Acoustic Expandable Slabs AcouCell – Expa

AcouCell Expa expanding sound absorbing slab Honeycomb laminated foam expandable slabs, that effectively traps sound and reduces the reverberation time.


AcouCell Expa is a product of special design It consists of honeycomb foam sheets which are then micro-perforated, resulting in an increase in the sound absorption coefficient. With a special cutting method applied, the acoustic sheets can become expandable if an axial force is applied. At a thickness of 50mm, Whisper achieves NRC=1 (Class A Sound absorption class A).

This special material does not consist of fibers and therefore cannot crumble or emit irritating dust. It can be easily cleaned with standard cleaners. This makes AcouCell Expa suitable for dinning areas, such as bars, restaurants, entertainment centers, etc.
