Product Detail

Rock wool board, also known as rock wool thermal insulation decorative board, is an inorganic fiber board made of basalt as the main raw material and processed by high-temperature melting. It has the characteristics of light weight, low thermal conductivity, heat absorption and non combustion.

Rock wool sandwich panel is a kind of sandwich panel made from rock wool. Rock wool panel give full play to the unique properties of rock wool core materials, in fire prevention, thermal insulation, sound absorption and other aspects have significant effect. It is suitable for roofing, wall, ceiling and partition of steel structure workshop and simple movable room. In order to increase the strength of rock wool sandwich panel and realize the diversity of connection modes, polyurethane is often used as edge sealing to form polyurethane edge sealing rock wool sandwich panel.

Rock Wool Board

Features of rock wool board


①It has the highest fire rating of A1, which can effectively prevent the spread of fire.

②The dimensions are very stable and will not stretch, shrink or deform in a fire.

③High temperature resistance, the melting point is higher than 1000℃.

④ No smoke or burning droplets/debris in fire.

⑤ In a fire, substances and gases that are harmful to the environment will not be released.

Thermal insulation

The outer wall rock wool panel fiber is slender and flexible, and the content of slag ball is low. Therefore, the thermal conductivity is low, and it has an excellent thermal insulation effect.

Sound absorption and noise reduction

Rock wool is an ideal sound insulation material, and a large number of slender fibers form a porous connection structure, which determines that Shida rock wool is an excellent sound absorption and noise reduction material.


The water repellency rate of hydrophobic rock wool products can reach 99.9%; the water absorption rate is extremely low, and there is no capillary penetration.

Moisture resistance

In an environment with high relative humidity, the volume moisture absorption rate of rock wool is less than 0.2%. According to ASTMC1104 or ASTM1104M method, the mass moisture absorption rate is less than 0.3%.


Rock wool has stable chemical properties, PH value is 7-8, neutral or weakly alkaline, and is suitable for carbon steel, stainless steel,Metal materials such as aluminum are non-corrosive.

Safety and environmental protection

Rock wool has been tested and does not contain asbestos, CFC, HFC, HCFC and other substances harmful to the environment. Will not be corroded or produce mildew and bacteria. (Rock wool has been identified as a non-carcinogenic substance by the International Agency for Research on Cancer)
