BASWA acoustic AG

BASWA acoustic AG, Marmorweg 10, 6283 Baldegg (Canton of Lucerne), Switzerland, has been making seamless acoustic systems for more than 30 years, with production in Baldegg. Its subsidiary BASWA acoustic Deutschland GmbH is based in Düsseldorf; in North America the systems are supplied through BASWA acoustic North America in Cleveland, Ohio, and worldwide through partners. Acoustic panels are bonded or fixed and coated with microporous plasters made with marble sand, so the finished ceiling or wall looks like plaster. The system families are BASWA Phon (glass wool panel), BASWA Natural (hemp fiber panel), BASWA Basic (panel of expanded recycled glass granulate), BASWA Cool (with integrated capillary tubes for heating and cooling), BASWA Core (for concrete core activation) and BASWA DTG (fixed directly to a metal grid), with the finishes Base, Fine and Top as well as Casual and One. The systems are installed only by applicators trained and certified by BASWA, and a cleaning, repair and renovation concept covers the surfaces.

Description

BASWA Phon Base is a seamless single-coat acoustic plaster system. BASWA Phon glass wool acoustic panels are bonded to the ceiling or wall, sanded flat and coated with BASWA Base, a microporous acoustic plaster made with marble sand. The finished surface looks like a smooth plastered ceiling or wall. BASWA Base has the coarsest structure of the BASWA finish coats. The surface can be left smooth or individually textured, and the single coat keeps installation short. For flat or inclined ceilings and walls with little or no grazing light, in new buildings and in the acoustic refurbishment of existing rooms, where the low build-up height helps. Also used in humid rooms and weather-protected outdoor areas.
