Rockwool boards are primarily made from basalt, which is melted and then spun into non-stop fibers of 4-7um using a four-roller centrifugal spinning process. Subsequently, a certain amount of binder, dust-proof oil, and water-repellent agent are added to the rockwool fibers. After settling, curing, and cutting, a series of products with different densities are produced according to various applications.

Rockwool board applications:
Rock wool thermal insulation boards are primarily used for fireproof and soundproofing in building partition walls and curtain walls, roof and protective structures insulation, geothermal system insulation; as well as for thermal and fireproofing purposes in industrial furnaces, ovens, large-diameter storage tanks, and ships.
Rockwool board properties
1. Insulation Performance: Good thermal insulation is a fundamental characteristic of rock wool and slag wool products. Under normal temperature conditions (around 25°C), their thermal conductivity is typically between 0.03 to 0.047 W/(m·K).
2. Combustion Performance: The combustion properties of rock wool and slag wool products depend on the amount of combustible binder used. Rock wool and slag wool are inorganic silicate fibers themselves and are non-combustible. During the processing of rock wool boards into finished products, organic binders or additives may sometimes be added, which can affect the combustion properties of the finished products.
3. Sound Insulation: Rock wool and slag wool products offer excellent sound insulation and absorption properties. Their absorption mechanism is due to their porous structure, which, when sound waves pass through, generates friction due to flow resistance, causing part of the sound energy to be absorbed by the fibers and thus obstructing the transmission of sound waves. Consequently, rock wool boards have good sound insulation and noise reduction capabilities.
Method of installation for mineral wool rock wool boards:
In building energy conservation, the installation of mineral wool mainly falls into two categories: dry-hanging and adhesive.
Dry hanging is mainly used for matching exterior glass curtain walls, stone curtain walls, etc., serving as insulation material in the framework. Due to the heavy weight and slightly lower internal strength of mineral wool boards, there are several points to note during construction. Firstly, it is essential to use galvanized wire mesh for protection and to secure with insulation nails. For mineral wool products with significant weight, consider the construction process to avoid deformation caused by excessive weight.
