Effect of density of composite rock wool board on its performance

The density of the composite rock wool board is related to its thermal insulation quality. The density of the rock wool composite board used for different types of walls is different, because their fire rating is different. The density of the composite rock wool board has a certain degree of influence on its noise reduction effect. Composite rock wool board is a new type of material widely used in construction. Rock wool, calcium silicate board, glass fiber and other materials have become important materials for ship insulation. The structure of composite rock wool board has four layers, which are adhesive layer, Insulation layer, finishing layer, finishing layer and accessories.

With the development of construction technology, the application of composite rock wool boards has become more and more extensive, and the quality and use of products have also made great progress. It is more and more popular.

The density of the rock wool board has a great effect on the air pressure and air velocity, which has a certain effect on the noise reduction function of the rock wool board. When the density is higher, the air flow in the product is slower, and the sound absorption effect of the rock wool board can reach a better state. Therefore, the noise reduction effect of the rock wool composite board is very good, and this effect is also widely used in building insulation.
