The extruded board system is a flexible structure that can timely and fully release thermal stress. So the "point and frame" pasting method has a high cost-effectiveness, which is also a commonly used pasting method in engineering. A moisture-proof layer should be added on cold surfaces to prevent cold. Under low temperature conditions, use rock wool without resin for insulation. When the temperature exceeds 200 ℃, the insulation material must have appropriate external protection to prevent possible expansion from changing thickness and bulk density.

The adhesive strength of extruded polystyrene board does not fade and has good resistance to force and freeze-thaw, which can effectively prevent the erosion of buildings by harsh external environments and extend the life of buildings. It has the appearance and texture of natural stone, and can be customized with different patterns and colors according to needs.

The degree to which the flexible construction material of extruded board retains heat, and the degree to which this heat is gradually integrated into the environment through the material. Materials with high thermal inertia can delay human perception in environments with large temperature differences, and thermal inertia is closely related to areas with large temperature differences between morning and evening. In order to achieve carbon neutrality goals, energy conservation and emission reduction are carried out. The energy consumption of buildings is significant. In the field of energy conservation, building energy conservation is necessary and there is a lot of work to be done, one of which is to do a good job in insulation of the building envelope structure.

The flexible structure of extruded polystyrene board effectively avoids the damage to the structure caused by harsh weather conditions, buffers the stress generated by structural deformation due to temperature changes, reduces the erosion of harmful gases and ultraviolet rays in the air on the structural enclosure structure, and causes cracks and damage to the wall.
