Square Tile BC Tech MD is primarily designed to absorb medium and high frequencies. Sound energy crosses through the perforated wooden surface and is absorbed by the foam material underneath. 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 with a lacquered paint in black or white was built to achieve a strong and suitable product for the Building & Construction Market that has strong fire rating demands. Square Tile BC Tech MD can fit in standard 60 x 60 cm suspended ceiling frames.
