The 50mm PU/PIR Cold Room Panel is the lightweight specialist of the cold room panel family: thin enough to minimize space loss, efficient enough to hold chill temperatures reliably, and economical enough for rooms where deep-freeze thickness would be wasted engineering. With a polyurethane or polyisocyanurate core conducting heat at just 0.022 W/mK, the panel maintains 0°C to +10°C storage environments – chilled foods, beverages, dairy, produce and pharmaceuticals – while preserving interior floor area in buildings where every centimeter of storage volume is revenue.
The 50mm panel serves positive-temperature duty across the cold chain: walk-in chillers in restaurants, hotels and supermarkets; beverage and dairy storage rooms; fruit and vegetable holding rooms; chocolate and confectionery conditioning spaces; pharmaceutical chill storage; and flower coolers. It is equally effective as insulated partitions separating chill zones from ambient halls, and as retrofit linings that convert ordinary rooms into temperature-controlled storage without sacrificing floor area. Where rooms must be built inside leased retail or warehouse spaces, the slim profile is often the deciding factor.
Insulation thickness should follow the temperature difference the wall must resist – and in chill rooms that difference is modest. A room at +2°C in a 30°C ambient faces a 28-degree differential; a freezer at -25°C faces nearly 55. Specifying freezer-grade 150mm walls for a chiller buys almost nothing operationally while consuming floor space and budget. The 50mm panel is engineered for exactly this duty: its 0.022 W/mK core keeps heat gain low enough that standard refrigeration packages hold temperature comfortably, while the slim profile preserves storage volume. The engineering check we perform for every project confirms the thickness against room temperature, ambient conditions and door traffic – so the result is neither over-built nor under-insulated, but correctly engineered. For rooms with mixed temperature zones, 50mm partitions combine seamlessly with thicker freezer walls in the same panel family.
Continuous lamination holds core density at 40 kg/m³ and bonding quality across the slim profile; panels are cut to length, inspected and packed by position. Arteco prepares room layouts with joint and junction details, coordinates panels with doors and refrigeration, and supports installation so chill rooms reach stable temperature quickly and hold it efficiently.
Yes, for rooms at 0°C to +10°C in typical climates. We verify against your ambient conditions and door usage; high-temperature or high-traffic sites may move to 75mm for margin.
No – freezer duty at -18°C and below requires 150–200mm thickness to control heat gain and prevent frost problems. The 50mm panel is engineered for chill and partition duty.
Each wall line saves 100mm of build-up per side. In a 5m × 5m walk-in, moving from 150mm to 50mm walls recovers roughly one square meter of storage floor – significant in retail back-of-house rooms.
Yes. Stainless facings suit washdown environments; color-coated and galvanized facings cover standard chill storage. Facing choice is confirmed per room during order review.
Absolutely – partition duty between temperature zones is one of the panel’s strongest uses, providing thermal separation and acoustic damping without adding structure.
Slim-wall construction earns its value most clearly in retrofit projects, where every centimeter of preserved floor area becomes storage capacity. When converting an existing room into chilled storage, wall build-up directly reduces usable volume – a 150mm freezer wall in a small room consumes floor space that could hold product. The 50mm panel minimizes this loss while still holding chill temperatures reliably, which is why it dominates conversions of back rooms, leased spaces and existing structures. Planning the conversion around slim walls extends to doors and equipment too: door frames sit flush in thinner reveals, and evaporator placement can exploit ceiling space without encroaching on storage height. For operators paying rent per square meter or measuring capacity in pallet positions, the volume preserved by slim construction often pays for the room itself.
Each wall line saves 100mm of build-up versus 150mm panels – in a 4m × 4m room, roughly 0.8 m² of floor area. We calculate the exact volume benefit for your room dimensions during design.
