PU Sandwich PanelPU insulated panel is a composite prefabricated building material. It is made up of a rigid core sandwiched between two metal sheets. The rigid core is made of polyurethane which is known for its excellent heat insulation properties. Polyurethane is the most widely used insulation material for cold-rooms and energy efficient buildings.
PU Sandwich Panels are composed of 3 layers, the external and internal is two dyed Galvanized or Aluminum corrugated plates, and core high density POLYURETAHE foam. Thanks to their properties the panels may be applied in object that require very high fire resistance, PU sandwich panel is the most effective acoustic materials used on construction.
PU sandwich panel with polyurethane foam cores meet the strictest heat insulation requirements, while also complying with the required insulation properties and maintaining a good bearing capacity.
PU sandwich panel has beautiful appearance and good overall effect. It integrates load-bearing, thermal insulation, fire prevention and waterproof, and does not need secondary decoration. It is fast and convenient to install, short construction period, good comprehensive benefit, and has good cost performance advantages. It is a kind of high-efficiency energy-saving building envelope material with wide use and great potential. It is also a new type of energy-saving board advocated and promoted by the Ministry of construction.
Take the 50 mm thick PU sandwich panel for example and the panel can absorb the sound over 30 db/m2.Widely used in the steel structure factory building, activities room, roof, wall, air clean room ceiling and partition.
PU (Polyurethane) = Good Heat Insulation
PU Sandwich Panels with polyuret with polyurethane foam cores meet the strictest heat insulation requirements, while also complying with the required insulation properties and maintaining a good bearing capacity.
PU sandwich Panel advantages1.PU insulation panel has the advantages of uniform bubble hole, high strength, heat insulation, good dimensional stability and low water absorption.
2.PU sandwich panel is nontoxic and tasteless.
3.PU sandwich board has good bending capacity and load-bearing effect, and its shrinkage advantage also makes the installation more convenient.
4.The disadvantage of pu sandwich panel is the high cost, PU sandwich panel is expensive than other insulated panels.
