Product Description:
Polyurethane(PU)roof sandwiched panel is composed of 2 layers of colored steel sheets and injected hard forms of polyurethane between 2 layers which feature fireproof materials. It is suitable for the various roofs and walls referring to the large-size factory buildings, storages, exhibition halls, gymnasiums, freezing stores, purifications workshops, etc, which features temp-keeping, heat insulation, weight-bearing, weatherproof with the rich colorfulness and good Appearance
Polystyrene Foam Sandwich Panels also called PU Sandwich Panel, the up & down surface of this panel is Galvanized & Pre-painted steel sheets, core material is 5 components Polyurethane glue, it is formed by heating, foaming & laminating. Polyurethane is the best material for temperature keeping and sound insulation.
Advantages:
1. Light in weight
2. Heat-insulation, good sound insulation
3. Good durability,
4. Fireproof
5. Competitive in price
6. Hot-dip Galvanized Steel Sheets then Color Coated
7. Sound insulation
Characteristics of PU insulated panels:
1.Sandwich wall/roof panel has the following characteristics: light dead weight, high mechanical strength, excellent shearing resistant performance, strong corrosion resistance, high durability, and weather fastness, etc.
2.The sandwich panel has excellent insulated performance: heat insulation, sound insulation, waterproof performance, etc.
3.It is easy to install and can be used times over.
