Rock wool board application

Oct. 12, 2019

The rock wool board is made of basalt and is made of high-melting inorganic fiber board. It has the characteristics of light weight, low thermal conductivity, heat absorption and Class A fire resistance.

First, it has the highest fire rating of A1, which can effectively prevent the spread of fire.

Second, the hydrophobic water-rock wool product has a water-repellent rate of 99.9%; the water absorption rate is extremely low, and there is no capillary penetration.

Third, the moisture resistance of rock wool in a relatively high humidity environment, the volume moisture absorption rate is less than 0.2%; according to ASTM C1104 or ASTM1104M method test, the mass moisture absorption rate is less than 0.3%.

Fourth, non-corrosive rock wool has stable chemical properties, pH value of 7-8, neutral or weakly alkaline, and no corrosion to carbon steel, stainless steel, aluminum and other metal materials.

Fifth, the safe and environmentally friendly rock wool is tested to contain no asbestos, CFC, HFC, HCFC and other environmentally harmful substances. Will not be corroded or produce mildew and bacteria. (The rock wool has been identified as a non-carcinogenic substance by the international cancer research authority.

Wide range of applications: Rock wool board is widely used in petrochemical, textile metallurgy, electric power transportation, construction agriculture and other fields.

Rock Wool Board For Sale

Rock Wool Board 

Rock wool board supplier today introduce the application of different rock wool boards.

1. The rock wool board for exterior wall insulation is designed and produced for the external thermal insulation system of the building. It is suitable for the external wall insulation or energy-saving renovation of new or existing buildings with dense structures such as concrete or brick walls. It has the highest fire rating A1 grade, and has the advantages of high pressure resistance and tensile strength, low water absorption and moisture absorption, good dimensional stability and aging resistance, etc., while it is fireproof and heat insulation, sound absorption and noise reduction. It is compatible with the external wall system and has the same life span as the building structure. It provides effective insulation, energy saving, fire protection and extreme weather protection for buildings.

2. The special rock wool board for roofing is a rock wool product which is designed and developed for all kinds of flexible waterproof roofing systems. It has good resistance to pressure and resistance to point load. Good water repellency, moisture resistance, low short-term water absorption and long-term moisture rate, good aging and weather resistance, physical stability and chemical stability. It can meet the needs of load bearing and related equipment during construction and maintenance of roofing system.

3. The rock wool board for curtain wall is designed for the curtain wall system. It has the characteristics of higher fire resistance temperature, higher melting point and smaller high temperature line shrinkage. It also has good water and moisture resistance, low moisture absorption and low water absorption. Corrosive to metals.

4. The fire resistance rock wool board is made of rock wool for the use of the isolation belt. It is cut into strips with thick rock wool board. When used, the fiber is perpendicular to the wall, which greatly provides the tensile strength of rock wool. In the EPS, XPS and other external wall insulation materials whose combustion performance is less than A1 grade, the fireproof performance and safety of the external thermal insulation system of the building are increased.
