External wall insulation materials can be divided into three categories based on their materials: inorganic insulation materials, organic insulation materials, and composite insulation materials. Mainstream materials in different categories have clear performance characteristics and applicable scenarios.

1、 Inorganic insulation material

Rock wool board: Made from natural minerals such as basalt, it is an A-level non combustible material with excellent fire resistance, insulation, and sound absorption properties. It has strong chemical stability and a long service life, making it suitable for use in densely populated areas and high-rise building exterior walls. Fiber protection should be done well during construction.

Foam glass: extremely high closed cell rate, almost no water absorption, outstanding waterproof performance, high strength, not easy to deform, good sound insulation effect, suitable for building exterior walls with high requirements for moisture-proof, but the disadvantage is that the production process is complex and the cost is high.

Other categories: foam cement, foam ceramics, traditional thermal insulation mortar, etc., with excellent temperature and chemical stability, non-toxic and non radioactive, can effectively block the cold and hot bridges.

2、 Organic insulation material

EPS polystyrene foam board: easy to handle and construct, good thermal insulation performance, high cost performance ratio, is one of the most widely used categories in the construction field. Its disadvantage is poor fire resistance, low strength and easy to damage.

XPS extruded polystyrene foam board: the compressive strength is much higher than EPS board, the thermal insulation effect is better, the water absorption rate is very low, and the moisture resistance is good. It is suitable for the roof, ground and other places with high load requirements, and also has the problem of insufficient fire resistance.

Other categories: it also includes phenolic foam, rigid foam polyurethane, etc. The thermal conductivity is low, the thermal resistance is high, and the thermal insulation effect is excellent. The spraying polyurethane has strong integrity and no gaps, and is suitable for surface construction of complex structures.

3、 Composite insulation material

Phenolic board: Combining the advantages of organic and inorganic materials, it has good insulation performance and is a non combustible material. It has chemical stability and is not easily aged, and has good sound insulation effect. However, its disadvantages are high production process requirements and high cost.

Other categories: including metal sandwich panels, vitrified microbeads, etc. vitrified microbeads have low water absorption and are resistant to high and low temperatures, making them high-quality lightweight aggregates for insulation mortar; Metal sandwich panels are lightweight and easy to install, with balanced insulation and structural strength performance.

Based on your previous focus on the demand for external wall insulation materials, suitable materials can be selected for different scenarios according to the building's fire rating, insulation requirements, and budget conditions.
