Features:
1. Thermal insulation: rock wool fiber is slender, flexible and low thermal conductivity, which can improve the thermal resistance of building envelope, reduce heating and air conditioning energy consumption and improve energy-saving effect.
2. Acoustic noise reduction: the porous structure formed by rock wool fiber provides effective acoustic noise reduction and elastic vibration, eliminates physical characteristics and protects the wall from damage.
3. Fire protection: the fire resistance rating of rock wool is class A, that is, the melting point is higher than 1000 ℃. It will not release heat and toxic smoke, can prevent flame spread, has high size and stability, and will not deform in case of fire.
4. waterproof and moisture proof: rock wool waterproof 99%, low water absorption, no capillary penetration, waterproof and anti-aging.
5. Non corrosive: rock wool is chemically stable, neutral or weakly alkaline, and will not corrode with carbon steel, stainless steel, aluminum or other metal materials.
6. Health and environmental protection: rock wool will not rot, mildew and reproduce after long-term use. Rock wool does not contain asbestos and CFC chlorofluorocarbons,HFC trifl uoromchtanc or other harmful substances.
7. Performance stability: over time. Rock wool will not bend or deform and can be used as the most stable base material to ensure high standard waterproof and resist adverse base stress.
8. Stability: rock wool has high compressive strength and reinforcement strength to ensure the long-term stability and reliability of the product.
Applications :
. For external thermal insulation system ;
. For non - transparent curtain wall insulation system ;
. For the external thermal insulation system as a fire barrier around buildings or fire stopping beam ;
· For the systems which have a high requirement for fire protection , insulation and water repellence .
