In the construction industry, wall insulation is a crucial link. With the development of technology and the deepening of environmental protection concepts, new types of exterior wall insulation materials have emerged like mushrooms after rain. Among them, extruded polystyrene board has become a popular product in the market due to its excellent insulation performance, environmental performance, and convenient construction. This article will provide a detailed introduction to extruded polystyrene board, in order to help more people understand and recognize this new type of external wall insulation material.

1、 Overview of extruded polystyrene board

Extruded polystyrene foam board, full name of extruded polystyrene foam board, is a rigid foam plastic board with closed cell structure, which is made of polystyrene as the main raw material by heating and extrusion. Its surface is flat, the internal structure is stable, and it has good insulation performance, compressive strength, and weather resistance.

2、 Excellent performance of extruded polystyrene board

1. Thermal insulation performance: The closed cell structure of extruded polystyrene board gives it a low thermal conductivity, which can effectively prevent heat transfer and achieve good insulation effect. At the same time, its internal structure is stable and not prone to thermal expansion and contraction, ensuring the stability of the wall.

2. Compressive strength: Extruded polystyrene board has high compressive strength and can withstand large pressures without deformation, making it suitable for external wall insulation of various buildings.

3. Weather resistance: Extruded board has good weather resistance, can resist wind and sun exposure, is not easy to age, and has a long service life.

4. Environmental performance: The production process of extruded boards does not produce harmful substances and does not pollute the environment. At the same time, its waste can be recycled and reused, which conforms to the concept of green environmental protection.

5. Convenient construction: The size of the extruded board is stable, easy to cut, and the construction is convenient and fast. Meanwhile, it is lightweight and easy to transport and construct.
