The main feature of acoustic tiles is their high sound absorption. These boards absorb some of the sound waves due to the conduction of sound through the holes in the tile to the space behind the false ceiling. If a layer of rock wool is used on the back of the tile, the sound absorption will be increased significantly. Acoustic tiles are often used in buildings such as cinemas, amphitheaters, banks, department stores, offices and educational spaces. Acoustic tiles with different categories of sound absorption criteria are produced as follows: Model 6/18 Model 8/18 Model 8/12/36 Model 8/12/50 Model 12/25 Acoustic tiles with PVC coating or without coating (to Plain or painted white) is produced and supplied. These tiles have a fleece layer on the back of the tile to prevent the collapse and diffusion of mineral wool particles. The color of the fleece layer is white or black depending on the customer’s request.
