1. From the perspective of thermal insulation effect
Because the main purpose of laying extruded plastic boards and foam boards is thermal insulation, the thermal insulation effect of the materials is very critical. As far as extruded board and foam board are compared, extruded board is made of polystyrene resin as the main raw material, and then made by a special process, with evenly distributed and tight pores on the surface, and good thermal insulation effect, while foam board is made of polystyrene. Beads are the main raw material, because the beads themselves have a certain elasticity, so the structure is not tight enough, and the thermal insulation effect is slightly poor.
2. From the perspective of load-bearing
The pore structure of the extruded board is evenly distributed. On the whole, the tightness is relatively good, while the foam board is composed of beads, because it is elastic and has no distributed pores inside, so in terms of load-bearing, the extruded board is superior. on foam board.
3. From the perspective of service life
Because the extruded board is made of resin, it has high hardness and good tightness, so it is not easy to deform, and the beads of the foam board have good elasticity, and it is easy to collapse, deform, or even break when stepped on. longer.
4. From the perspective of environmental performance
The water absorption of the extruded board is extremely poor, and it is not permeable to water, so after installation, it has very good moisture resistance. At the same time, because of the tight internal structure, it will not cause pollution and has high environmental protection performance. It is expanded by a special process, which is easy to burn, and will cause secondary pollution during the combustion process, so the environmental protection performance is poor.
