Curtain wall fireproof insulation rock wool board
- Product details
-
Curtain wall fireproof and thermal insulation rock wool board is a professional research and development for curtain wall systems. It has the characteristics of higher fire resistance temperature, melting point, and smaller high-temperature linear shrinkage. At the same time, it has good hydrophobicity and moisture resistance, low moisture absorption and absorption rate, and will not corrode metals. Its fireproof performance reaches non combustible A1 level.
According to different usage locations and application purposes, there are two different series of curtain wall fireproof rock wool. One is used for fireproof and smoke barrier between curtain walls and floor slabs or partition walls, as well as for fireproof sealing of other types of building gaps (including gaps around pipes that pass through walls); Another is rock wool used for fire separation between upper and lower window walls in curtain wall systems, which improves the smoke barrier ability of rock wool. The product has composite fire-resistant veneers on both the upper and lower surfaces, which can be combined with different veneer products such as aluminum foil, fiberglass felt, and fiberglass cloth according to user requirements. This series of products not only has excellent fire and smoke insulation performance, but also has excellent noise reduction and insulation 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.
