Schluter Ditra Sound Reduction and Insulation Acoustic Matting (See Options)

An absolute must, not just in family homes – effective sound insulation. Schlüter-DITRA-SOUND earns full points for this function. The product also stands out for its low assembly height and load transfer to the substrate. Another advantage: the heavy duty PE mat is easy to cut precisely to size with a utility knife. Simply install the mat over thin-bed adhesive and cover the abutting joints with the self-adhesive joint covering tape Schlüter-DITRA-SOUND-KB. The tiles can then conveniently be installed right away. DITRA-S355LV is available in bundles, without packaging, for large scale projects.
Schlüter-DITRA-SOUND is a bonded sound insulation assembly for tile coverings comprising a heavy duty polyethylene mat with an anchoring fleece laminated on both sides. The system was tested by an independent testing institute according to DIN EN ISO 140-8.
An impact sound improvement value (ΔLW) of 13 dB was measured in fully installed Schlüter-DITRA-SOUND assemblies.The actual improvement offered by the respective assembly depends on the local conditions (structural design) and can deviate from this value. The measured test values therefore may not apply equally to every building situation.The substrate must be level and load-bearing. Schlüter-DITRA-SOUND is installed in cementitious tile adhesive that is suitable for the substrate, using a notched trowel (recommended size: 3 x 3 mm or 4 x 4 mm). The anchoring fleece on the underside (imprinted side) of Schlüter-DITRA-SOUND is fully embedded and the fabric bonds with the adhesive. The adhesive curing time must be observed. The tile covering is installed directly over Schlüter-DITRA-SOUND in accordance with the applicable regulations, using the thin-bed method. The thin-bed tile adhesive bonds with the fleece layer on the top side of the mat. This creates a fully bonded system.
Impact Sound:
The transmission of noises caused by footsteps or dropped objects to adjoining or underlying rooms is referred to as impact sound transmission. The floor/ceiling structure absorbs the structure borne noise and transmits the resulting impact sound in the form of airborne noise.
The human ear perceives impact sound that is muffled by 10 dB as airborne noise which is reduced by 50%.
Impact sound (e.g. the noise generated by hard shoes) is also reflected back into the room. This effect is multiplied in the case of light constructions and hard surfaces, leading to the so called drum roll effect. It can be completely eliminated by the high density of the heavy mat.
Impact sound insulation
The heavy mat material absorbs much of the impact sound created by walking, for example, and reduces the drum roll effect.
It can be used to bridge cracks, which are not expected to widen significantly or show height displacement.
Ideal for high traffic commercial areas as the mat does not compress.
