High Strengthen Heat Insulation Polyurethane PU Sandwich Wall Panel

 I. Brief Introduction of PU Sandwich Panel
  Polyurethane Sandwich Panel choose high quality two layer color coated steel or other precision forming metal as surface material. After rolling forming, it will inject flame retardant polyurethane bubble liquid in the middle space, through high pressure foaming and curing process, with strong adhesion with metal surface to compound and become beautiful, smooth, tough building panel.
II. Product Features
1)     Overcome the effect of cold and hot bridge
2)     Double seal waterproof design, good air tightness
3)     Hidden installation screw
4)     Dry hanging installation, high efficiency
5)     Applies for old building reconstruction, the application of texture effect
6)     Weather resistance, long life (double protection)
7)     Self clean, reduce maintenance costs
8)     Fireproof performance, external wall fireproof system
