With the promotion and implementation of building energy-saving policies, the application of exterior wall insulation materials in the construction field is becoming more and more extensive. Among them, extruded polystyrene board, as a new type of insulation material, has received widespread attention from the industry due to its excellent performance and broad application prospects. This article will give a detailed introduction to the performance, application field and development trend of extruded polystyrene board, an exterior wall insulation material.

1. Performance characteristics of extruded polystyrene board, an exterior wall insulation material

1. Good thermal insulation performance: extruded polystyrene board has a lower thermal conductivity, and its thermal insulation performance is better than traditional EPS and XPS insulation boards. According to statistics, the thermal conductivity of extruded polystyrene board is 0.028W/(m·K), while the thermal conductivity of EPS and XPS insulation boards is 0.041W/(m·K) and 0.030W/(m·K), respectively. Therefore, extruded polystyrene board can significantly reduce energy consumption while ensuring the insulation effect of the building.

2. Excellent compressive performance: extruded polystyrene board has been specially processed and has high compressive strength and can withstand large loads. According to test data, the compressive strength of extruded polystyrene board can reach more than 250KPa, which is much higher than the compressive strength of EPS and XPS insulation board. This makes extruded polystyrene board have a longer service life in the exterior wall insulation system.

3. Good waterproof performance: Extruded polystyrene board adopts closed-cell structure and has good waterproof performance. Its water absorption rate is very low and it almost does not absorb water, so it can still maintain good insulation performance in a humid environment. In addition, extruded polystyrene board also has good anti-penetration performance, which can prevent moisture from penetrating into the wall and ensure the durability of the building.

4. Good fire resistance: Extruded polystyrene board is made of inorganic materials, does not burn, and does not produce toxic and harmful gases at high temperatures. According to national standards, the combustion performance of extruded polystyrene board reaches B1 level and is a flame-retardant material. Therefore, extruded polystyrene board has higher safety in the exterior wall insulation system.

5. Good environmental performance: Extruded polystyrene board adopts environmentally friendly production process, does not produce harmful substances, and does not pollute the environment. In addition, extruded polystyrene boards have good recycling value and can reduce the cost of waste disposal after the demolition of buildings.

2. Application fields of extruded polystyrene boards for exterior wall insulation materials

1. Residential buildings: Extruded polystyrene boards are widely used in the exterior wall insulation system of residential buildings, which can improve the insulation performance of buildings, reduce energy consumption, and improve living comfort.

2. Public buildings: Extruded polystyrene boards can also be used in the exterior wall insulation system of public buildings, such as office buildings, shopping malls, hotels, etc. These buildings usually have high requirements for insulation and fire resistance, and extruded polystyrene boards just meet these requirements.

3. Industrial buildings: Extruded polystyrene boards can also be used in the exterior wall insulation system of industrial buildings, such as factories, warehouses, etc. These buildings usually have high requirements for insulation and compressive resistance, and extruded polystyrene boards have obvious advantages in these aspects.

4. Green buildings: With the promotion of the concept of green buildings, the application of extruded polystyrene boards in green buildings is becoming more and more extensive. The environmental protection and energy-saving performance of extruded polystyrene boards make them an ideal choice for green buildings.

3. Development trend of extruded polystyrene boards for exterior wall insulation materials

1. Product diversification: With the continuous growth of market demand, the product types and specifications of extruded polystyrene boards will continue to be enriched to meet the insulation needs of different types of buildings.

2. Technological innovation: Extruded polystyrene board manufacturers will continue to increase investment in technology research and development, improve product performance and reduce costs through technological innovation to enhance market competitiveness.

3. Green and environmental protection: Extruded polystyrene board manufacturers will further improve the environmental protection performance of products, reduce pollutant emissions in the production process, and reduce the impact on the environment.

4. Industrial integration: With the intensification of market competition, the extruded polystyrene board industry will be further integrated, the survival of the fittest, and form a group of large-scale and competitive enterprises.

In short, as a new type of exterior wall insulation material, extruded polystyrene boards for exterior wall insulation will play an increasingly important role in the field of building energy conservation with their excellent performance and broad application prospects. At the same time, extruded polystyrene board manufacturers will also face greater market challenges and development opportunities, and need to continue to innovate and develop to meet market demand.
