Schlüter-Systems has reported positive 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 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% reduction by the human ear.
This new development brings the total tally of features offered by this product to seven, 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% 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.
