High strength roof insulation rock wool board
- Product details
-
High strength roof insulation rock wool board is specially used for various industrial and civil roof insulation systems. It not only has excellent thermal insulation, fire prevention and noise reduction performance, but also has excellent compression resistance, high load, aging resistance and weather resistance. When used together with perforated metal boards, it has obvious noise reduction effect and can effectively control the indoor reverberation time. It is an ideal choice for various building roof insulation systems.
High strength roof insulation rock wool board is often used in roof structural systems that require high compressive strength. As an insulation layer and load-bearing layer, it is combined with flexible waterproof rolls and breathable layers to form a roof insulation and waterproof structural system. Flexible waterproof roofs are also used in waterproofing systems for steel or concrete flat roof structures such as airports, train stations, various factories, commercial centers, exhibition centers, and sports venues.

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.
