📦 Products Description
PUR sandwich panels consist of a core made of polyurethane foam, sandwiched between two outer layers, usually made from sheet metal such as galvanized steel or aluminum. Panel thickness can vary, typically 50mm to 200mm, depending on specific insulation requirements. The polyurethane sandwich panels are engineered to provide good insulation, structural integrity, and versatility, making them ideal for a variety of refrigeration applications.
