The LQLK-816 cold storage insulation panel is designed for temperature‑controlled environments. With a rigid polyurethane (PIR) core, it offers excellent thermal insulation, high compressive strength, and low thermal conductivity. Suitable for cold rooms, freezers, and other controlled atmosphere facilities.
