Cold storage facilities, where temperature fluctuations can cause condensation, rely on polymer waterproof membranes to maintain insulation efficiency. Weifang Luyang’s XPS-backed bitumen membranes, combining waterproofing with thermal insulation, are ideal for such environments. A cold storage warehouse in Russia’s Siberia region adopted our membranes to seal its concrete floors, preventing frost heave and moisture damage to stored goods. The membranes’ closed-cell structure minimized heat transfer, reducing energy consumption by 15%. Our automated production lines ensured rapid delivery of custom-sized sheets to the remote site.
