ZRD Exterior Wall Rock Wool Board External wall insulation rock wool board is mainly used as thermal insulation material in external wall insulation thin plastering system and dry-hanging curtain wall insulation system. It has good compressive strength, tensile strength perpendicular to the surface, and excellent hydrophobicity. It is suitable for For various base walls. It can be used not only for external thermal insulation of newly built and expanded walls, but also for energy-saving renovation of external thermal insulation of existing buildings. Class A non-combustible fire rating and high resistance to high temperature shrinkage can maintain the stability of the system structure in the event of a fire. The exterior walls and roof form the building envelope, protecting everyone and everything inside.
They also have the largest surface area, making them the prime area for preventing heat loss. The main places for heat loss are poorly insulated walls. External wall insulation systems meet modern building standards while gaining additional benefits in terms of acoustics, interior comfort and fire safety. Rock wool for external wall insulation is in the field of Class A fireproof materials. Because of its unique environmental protection and energy-saving performance, there is no new product that can completely replace rock wool in the current industry.
The Advantages of Exterior Wall Rock Wool Board:
1.Satisfy the highest fire protection level, fire protection class A.
2. Non-combustible, does not release toxic fumes, green performance.
3. The compressive and tensile strength meet the requirements of the external wall insulation standard, and the strength standard is highly consistent with the external wall standard.
4. Good thermal insulation performance and long-lasting stability.
5. With excellent air permeability and convenient construction, it has become the preferred choice for building exterior wall construction parties.
6. Strong resistance to high temperature shrinkage, it can maintain the stability of the system structure in case of fire, and ensure the stability of the building in case of accidents.
7. It has the physical characteristics of high-efficiency sound absorption and noise reduction and elastic vibration reduction, which meets the requirements of modern buildings.
8. Lightweight, can be cut and sawed, easy to process, and convenient for on-site construction.
9. No corrosion to metal materials and various components in buildings, and the structure is stable.
10. The fiber is non-toxic, safe to use, and environmentally friendly.

Application
When applying the rock wool external thermal insulation thin plastering system, try to avoid the use of ceramic tiles, high-elastic paint and other vapor-impermeable finishing materials, so as to give full play to the vapor permeability of rock wool and avoid building mildew and condensation.
