Shandong External Wall Insulation Material Manufacturer Share: The main types of external wall insulation materials are indispensable in the field of construction. Their main function is to reduce heat transfer and improve the energy efficiency of buildings. Below are several common exterior wall insulation materials.

Firstly, extruded polystyrene board (XPS) is a high-quality external wall insulation material. It has high strength, low density, and excellent insulation performance, which can effectively prevent the formation of cold and hot bridges.

Secondly, expanded polystyrene board (EPS) is also a common external wall insulation material. It has good insulation performance and low water absorption rate, and is relatively affordable, so it is widely used.

In addition, rock wool board, as an inorganic insulation material, has advantages such as fire resistance, thermal insulation, and sound absorption. It is suitable for high-rise buildings and places with high fire prevention requirements.

Moreover, glass wool products occupy a place in the field of building insulation due to their excellent insulation and sound absorption properties.

Finally, aluminum silicate insulation material is also worth mentioning as an external wall insulation material. It has excellent high temperature resistance and is suitable for building insulation in high-temperature environments.
