acoustic insulation / polyethylene / for flooring / panel
without vapor barrier
Schlüter®-DITRA-SOUND is a bonded impact sound insulation for tile coverings, made of a heavy polyethylene 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 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 adhesive that must be suitable for the substrate. The adhesive is applied with a notched trowel (recommended size 3 x 3 mm or 4 x 4 mm). 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.
