Namely, the concave and convex slot board. After the joint of the male and female grooves with a standard width of 1.12m, fixed with rivets, the middle of the joint has a filling port, which needs to be filled with polyisocyanurate materials for foam filling, suitable for cold storage with high requirements of cold preservation.
Our Pir (Polyisocyanurate) Panel are the ultimate solution for high-performance cold storage insulation, offering superior thermal efficiency, fire resistance, and structural integrity. Designed for walk-in cold rooms, refrigerated warehouses, food processing facilities, and industrial freezers, these panels ensure maximum energy savings, durability, and compliance with international safety standards.
