Timeless – elegant – functional

In energy-efficient buildings with concrete core activation (BKT), high demands are made on room acoustics. With a free cross-section of 80% and an acoustic absorption value (aw) 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 sound-absorbing acoustic fleece to fill the profile. In this way, we achieve full absorption of the ambiance. Due to the particularly large free cross-section, the air of the technical building services units can fall down two-dimensional through the ceiling. Compared to the conventionally circulating air, air falling from above is perceived as particularly pleasant because there are no drafts.

Making acoustic absorption variable

To increase the absorption of the reverberation, the acoustic system can be supplemented with additional options. Always consider whether the ceiling system may close the free space to the bare ceiling or whether the system’s large free cross-section needs to be used. This is the case, for example, with concrete core activation.

Variant A:
All of the slat systems we offer can be covered with a highly effective acoustic panel or an acoustically effective fleece. Both the acoustic panels and the acoustic fleece are placed directly on the slats. The functionality of the acoustic panel and the acoustic fleece is not significantly impaired by the system’s high free cross-section. Therefore, an aw value of up to 1.0 (H) can be achieved. However, this closes the system. This aspect must be considered with regard to fire protection regulations, etc.

Variant B:
Our low-frequency absorber system is additionally installed (by the customer) vertically on a CD profile supporting construction above the slat system. This allows the aw value to be increased by 0.6 (H) maximum. The ceiling system is not closed and the high free cross-section can still be taken advantage of.

This system can also be combined with all of our slat systems. The absorption values differ in combination with the standard system and the acoustic slat system. The low-frequency absorber system can be planned in the slat and/or carrier rail run. The entire system is available in fire protection class A.
