alpha AKUSTIK
alpha AKUSTIK is the acoustics brand of Staudigel GmbH from Veitshöchheim — a family business with over 70 years of experience in wood processing. On around 80,729 sq ft of production area the company manufactures sound-absorbing perforated, slotted and micro-perforated panels (NANOLITE) on an MDF base for wall and ceiling. The panels are built up with a backing acoustic fleece (SoundTex) and mineral insulation into acoustically effective claddings. The range spans from discreetly perforated visible surfaces to highly absorbent slot-and-hole patterns and is broadly documented by accredited reverberation-chamber measurements (Fraunhofer IBP, BAE Fiedler, ita).
Description
The alpha AKUSTIK "BV" slot-and-hole panel is an MDF carrier board perforated with a combination of slots and holes, backed with an acoustic fleece and mineral wool (Isover SSP2 or Rockwool Sonorock). It serves as a wall and ceiling lining and comes in several slot-and-hole patterns, plus the "Vari" range with variable slotting. Surfaces can be raw, veneered or coated, and the panels mount directly on the mineral wool or with an air cavity behind them.
