Features: Rock wool sound-absorbing ceiling tile, its best performance is thermal insulation, combustion & sound insulation performance. Rock wool is an inorganic fiber made of natural rock such as basalt, aluminum vanadium, etc. by melting and fiberizing at high temperature. 
1. Insulation performance Good thermal insulation is the basic characteristic of rock wool and slag wool products. Under normal temperature (about 25℃), their thermal conductivity is usually between 0.03～0.047W/(moK). 2. Combustion performance The burning performance of rock wool and slag wool products depends on the amount of combustible adhesive. Rock wool and slag wool are inorganic silicate fibers, which are non-flammable. In the process of processing into products, organic binders or additives are sometimes added, which will have a certain impact on the combustion performance of the products. 3. Sound insulation performance Rock wool and slag wool products have excellent sound insulation and sound absorption properties. The sound absorption mechanism has a porous structure. When sound waves pass through, friction due to the effect of flow resistance causes part of the sound energy to be absorbed by the fibers, hindering the transmission of sound waves.
