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

Product Specifications: Customizable as per requirement.

Rockwool board applications:

Rock wool insulation boards are primarily used for fireproof and soundproofing in building partition walls and curtain walls, thermal insulation for roofs and protective structures, ground-source heating system insulation; thermal and fireproofing for industrial furnaces, ovens, large-diameter storage tanks, and ships.

Rockwool board properties

1. Insulation Performance: Good thermal insulation properties are a fundamental characteristic of rock wool and slag wool products. Under normal temperature conditions (around 25°C), their thermal conductivity is typically between 0.03～0.047 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 themselves are inorganic silicate fibers and are non-combustible. During the manufacturing process of rock wool boards into finished products, organic binders or additives may sometimes be added, which can have an impact on the combustion properties of the finished products.

3. Soundproofing Performance: Rock wool and slag wool products exhibit excellent soundproofing and noise absorption properties. The absorption mechanism lies in their porous structure, which, when sound waves pass through, generates friction due to flow resistance, causing a portion of the sound energy to be absorbed by the fibers, thus hindering the transmission of sound waves. Therefore, rock wool boards offer good soundproofing and noise reduction capabilities.

Installation Method of Mineral Wool Rock Wool Boards:

In building energy-saving applications, the installation of mineral wool primarily 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 a heavy self-weight, consider the construction process to avoid deformation caused by excessive weight.
