Acoustic Baffle

EPD availableFree-hanging

Description

Vertical metal baffle for open ceiling installations, available in one-piece or two-piece versions. The acoustic performance can be tuned to the room by adjusting baffle height, baffle spacing, and suspension height. The structural ceiling and built-in services remain visible and accessible for maintenance at all times. At shallow viewing angles, the baffles also provide glare reduction; lighting can be integrated between or into the baffles. Can be combined with a cooling and heating function. Design flexibility through variation of height, arrangement, and colour. 74 tested configurations, baffle heights from 40 to 600 mm.
