Buy good quality high insulation and durable and low price PU Foam Polyurethane Insulated Composite Sandwich Panels for Cold Storage Wall and Roof. Steel finishes available in Aluminium, Galvanized Steel, Painted Steel, Stainless Steel.
 
PU Sandwich Panel (Polyurethane Sandwich Panel) is composed of 2 layers of weather proof coloured covering sheets as per desired materials mainly steel, aluminium, coloured steel, or stainless steel, and jetted the hard forms of polyurethane between the two layers. It is also a fireproof materials. It is suitable for the various roofs and walls referring to the large-size factory buildings, cold storage, exhibition halls, gymnasiums, freezing stores, purification workshops, etc, which features temp-keeping, heat insulation, weight-bearing, weatherproof with the rich colourfulness and good appearance.
 
PU cold storage room panel is a kind of board used for enclosing structures, which has good heat insulation and higher intensity. 
 
It can reduce the heat transmission caused by difference in the internal and external temperature, and get to maximum efficiency of freezing and refrigeration systems. 
 
Heat insulation material for lower construction cost. Panels are in multiple varieties and specifications to meet the need of various sites and projects. 

The features of PUR insulation panel: Good heat conductivity, great water absorption, good in temperature preservation performance, excellent compressive strength and tensile strength, not easy to deformation, it is widely used in maintaining the combination of cold storage structure.

It can be widely used as the structural material and heatproof material in petroleum industry, chemical industry, construction, packing, refrigeration, military industry, space industry, aviation, transportation, industrial model design and so on.
 
Features:
1. Heat and sound insulation. Temperature suitable for PU ranges from -200 centigrade to 150 centigrade.
2. Good chemical resistance, waterproof, anti-corrosion, insect-free etc.
3. Advanced Tech: Automatic rolling machines make the whole process of manufacture effective.
4. Energy conservation, environmental protection, economical, heat insulting, good structure, easy-doing construction
5. Light weight enough to reduce building expense.
6. Time can be saved on a building project due to the simple installation.
