Rock wool board, also known as rock wool insulation board, is made of basalt and slag as the main raw materials, which are melted at high temperature to form inorganic fibers. Various specifications can be customized.
Size:
Width: 0.4m, 0.6m, 1m
Length: 0.6m, 1m, 1.2m, 2m, 2.2m, 2.4m
Density: 30kg/m3-200kg/m3
Thickness: 25mm-200mm
Features of rock wool board:
1. The raw material of rock wool is volcanic rock, with a fireproof grade of A1
2. Rock wool fiber is slender and flexible, with low slag ball content. Therefore, the thermal conductivity is low and has good thermal insulation effect.
3. There are a large number of slender fibers inside the rock wool, forming a porous connection structure, which can have the effect of sound absorption and noise reduction.
4. Rock wool is added with water repellent, the product has a water repellent effect and low water absorption rate.
5. The volume moisture absorption rate of rock wool is relatively low in an environment with high relative humidity.
6. Rock wool has stable chemical properties, a pH value of 7-8, and is neutral or weakly alkaline, which reduces the corrosion of metal materials such as carbon steel, stainless steel, and aluminum.
Rock wool board is used in building roofs, interior partitions, boiler insulation and other fields
