What is the sandwich panel, sandwich board what is the use of what the characteristics of sandwich panels

Answer:

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. Sandwich panels are a common product in the current building materials, not only good flame retardant and environmentally friendly Sandwich board English name: laminboard Sandwich panel products are composed of two layers of metal panels (or other material panels) and directly in the middle of the panel foam, mature molding of the composition of the polymer core insulation. These sandwich panels are easy to install, lightweight and efficient. Filling system is also used to close the molecular structure, you can put an end to the condensation of water vapor.
