The thermosetting polystyrene board in the community is 490 wall, with excellent insulation effect and good heating. The room temperature was not lower than 26℃ before the renovation, and the temperature increased by 2℃ after the renovation. It is also necessary to consider the thermal conductivity of the wall structure of the thermosetting polystyrene board. If the thermal insulation performance of the material is the same, it is recommended that you choose to buy thermosetting polystyrene board materials with lower thermal conductivity, so that the construction is more convenient and does not take up space.

Thermosetting polystyrene board can protect the main wall structure of the building and extend the service life of the building. Because the external insulation is the insulation layer outside the structure, it reduces the pressure caused by the deformation of the structure due to temperature changes and reduces the erosion of the structure by substances in the air and ultraviolet rays.

When constructing the thermosetting polystyrene board mortar, avoid direct sunlight. If necessary, a sunscreen can be set up on the construction scaffolding to block the construction wall. During the surface construction, the on-site ambient temperature and the surface temperature of the base wall should not be lower than 5℃, and appropriate protective measures should be taken during winter construction. The performance difference between extruded board and polystyrene board also leads to differences in their operating ranges. Extruded boards are often used for roof insulation, basement and floor insulation, while polystyrene boards are widely used in the field of building energy conservation and insulation.

The walls of thermosetting polystyrene boards have sufficient working capacity to buffer external impact forces according to the changes and repairs of the appearance; thermosetting polystyrene boards adopt a single bubble structure with a small total area and are not easy to affect all walls. Its surface water absorption rate is low and its impermeability grade is good, which can effectively prevent problems such as cold mold and collapse after the wall is damp. Related knowledge about the flammability of polystyrene foam boards and the skills of purchasing exterior wall insulation boards. Polystyrene foam boards have good thermal insulation performance and are widely used.
