75mm Cold storage room PIR/PUR wall insulated sandwich panels
1.PU foam wall panels type:☆ Tongue and groove joint wall panels:
Panel effective width: 920/1000/1120 mm
Thickness: 75/ 100/ 150/ 200/ 250 mm
This panel type ensure the joint tightness,and the insulation performance of cold room.
2.Sandwich panel wall applications:
This PU wall sandwich panel is mainly used in refrigeration or refrigeration equipment in food and other industries, such as refrigerators, freezers, cold storage, refrigerated trucks, etc. Polyurethane rigid foam is the most ideal thermal insulation material for refrigeration and refrigeration equipment.
