The owner of a new luxury penthouse apartment built by Radleigh Homes, of Derby, in the sought-after Derbyshire village of Duffield, displayed sound taste, by choosing the optional extra of ceramic tiling in the lounge and hallway, to complement the kitchen and bathroom tiling.
And tiling contractors Maurice Parker also showed sound taste by installing the acoustic membrane Schlüter-DITRA-SOUND to cut the impact sound perception by more than half.
The penthouse is part of the exclusive Cumberhills development from leading Derbyshire developer Radleigh Homes, which comprises 15 two-bedroomed apartments and five houses. The apartments all feature tiled kitchens and bathrooms, with an option of the additional luxury of tiles in other areas, which was specified in the penthouse.
To comply with Building Regulations for the penthouse apartment, Maurice Parker's Contracts Manager Adrian Watson, installed an acoustic flooring product directly onto the apartment's solid flooring to reduce the impact sound on the 45m² tiling. But he knew that out of the wide variety of acoustic flooring available, certain types are totally unsuitable for tiling onto. "To put tiles over a surface that is very compressible can be asking for trouble," he said. "Usually the grout lines would crack first, then the tiles would crack at the joints, and finally debond."
To overcome this, he specified Schlüter-DITRA-SOUND, which has been specially designed not only to reduce the impact sound of floor constructions (test values according to DIN EN ISO 140-8) but also to ensure that the tiled surface is highly durable. Schlüter-DITRA-SOUND is a bonded impact sound insulation, specially for tile coverings, made of a heavy polyethylene mat, which has an anchoring fleece laminated on both sides to bond with the tile adhesive - in the case of the Cumberhills development, this was PCI Tilefast 6 Rapidflex.
The tiled kitchen and bathroom floors in the five houses were fixed onto a timber substrate, so the orange Schlüter-DITRA membrane was specified to uncouple the tiles. Tiles move independently from the substrate because of different thermal expansion and contraction, but Schlüter-DITRA neutralises this differential movement, preventing stresses being transferred to the tiles. It is a polyethylene membrane with a grid structure of square cavities cut back in a dovetail configuration, and an anchoring fleece laminated to its underside. The cavities allow any stresses that occur between the substrate and the tiles to be neutralised evenly in all directions.
To finish and protect the edge of tiled splashbacks in the bathrooms, the symmetrically rounded Schlüter-RONDEC-PRO was used, with matching corner pieces. To complete the tiling installations at Cumberhills, the H & R Johnson 338 x 338 glazed floor tiles were grouted with grey PCI Groutfast 20 Rapidflex.
