Exterior wall insulation rock wool board
- Product details
-
The exterior wall insulation rock wool board is designed and produced specifically for the thin plastering system of building exterior wall insulation. It meets the energy-saving requirements of new buildings and is also suitable for the energy-saving renovation of existing buildings' exterior walls. It has the advantages of high vertical tensile strength, low thermal conductivity, high hydrophobicity, good dimensional stability and chemical stability, and is particularly suitable for insulation and fire prevention of dense structures such as brick or concrete foundation walls. At the same time, this product can be used as a fire isolation belt to match the external wall insulation system, which can overcome the impact of extreme climate change, improve the overall insulation effect and fire safety of building external walls.
Exterior wall insulation rock wool board is mainly used in exterior wall insulation thin plastering systems and dry hanging curtain wall insulation systems, and can be applied to various dense wall building surfaces. The high compressive strength and high tensile strength of the product ensure its stability in application; High hydrophobicity and low water absorption ensure the durability of the product's application, while low thermal conductivity can effectively reduce the loss of cold and heat energy in buildings, achieving energy-saving and low-carbon emission reduction effects.

common problem
Q
What are the main types of building insulation materials? What are the advantages and disadvantages of each?
A
Advantages: Good fire resistance (Class A non combustible), good breathability, and high stability.
Disadvantages: Slightly higher thermal conductivity than organic materials, higher water absorption rate, and easy generation of fiber dust during construction.
Organic insulation materials (such as EPS polystyrene board, XPS extruded board, PU polyurethane):
Advantages: low thermal conductivity, good insulation effect, light weight, and convenient construction.
Disadvantages: The fire rating is mostly B level (requiring the addition of flame retardants), it is prone to deformation at high temperatures, and its durability is slightly poor.
Composite insulation materials (such as integrated insulation board, vacuum insulation board):
Advantages: Excellent comprehensive performance, high construction efficiency, and some can achieve Class A fire protection.
Disadvantages: High cost and strict requirements for the flatness of the base layer.
Q
How to choose insulation materials suitable for the project?
A
Fire prevention requirements: Grade A materials are required for high-rise buildings (>100m); Low level B1 (flame retardant) is available.
Climate conditions: In extremely cold regions, materials with low thermal conductivity (such as PU, XPS) are preferred; Low water absorption is required in humid environment (such as XPS, foam glass).
Base type: Concrete walls often use boards; Complex shapes can be coated with polyurethane or insulated mortar.
Economy: EPS has the lowest cost; Vacuum insulation board is expensive but thin.
Policy and regulations: B2 level materials are prohibited in some areas, and local standards need to be consulted.
