Glass wool is one of the most commonly used materials for building sound absorption because of its excellent properties of fire protection, heat preservation and easy cutting. But because the glass wool surface is not decorative, and there will be fiber sprinkled, so it must be made into a variety of sound absorption components hidden use. The most commonly used and cheapest structure is perforated paper gypsum board ceiling or made into a wall filled with centrifugal glass wool perforated board, the perforation rate is greater than 20%, can basically play a glass wool sound absorption performance. In order to prevent fiberglass from spilling out, it is necessary to attach a layer of non-woven fabrics, mulberry paper and other sound-permeable fabrics to the back of perforated panels, or wrap fiberglass with fiberglass cloth and plastic film. Similar to perforated paper gypsum board, perforated metal board (such as aluminum board), perforated wood board, perforated fiber cement board, perforated mineral wool board, etc.
