Product Description

Product Description

PU/PIR Sandwich Panels

PU/PIR sandwich panels, composed of polyurethane (PU) or polyisocyanurate (PIR) foam cores sandwiched between metal or other material facings, are widely used in construction and industrial applications due to their excellent thermal insulation, lightweight structure, and durability.

Product Features:

Cold Storage and Refrigeration: PU/PIR panels are ideal for constructing cold rooms, warehouses, and refrigerated facilities, maintaining low temperatures for food, pharmaceuticals, and perishable goods due to their superior insulation properties.

The core material adopts a new generation of the rigid PU PIR foam composite material system,which effectively blocks heat  conduction, thereby excellent thermal insulation performance

Rational joint design, great thermal insulation effect, and superior mechanical performance

Excellent thermal insulation performance, high economic benefits, reduced air loss and solar radiantheating, thereby lower energy consumption & costs, CO2 emissions, and building energy consumption

Meet various major fire protection standards in the world
Lower volatile organic compound (VOC) emissions, environmentally friendly and sustainable
