There are various types of waterproof and thermal insulation materials for exterior walls

With the rapid development of the construction industry, the selection of exterior wall waterproof and insulation materials has become increasingly important. There are various types of exterior wall waterproof and insulation materials on the market, each with its unique performance and application scenarios. The following will provide a detailed introduction to several common exterior wall waterproof and insulation materials.

1、 Polystyrene foam board (EPS)

Polystyrene foam board is a common thermal insulation material with good thermal insulation performance and relatively low price. Its closed cell structure can effectively prevent water infiltration, thus playing a certain waterproof role. EPS board is suitable for external wall insulation systems of various buildings.

2、 Extruded polystyrene foam board (XPS)

Extruded polystyrene foam board is a more efficient thermal insulation material developed on the basis of EPS. It has a lower thermal conductivity, better insulation effect, and higher compressive strength. XPS board also has good waterproof performance and is widely used for external wall insulation of high-rise buildings.

3、 Rock wool board

Rock wool board is an inorganic fiber insulation material made by processing natural ores such as basalt through high-temperature melting. Rock wool board not only has good thermal insulation performance, but also excellent fire resistance. Its low water absorption rate and certain waterproof effect make it suitable for building exterior wall insulation with high fire resistance requirements.

4、 Polyurethane insulation board

Polyurethane insulation board is a polymer synthetic material with excellent insulation and waterproof properties. Its closed cell structure can effectively prevent water infiltration and has high compressive strength, making it suitable for building exterior wall insulation under various climatic conditions.

5、 Perlite insulation board

Perlite insulation board is a lightweight insulation material processed from perlite as the main raw material. It has a low thermal conductivity, good insulation effect, and a certain sound absorption effect. Perlite insulation board has a low water absorption rate and can be used for external wall insulation and waterproofing.

In summary, selecting appropriate exterior wall waterproof and insulation materials is crucial for improving the thermal insulation and waterproof performance of buildings.
