Introduction to Polyurethane Composite Board

Polyurethane composite board is a high-performance building material consisting of a rigid polyurethane (PUR) or polyisocyanurate (PIR) foam core sandwiched between two facings, typically metal (steel or aluminum), aluminum foil, or fiber-reinforced polymer. This structure provides exceptional thermal insulation, structural rigidity, and fire resistance. The closed-cell foam core offers a thermal conductivity as low as 0.022 W/m·K, making it one of the most efficient insulation materials available. These boards are widely used in cold storage facilities, industrial buildings, clean rooms, and exterior wall cladding. The global demand is driven by energy efficiency regulations, cold chain logistics expansion, and sustainable construction practices. The product is available in various thicknesses from 20 mm to 200 mm, with custom lengths and widths. The facings can be coated with PVDF, polyester, or HDP for enhanced durability and aesthetics. Polyurethane composite boards are also known as sandwich panels, insulated metal panels (IMP), or PIR boards.
