What is PU Foam Board and how is it manufactured?

PU (Polyurethane) Foam Board is a rigid insulation material composed of closed-cell polyurethane foam sandwiched between facers like aluminum foil, glass-fiber mat, or paper. It’s manufactured through a continuous lamination process where liquid polyurethane components (polyol and isocyanate) are mixed, foamed, and cured between the facers under controlled temperature and pressure. This process creates a homogeneous board with exceptional thermal properties and structural integrity, making it one of the most efficient insulation products available.
