    Timeless – elegant – functional

    In energy-efficient buildings with thermal activation of building structures, high demands are placed on the room acoustics. With a free cross-section of 80 percent and a sound absorption value (sav) of 0.35 (H), the acoustic slat is the link between a good climate and pleasant room acoustics. The slats are micro-perforated and equipped with a Special profile filling of sound-absorbing acoustic fleece.

    This results in a full-area absorption of the room sound. Due to the notably large free cross-section, the air from the building services installations can descend spatially through the ceiling. In contrast to the conventionally circulating air, air falling from above is perceived as particularly pleasant. This prevents the effects of drafts.

    The acoustic slats’ profiles are filled with a special acoustic fleece. The profiles are 10 mm wide. The slat height is 40 mm standard. Special heights of 50 or 70 mm are also feasible. The material thickness is 0.4 to 0.5 mm.

    Sound absorption with acoustic slats
    In conjunction with sound-absorbing walls and floors, sound absorption values (sav) of sav = 0.35 (H) according to the German standard DIN EN ISO 11654 facilitate perfect room acoustics, without influencing the climatic characteristics of the thermal activation of building structures.

    Improvement of sound absorption
    As an accessory, we offer an absorber system, which is integrated into the substructure of the slat ceiling. It is available in different variants and allows an additional improvement of the sound absorption in the room. The slat system still offers a free cross-section of 80 percent. However, this facilitates a sound absorption value of 0.3 – 0.6.

    As a matter of fact, our slat systems can also be covered with a panel with acoustic effect (e.g. from Rockfon company). Doing so, you can achieve sound absorption values of up to sav = 1.0 (H). However, this closes the system. Hence, fire protection installations must be
    implemented in a second layer.
