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 "G" range from alpha AKUSTIK consists of slotted MDF panels with a SoundTex acoustic fleece on the back, made in several slot patterns. Their narrow, evenly spaced slots give walls and ceilings an understated look. The panels come raw, veneered or coated and are installed on mineral wool, with an air cavity, or in a slim build-up with the SoundTex fleece alone and no mineral wool.
