Puf panels, also known as polyurethane foam panels, are widely used for their excellent thermal insulation properties. These panels provide effective insulation to maintain desired temperatures inside the cold room and prevent heat transfer from the external environment.

Puf panels are constructed using rigid polyurethane foam as the core material sandwiched between two layers of colored steel sheet or other suitable materials. This construction gives the panels high strength-to-weight ratio and durability, making them suitable for cold room applications.

Overall, Puf panels are an ideal choice for constructing efficient and well-insulated cold rooms, providing the necessary thermal resistance and energy-saving capabilities.
