What is the difference between the ecological board and the sandwich board? Which is used to decorate better, what is the price? What are the top ten brands of the two boards?
The ecological board is made of natural mineral stone powder and natural fiber as the basic raw material, through the inorganic gel technology modification process, through the mold, natural curing molding for the environmental protection and energy saving new materials, which does not contain formaldehyde, toluene inorganic natural environmental performance, Combined with the surface of the natural texture and sustained and efficient negative oxygen ion release, to achieve its natural properties of green building materials. Sandwich panels, composed of two layers of metal panels (or other material panels) and directly in the middle of the panel foam, mature molding of the polymer core insulation composition, easy to install, light and efficient. Filling system is also used to close the molecular structure, you can put an end to the condensation of water vapor.
