Manufacturer
akustikplus GmbH & Co. KG
akustikplus develops and manufactures decorative acoustic solutions from wood-based materials at its site in Stephanskirchen near Rosenheim. The company belongs to the Hamberger Group and combines industrial production with real-wood veneer expertise. The range comprises four product lines: smartline (acoustic panels with an integrated wood-wool absorber), slimline (slender slotted panels mounted over a mineral-wool insulation layer), proline (micro-perforated acoustic boards, also available as a furniture board decorative on both sides) and designline (felt panels with veneered MDF slats). Non-combustible versions on a gypsum-fibre base are available on request.
Description
The slimline is a slim, slotted MDF acoustic panel for mounting on a substructure. The acoustic effect arises from the interaction of the slotted face with a mineral wool insulation layer behind it, and, depending on the build-up, with an additional open cavity. The panels join into a continuous surface via a tongue-and-groove joint. The stripes version varies the web widths irregularly. This creates a lively, striped joint pattern instead of the uniform grid.
