Sandwich Panel is a prefrontal, lightweight building material that consists of three layers:
- The Middle Layer (metal or sometimes fiberglass/aluminum)
- The middle layer (insulation kernel)
- The back layer (like the scroll layer)
This structure like a sandwich makes the panel both light and high.
The main components of the sandwich panel
Cumin sheet
- are usually made of galvanized sheets, aluminum or aluminum.
- Sometimes colored coating (polyester, PVDF, etc.) have a rust and beauty resistance.
The middle core (thermal and acoustic insulation)
- Polyurethane (PU): The best insulator, style and moisture resistant.
- Polyisocyanurat (PIR): PU -like but more resistant to fire.
- Polystyrene (EPS): Cheaper, Lightweight but Weaker Insulation High -heavier audio insulation.
