Manufacturer
SUAM Schall- & Akustikmanufaktur GmbH
SUAM Akustikmanufaktur develops and manufactures custom room-acoustic elements made from thermally bonded polyester wadding in Bad Wünnenberg (North Rhine-Westphalia). The range covers ceiling rafts (rectangular, round, free-form), baffles, wall and ceiling absorbers, acoustic art panels, the dekaBel metal cassette absorber, and the modular free-standing screen. The PES core material is binder-free, fully recyclable and meets fire class B1 per DIN 4102. Certified to OEKO-TEX Standard 100 (test no. 94.0.0541).
Description
The SUAM Universal Absorber forms the base of the SUAM acoustic range and consists of thermally bonded polyester fiber boards. They come in three material thicknesses and can be enclosed in a wooden frame. The system can be used on walls and ceilings, hung freely or mounted directly, or as a block absorber in which several boards are combined into a larger unit. Every version can be produced in a large color range, including custom shades similar to RAL tones.
