Calcium silicate perforated board is a new type of indoor sound-absorbing board product made of calcium silicate board as the base plate and perforated by punching equipment. It can be a standard size, or it can be cut according to the different requirements of customers.

The perforated calcium silicate board is easy to cut, simple and convenient for construction, and can adapt to the decoration requirements of different styles and levels. It has sound absorption function, stable function, not easy to deform, high non-combustibility, and a non-woven fabric on the back to prevent dust. It is suitable for commercial construction, industrial construction, residential construction, residential construction, public construction and decoration innovation and other places and constructions that require noise reduction.

Perforated sound-absorbing wall is generally composed of three parts: perforated sound-absorbing board, sound-absorbing material and air layer. When sound passes through the perforation of the perforated sound-absorbing panel and the fiber gap of the sound-absorbing material through sound waves, the sound waves vibrate violently due to resonance and rub against the air in the holes and fiber holes, causing part of the sound energy to be converted into heat energy and absorbed. Sound encounters obstacles and forms reflections. The once reflected sound is used to directly supplement the sound, the sound becomes thick and full. Part of the sound enters the pores when encountering holes. After several reflections in the cavity, some are reflected again to the outside. But the energy is already quite small at this time, and the other part decays in the cavity until it disappears.

Calcium silicate perforated board is a perfect acoustic interior material for sound proofing ceiling and wall projects. We could provide small samples if there is any need. Do not hesitate to contact us.
