Rock wool board is an artificial inorganic fiber processed by high-temperature melting. It has the characteristics of lightweight, low thermal conductivity, heat absorption, and non-combustibility. The initial development is a common application type in construction and is mostly used in industrial buildings.

Rock wool
Rock wool is a kind of external thermal insulation material. When organic thermal insulation materials with a market share of 90% are stagnating, rock wool, as an inorganic material for exterior wall thermal insulation that has achieved fire rating A, has ushered in an unprecedented market opportunity.The price of rock wool has soared from around 42 yuan/square meter to 200 yuan/square meter. Even so, market demand still exceeds supply.
The policy adjustment is the direct cause of the price increase of rock wool materials. With the occurrence of fires in Beijing, Shanghai, Shenyang and other places, the fire protection disadvantages of the large-scale use of external thermal insulation organic materials have been exposed. The Fire Department of the Ministry of Public Security issued the "Notice on Further Clarifying the Relevant Requirements for the Fire Supervision and Administration of Civil Building External Thermal Insulation Materials", incorporating civil building external thermal insulation materials into the scope of construction engineering fire protection design review, fire protection acceptance and filing and spot checks, and stipulating civil building external thermal insulation materials Should reach A level.
Features
- Fire prevention
The outer wall rock wool board is made of natural volcanic rock, which is a non-combustible building material and fireproof material.
Main fire protection characteristics:
☉ has the highest fire rating A1, which can effectively prevent the spread of fire.
☉ is very stable in size and will not stretch, shrink or deform in a fire.
☉High temperature resistance, melting point higher than 1000℃.
☉ does not produce smoke or burning droplets/fragments in a fire.
☉ will not release harmful substances and gases in the fire.
2.thermal insulation
The outer wall rock wool board has a slender and flexible fiber and a low content of slag ball. Therefore, the thermal conductivity is low and the heat preservation effect is excellent.
3.Sound absorption and noise reduction
Rock wool is an ideal sound insulation material. A large number of slender fibers form a porous connection structure, which determines that Shida rock wool is an excellent sound-absorbing and noise-reducing material.
4.Hydrophobicity
The water-repellent rate of water-repellent rock wool products can reach 99.9%; the water absorption rate is extremely low, and there is no capillary penetration.
5. moisture resistance
Rock wool has a volumetric moisture absorption rate of less than 0.2% in an environment with a high relative humidity. According to the ASTM1104 or ASTM1104M method, the mass moisture absorption rate is less than 0.3%.
6.Non-corrosive
Rock wool has stable chemical properties, with a PH value of 7-8, which is neutral or weakly alkaline, and has no corrosion to carbon steel, stainless steel, aluminum and other metal materials.
7.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 recognized as non-carcinogenic by the international cancer research authority)
