Mineral wool decorative sound-absorbing board is referred to as mineral wool board. It is made of granular cotton (made by smelting industrial waste and high temperature melting) as the main raw material, adding other additives, and going through the processes of batching, forming, drying, embossing, coating, cutting, etc.

Mineral wool board is a kind of porous material, interwoven into countless micro pores by fibers, sound waves hit the surface of the material and part of it is reflected back, part of it is absorbed by the board, and the other part of it enters the back cavity through the board, which greatly reduces the reflected sound, effectively controlling and reducing indoor reverberation time. NRC is a parameter indicating the sound absorption performance of a material. The NRC of mineral wool board is generally between 0.5 and 0.7. If asking for higher NRC requirement, we could recommend fiber glass ceiling tile for you, its NRC rate could be 0.9-1.0.

Fire resistance is the primary concern in the design of modern public buildings and high-rise buildings. The mineral wool board is made of non-combustible granular cotton as the main raw material. It will not burn in the event of a fire, which can effectively prevent the spread of fire. Moreover, due to its small deformation and long fire resistance time, it can fully extend the escape time and is the most ideal fireproof ceiling material. Also fiber glass ceiling tile is fire resistant ceiling material.

All high-quality mineral wool boards have moisture-proof performance, and will not be deformed or moldy after long-term use. For example, mineral wool boards with moisture-proof coefficients of RH85, RH90, and RH99 respectively represent the ability to resist deformation in an environment with a relative humidity of up to 85%, 90%, and 99% and room temperature below 40°C (104°F). The higher the number, the better the moisture resistance.
