Manufacturer
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 7,500 m² 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 "G" slotted-panel range: slotted MDF panels with a backing SoundTex acoustic fleece in several slot patterns (8-2 G to 32-4 G). The narrow, even slotting gives a restrained visible surface for wall and ceiling. Tunable via slot pattern and backing, from class D to B. Also available without mineral wool, with the SoundTex fleece alone (slim 59 mm build-up).
