The external insulation rock wool board is specially designed and produced for the building external thermal insulation thin plaster system. It is used for the building’s dense external wall insulation such as concrete or brick walls or energy-saving transformation of existing buildings. In addition, the outer wall thermal insulation rock wool lamella can also be used as a fire barrier, and it can be used with thermal insulation materials whose combustion performance does not reach Grade A to improve the fire protection function of the building's external wall.
External insulation rock wool board is Grade A non-combustible fire proof insulation material. It has high compressive strength and tensile strength, low water absorption rate, stable dimension, doesn’t have thermal expansion or contraction, aging resistant, etc. It doesn’t corrode other parts of external wall insulation system, provides effective heat preservation, energy saving, fire protection and extreme weather protection for the building.
External insulation rock wool board has below characteristics:
1. High compressive, tensile strength and durability, ensure the long-term stability and reliability of product performance.
2. Rock wool does not burn, does not release heat and toxic smoke, and can effectively block the spread of flame when a fire occurs, and has excellent fire resistance.
3. Superior thermal insulation performance can increase the thermal resistance of the building envelope, reduce the energy consumption of building heating and air conditioning.
4. No corrosion to metal materials such as carbon steel, aluminum (alloy), copper, and various components in buildings.
5. It has the physical characteristics of efficient sound absorption and noise reduction and elastic vibration reduction.
6. No moisture absorption, aging resistance, long-term stable performance.
7. Light weight, easy to cut and saw, easy to process.
Next issue we will continue to introduce construction process of
external insulation rock wool board. Please stay tuned.
