Good noise reduction performance is an important consideration for modern architecture. The BD punched sound absorbing composite panel achieves the goal of reducing noise inside and outside the building by changing the variety of the insulating core material and the punching treatment of the surface steel plate.
A lot of interconnected fine spaces inside the sound absorbing material, so that the sound wave vibration energy is converted into heat energy and absorbed;
Through the regular punching steel plate on the metal plate, the incident sound wave oscillates in the cavity with the small bottom and the bottom, the sound wave collides with the bottom wall and the bottom surface of the cavity, and the sound waves collide with each other, consuming sound energy, thereby absorbing sound. effect;
Superior fire performance, the fire resistance limit of rock wool board can be up to 240 minutes, and the fireproof performance grade of polyurethane board can be made up to BI grade;
The installation is quick and convenient, horizontally and vertically.
