Also searched as: Heavy Duty Cold Storage Sectional Door
The Cold Storage Sectional Door is engineered for temperature-controlled environments — cold rooms, freezer warehouses, food-processing chillers and pharmaceutical storage where thermal performance and airtight sealing are critical to maintaining the cold chain. RAX builds cold-storage sectional doors with 50 mm (or thicker) PU foam panels, enhanced perimeter sealing and thermal-break track details that minimize heat transfer at the door frame.
For industry context, cold-storage sectional doors typically use 50–100 mm PU panels (industry estimate), compared to the 40–42 mm panels standard in general industrial use (Hörmann EPU/LPU: 42 mm; CN-export: 40 mm at 46 kg/m³, ecer.com). RAX’s marketing target of U-value 0.33 W/m²K thermal performance applies to the insulated panel build and is pending RAX’s own EN-tested report. Perimeter air sealing is designed to the EN 12207 air-permeability framework. RAX tests door systems from −30°C cold storage to +50°C desert conditions (brand capability).

Specify your cold-room operating temperature (e.g. −25°C freezer, +2°C chiller) and ambient-side conditions. This determines panel thickness, seal type and whether a heated frame is needed to prevent ice build-up.
Cold-storage doors typically use 50–100 mm PU panels (vs. 40 mm for general industrial). Thicker panels reduce heat transfer and prevent condensation on the warm-side face. RAX advises on optimal thickness for your temperature differential.
Airtight perimeter sealing is critical for energy efficiency. Specify EN 12207 air-permeability class. For freezer applications, a heated frame prevents seal freezing. Bottom seal: flexible EPDM with compression gasket.
Cold-storage doors should open/close rapidly to minimize cold-air loss. Specify a high-speed operator (VFD-controlled) with radar or pull-cord activation. RAX’s full-category manufacturing includes high-speed operators.
RAX supports full private-label production of the Cold Storage Sectional Door: custom RAL panel colors, operator matching, packaging printing and installation-manual translation (EN/ES/FR/AR/RU). Start with an OEM sample and scale to container-load branded production. Custom molds, Tooling records are archived for up to 5 years — no extra tooling fee on repeat orders, all under strict NDA.
CE marking basis. Includes thermal resistance (U-value) and air permeability as declared characteristics — both critical for cold-storage compliance.
Air permeability classification framework. Cold-storage doors target low leakage class to minimize energy loss and maintain temperature stability.
Mechanical and power-operated safety. Cold environments affect material brittleness — components must maintain safety performance at operating temperature.
Cold-storage sectional doors typically use 50–100 mm PU foam panels (industry estimate), compared to 40–42 mm for general industrial doors. The exact thickness depends on your temperature differential and energy-code requirements. RAX advises on the optimal build.
Options include: heated frame profiles (prevent seal freezing), thermal-break track details (reduce cold bridging), and high-speed operation (minimize exposure time). Specify your operating temperature and we design the appropriate anti-ice package.
RAX’s marketing target is 0.33 W/m²K (pending our own EN test report). For context, a CN-export industrial door lists 0.38 W/m²K (ecer.com) and Hörmann achieves 0.5–1.3 W/m²K depending on configuration. Thicker cold-storage panels (50–100 mm) achieve lower U-values than standard 40 mm panels.
