In the refrigeration industry, maintaining optimal temperatures and insulation is essential to preserve perishable goods. One of the most effective materials used in building cold storage facilities is PUR/PU - polyurethane cam lock sandwich panels. These panels are designed to provide superior thermal insulation, structural integrity, and ease of installation, making them ideal for a variety of cold storage applications. Polyurethane Cam Lock Sandwich Panels are widely used in a variety of cold storage applications，and the PUR/PU (polyurethane) cam lock sandwich panels are an excellent choice for cold storage insulation due to their high heat resistance, lightness, moisture resistance and durability.
