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 round-perforated acoustic panel from alpha AKUSTIK (Staudigel GmbH) is made for wall and ceiling linings and consists of an MDF carrier board with a SoundTex acoustic fleece on its back. Hole patterns, defined by grid spacing and hole diameter, range from discreet perforations to more open patterns, plus a scattered pattern with mixed hole diameters. Panels come raw, veneered or melamine-coated and mount directly on mineral wool or with an air cavity behind them.
