Glostar cold room panels are engineered for high-performance thermal insulation systems used in cold storage, pharmaceutical warehouses, food processing plants, and logistics facilities. Our PU / PIR insulated panels ensure stable temperature control, airtight sealing, and long-term energy efficiency.

A cold room panel is a prefabricated insulated sandwich panel designed to construct temperature-controlled environments. It consists of two metal facings (steel or aluminum) and a rigid insulation core such as PU or PIR foam, forming walls, ceilings, and partitions for cold storage systems.
Glosta operates a fully automated production line for cold storage panels, featuring world-class 7-component foaming equipment imported from Italy. This system enables real-time, one-step mixing and automatic adjustment based on temperature, resulting in distinctive materials that offer high strength, energy efficiency, eco-friendliness, sound insulation, and fire resistance. The production line boasts high efficiency, excellent synchronization across units, and a high degree of automation, achieving an annual output of 1 million square meters. The resulting polyurethane energy-saving insulation panels are characterized by their attractive appearance, ease of installation, superior thermal insulation, and fire-resistant properties.


Cold room performance depends not only on insulation thickness, but also on joint sealing, vapor barrier control, and thermal bridging prevention. Poor panel design can lead to condensation, energy loss, and temperature instability, especially in high-humidity environments.
