PUR (Polyurethane Foam) is sandwiched between two metal or Aluzinc facings and is increasingly successful in meeting the requirements of cold-room construction. The Polyurethane Foam (PU / PUF / PUR) core meets the good heat insulation requirements, while also complying with the required insulation properties and maintaining a good bearing capacity. Apart from the thermal resistance/ insulation, sandwich panels offer a wide range of desirable properties, because of which increasing demand for these panels is seen. Some of these properties include: Impact resistance and stability. Lightweight and space-saving. Low maintenance and long life Speedy delivery because manufactured on a continuous line Long length and wide spans (rapid and simple erection) Environmentally friendly (CFC and HCFC free) Two types of these PUF panels are available for cold storage construction. 1) Continuous Panels with Tongue and Groove joint 2) CAM LOCK panels The thickness of the panel is decided depending upon the temperature to be maintained in a cold room. The price Of the panel also differs from thickness to thickness.
