half of the heat into the screed or subfloor.

DITRA-HEAT-DUO consists of a polypropylene membrane with a cut back stud structure, with a unique 2mm anchoring fleece laminated on the underside. It can be installed on floors or walls as part of a complete DITRA-HEAT-E system, for ultimate flexibility.
