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 Cool is a seamless acoustic system that also heats and cools. Capillary tube mats are laid on bonded BASWA acoustic panels, embedded in a heat-conducting microporous filling layer and finished in two coats. Water flowing through the tubes heats or cools the room surface silently and without drafts, while the panels below absorb sound and insulate the tubes from the substrate. For horizontal, inclined, vertical and gently curved ceilings and walls in offices, schools, healthcare, hotels, restaurants, housing and humid rooms such as swimming pools, in new buildings and in refurbishment, including listed buildings.
