Name: SUAM Baffle
Brand: SUAM Schall- & Akustikmanufaktur GmbH

Baffle

Free-hanging

Description

The SUAM Baffle is a vertically suspended single baffle made of thermally bonded polyester wadding. It is used when the structural ceiling should remain visible or installation levels must remain freely accessible. Depending on the baffle spacing and installation height, sound absorption ranges between αw 0.50 (Class D) and αw 0.75 (Class C). A greater installation height improves low-frequency absorption. Mounting: Single suspension, cable suspension, direct mounting on T-profile, magnet, or system fastening. Customizable colors.
