Buy & Schluter DITRA-SOUND Anti-Crack & Sound Insulation Matting Sheet 0.41m² Online

Schlüter®-DITRA-SOUND is a bonded impact sound insulation for tile coverings, made of a heavy polyethene mat, which has an anchoring fleece laminated on both sides to bond with the tile adhesive. This system was tested by an independent testing institute in accordance with the standard DIN EN ISO 140-8 (BS EN ISO 140-8).

As part of a complete assembly, an impact sound insulation improvement (ΔLW) of 13 dB was determined for Schlüter®-DITRA-SOUND.

However, the actual impact of 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. The substrate must be level and ready to bear weight. Schlüter®-DITRA-SOUND is installed in an adhesive that must be suitable for the substrate. The adhesive is applied with a notched trowel (recommended size 3 x 3mm or 4 x 4mm). The underside of Schlüter®-DITRA-SOUND (i.e. the printed side) is fully embedded in the adhesive, ensuring the mechanical anchoring of the fabric in the adhesive. The curing time of the adhesive must be taken into consideration.

Tiles are installed directly over Schlüter®-DITRA-SOUND in accordance with the applicable regulations, using the thin-bed method. The adhesive bonds with the fleece fabric on the topside of the mat. This results in the complete bonding of the entire system.

Please Note: A 3 x 3mm or 4 x 4mm trowel must be used to install DITRA-SOUND to the substrate.
