Description

Features:

  • Schlüter-DITRA-SOUND is a heavy polyethylene mat with a thickness of approximately 3.5 mm. A fleece fabric is laminated on both sides of the mat.
  • Schlüter-DITRA-SOUND does not rot, is waterproof and bridges hair line cracks in problematic substrates.
  • The test institutes review such systems, regardless of their manufacturer, in accordance with the requirements of standard DIN EN ISO 140-8 (BS EN ISO 140-8).Taking measurements on the full assembly in a real installation situation, this test resulted in a sound impact insulation value (ΔLW) of 13 dB for Schlüter-DITRA-SOUND. However, the actual impact sound reduction of an assembly depends on the local circumstances (construction system) and may differ from this value. Consequently, the determined test values cannot be applied to specific construction site situations.
  • Schlüter-DITRA-SOUND is largely resistant to the effects of watery solutions, salts, acids and alkalis, many organic solvents, alcohols and oils. The suitability of the material must be verified based on the specific chemical stresses, including the anticipated concentration, temperature and length of exposure. The water vapour permeability of the material is relatively low.
  • In conjunction with Schlüter-KERDI, Schlüter-DITRA-SOUND provides a waterproof assembly for ceramic tile and natural stone applications.
  • The tiles are installed directly over Schlüter-DITRA-SOUND in accordance with the applicable regulations, using the thin-bed method. The thin-bed mortar bonds with the fleece fabric on the topside of the mat. This results in the complete bonding of the entire system.
  • The floor/ceiling structure absorbs the structure borne noise and transmits the resulting impact sound in the form of airborne noise. The heavy mat material absorbs much of the impact sound created by walking and reduces the drum roll effect.
  • The insulation panel is suited for renovation and refurbishment projects in buildings, but also for new construction projects.
  • Crack bridging Schlüter-DITRA-SOUND can be used to bridge cracks, which are not expected to widen significantly or show height displacement. This ensures that cracks in the substrate are not transferred to the tile covering.
  • If high traffic loads are expected (maximum 5 kN/ m2; e.g. in commercial applications), the tiles must be sufficiently thick and pressure stabilised for the corresponding application area. In areas with high traffic loads, it is particularly important that the tiles are fully embedded in the tile adhesive. Tiles should at least have a dimension of 50 x 50 mm.

Schlüter-DITRA-SOUND may be installed over the following substrates:

  • Concrete.
  • Cementitious screeds.
  • Calcium sulfate screeds (residual moisture content 0.5 CM% or less).
  • Heated screeds.
  • Plywood panels that are specially treated to prevent the absorption of moisture. The thickness of the panel should be selected to ensure sufficient impact resistance in conjunction with a suitable support structure.
  • Hardwood floors provided the floorboards have tongue and groove connections, are sufficiently load bearing and are securely screwed down.
  • Stair treads and risers.

Installation is preferred by Schlüter-Systems trained installers.
