Cold storage warehouses and frozen food facilities operate at temperatures as low as -30°C, creating a unique challenge for fire safety systems. Most traditional fire-rated wall materials lose their structural strength and fire resistance at extremely low temperatures, making them unreliable for freezer applications. ALC wall panels are the only fire-rated partition material that maintains full structural integrity and fire performance even in continuous sub-zero environments.

Traditional gypsum board becomes brittle and cracks easily at temperatures below 0°C, completely losing its fire resistance within a few years of operation in a freezer. Composite insulation panels with polyurethane cores are highly flammable, and can release massive amounts of toxic smoke when ignited. ALC panels, by contrast, are made of inorganic aerated concrete that does not change its properties even at -30°C. They do not become brittle, do not crack, and maintain their full 3+ hour fire resistance rating for decades of continuous low-temperature use.

ALC panels also combine fire safety with excellent thermal insulation performance, which helps reduce the energy cost of running the cold storage facility. Their low thermal conductivity means less cold air escapes through the partition walls, lowering the load on the refrigeration system and cutting monthly electricity bills. Unlike flammable foam insulation panels that create hidden fire risks, ALC’s insulation performance comes from non-combustible trapped air bubbles, so there is zero trade-off between energy efficiency and fire safety. This makes ALC panels a perfect dual-function solution that improves both fire safety and operational efficiency for cold storage operators.
