Rock wool boards are primarily made from basalt, which is melted and then spun into discontinuous fibers of 4-7um using a four-roll centrifugal spinning process. These fibers are then mixed with a certain amount of binder, dust-proof oil, and hydrophobic agent. After settling, curing, and cutting, a series of products with different densities are produced for various applications.

Product Specifications: Customizable to your requirements.

Rockwool Board Applications:

Rock wool thermal insulation boards are mainly used for fireproof and soundproofing in building partition walls and curtain walls, thermal insulation for roofs and protective structures, and thermal insulation for ground heating systems. They are also used for industrial furnace insulation, ovens, large-diameter storage tanks, and ship insulation and fire protection.

Rockwool board performance

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 and 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 products.

3. Soundproofing Performance: Rock wool and slag wool products possess excellent soundproofing and sound-absorbing properties. The sound-absorbing mechanism is due to the porous structure of these products, where, when sound waves pass through, friction is generated due to flow resistance, causing a portion of the sound energy to be absorbed by the fibers, thus obstructing the transmission of sound waves. Therefore, rock wool boards offer good soundproofing 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 primarily used for matching the exterior glass curtain walls, stone curtain walls, etc., serving as insulation material within the framework. Due to the heavy weight and slightly lower internal strength of mineral wool boards, there are several points to be aware of during construction. Firstly, it is mandatory to use galvanized wire mesh for protection, and insulation nails must be used for fixation. For mineral wool products with a heavier weight, the construction process should also be considered to avoid deformation caused by excessive weight.
