100mm 42 Kg / m³ Cold Storage Insulation Panel Color Steel PU Lock Panel
What is PU Sandwich Panel ?
Composed of 2 layers PPGI steel sheet , or aluminum sheet , and core polyurethane foam insulation material .
Sandwich Panel System is suitable for the various roofs and walls referring to the large size factory buildings , workshop , warehouse , exhibition halls , gymnasiums , freezing stores , etc .
Muti - Choices :
According to different usage of insulated panels , PU Sandwich Panel can be divided into three types : Wall panel , Roof panel , Cold Store Sandwich Panel . Widely used in industrial and commercial buildings , Cold Storages , Clean Rooms , warehouses and prefab buildings
Super Insulation :
Low thermal conductivity of PU sandwich panels with excellent thermal insulation properties , can greatly reduce the thickness of periphery of the building structure , which effectively increasing the interior area of the building and save energy and costs .
Super Flame Retardation :
The coefficient of thermal conductivity is 0.023w / ( m • k ) , which ensures better thermal insulation efficiency . In practice , this effectively keeps the building absorbing heat and brings enormous economic benefits .
