The body shell of RV is made of PVC structural foam developed by our company. This design is the global pioneer in the RV field. PVC structural foam is 2 times the insulation performance of that polystyrene foam with the same thickness. The efficient insulation greatly reduces the chances of using car air-condition. Thus it is effective for energy efficiency, decrease of greenhouse gas emissions, and you can feel the nature's beautiful scenery in zero distance. At the same time, the PVC core material has high strength, good safety characteristics which can ensure the safety and reliability of the RV in harsh operating conditions.
