Unisquare BC Tech Mel is primarily designed to absorb low and medium frequencies. Sound energy crosses through the perforated wooden surface and is absorbed by the foam material underneath. The perforated structure were studied in order to achieve an equal hole distance inside the panel and between panels, obtaining a more efficient helmotz ressonator. Wood finishing is generally regarded as a noble surface treatment in architectural spaces, critical listening rooms and performance spaces such as concert halls and other venues. This version in Tech foam and fire retardant MDF was built to achieve a strong and suitable product for the Building & Construction Market that has strong fire rating demands. Unisquare BC 60.4 Tech Mel can fit in standard 60 x 60 cm suspended ceiling frames.
