Insulated sandwich panels consist of two outer layers and an insulating core, combining strength with thermal efficiency. Common materials for the outer layers include metal or concrete, while the core is typically made of polyurethane or polystyrene foam.

Cold Storage Doors 101: Sliding, Swinging & Lifting — What Works Best?

PIR (Polyisocyanurate) and PU (Polyurethane) panels are both widely used in the cold storage industry. They are essential for maintaining low temperatures and improving energy efficiency. While both materials provide thermal insulation, their chemical properties differ significantly, leading to various applications and performance characteristics.

Is your cold room door proving to be an energy efficiency nightmare? Many users of pu sandwich panels experience frustrating energy leaks that lead to inflated electricity bills. These leaks can stem from improper sealing, inadequate insulation, or simply wear and tear over time. Understanding the root causes is essential for maintaining optimal temperatures and controlling costs. In this

PIR panels have better fire resistance due to the additional isocyanurate rings, making them more suitable for areas where the risk of fire is higher. PUR panels, on the other hand, have greater flexibility, which can be an advantage in applications where the material needs to conform to irregular shapes.
