PUF Sandwich Panels are a type of insulated panel made by sandwiching a layer of Polyurethane foam (PUF) insulation between two layers of rigid facings such as steel, aluminum, or fiber-reinforced plastic (FRP). These panels are used for various applications such as building walls, roofs, cold storage, and walk-in freezers. PUF sandwich panels provide excellent thermal insulation properties and can help to reduce energy consumption and costs. The high insulation properties are due to the PUF core which has a low thermal conductivity and a high R-value, which means it is resistant to heat flow.
