Today we are talking about several technical index of mineral fiber ceiling board.

1.Firstly, we are talking about NRC. NRC is the abbreviation of noise reduction Coefficient. The noise reduction coefficient refers to the arithmetic average of the sound absorption coefficient of the material at the center frequency of 250Hz, 500Hz, 1000Hz and 2000Hz, accurate to two decimal places, and the last digit is 0 or 5, which is expressed by NRC. Obviously, the larger the noise reduction coefficient, the better the sound absorption effect and the better the acoustic performance.

2.Secondly, it is CAC, Ceiling Attenuation Class. The CAC index is a measure of the sound insulation of adjacent spaces. The higher the CAC index, the better the acoustic performance.

3.Next, it is light reflectivity. Mineral fiber ceiling board are mostly used in office environments. For offices, most of the ceilings are mainly white color. If the ceiling has high light reflectivity, the entire office will be more brighter and effectively reduce visual fatigue. Long-term use of low-reflectivity ceilings can cause visual fatigue.

4. The last one is resistance of humidity. Moisture resistance coefficient is an important parameter of mineral fiber ceiling board quality. In some areas, it is rainy and humid all year round, so when choosing ceiling, we must pay attention to using mineral fiber ceiling board with high RH. Do not choose products with low RH for cheap, so as to avoid sinking after installed.

The above indicators can help us to better choose mineral fiber ceiling board. It is true that mineral wool boards are mostly used in office buildings and can be seen everywhere in the office. On the one hand, this kind of ceiling is not harmful, on the other hand, it has a good sound absorption effect. More importantly, this kind of material is very cheap and can help reduce the project budget. It is an ideal decorative material.
