Polyurethane Panel

Polyurethane Sandwich Panels, often known as PU Panels, are structures consisting of polyurethane foam sandwiched between two side skins made of a different material, such as metal. Thermal insulation is provided by foam in between, Polyurethane panels or Polyurethane sandwich panel is made up of two metal sheets and a rigid core in between. This rigid core has polyurethane material known for its thermal insulation properties. Polyurethane Foam PUF Panels are insulation panels made of metal sheets with polyurethane foam sandwiched in between., A sandwich panel can be defined as a three-layer construction, i.e., two thin facesheets (skin) and a thick core (Marshall, 1998).
