Key Engineering Advantages for This Sector
Structural Demands & Operational Challenges
Cold storage warehouses and food processing facilities represent the most unforgiving application in structural building physics, where thermal envelope performance directly dictates inventory preservation or catastrophic product spoilage. Unlike conventional industrial envelopes, cold storage envelopes operate across massive temperature differentials (ΔT) of 40°C to 65°C between exterior ambient air and interior chilled chambers. When ambient summer air reaches +35°C while a deep-freeze room operates at -18°C or a blast freezer operates at -40°C, atmospheric moisture exerts tremendous vapor pressure attempting to penetrate the building envelope. Any micro-void, thermal bridge, or fastener penetration causes immediate vapor freeze, ice-lensing within panel joints, structural ice expansion, and continuous refrigeration compressor overload. SerPan Metal delivers a fully coordinated cold storage envelope system incorporating wall, ceiling, floor, and specialized door systems.
Optimized Composite Panel & Sub-Framing Systems
SerPan Metal addresses these challenges through its integrated SP-COLD-WALL, SP-COLD-CEIL, SP-COLD-FLOOR, and SP-COLD-DOOR system. Our cold storage panels incorporate embedded eccentric steel cam-lock mechanisms along tongue-and-groove profiles. During installation, a quarter-turn with a hex key pulls adjoining panels together with over 250 kg of clamping force, compressing dual EPDM factory gaskets for an absolute airtight seal. Insulation thickness is tailored precisely: 80mm for chillers (+4°C), 120mm to 150mm for freezers (-18°C), and 200mm PIR for blast freezers (-40°C). Ceiling panels spanning over 4 meters are suspended using extruded aluminum T-profiles and thermal-break hanger rods. All interior perimeter junctions feature certified food-grade curved PVC coving profiles.
High moment resistance bridging purlin spans up to 2.50m with solar PV readiness.
Airtight tongue-and-groove joint profile with micro-rib surface planarity.
Thermal Envelope, Fire Safety & Energy Performance
Thermal gains and losses through the building envelope represent up to 40% of an industrial facility’s annual operating energy expenditures. SerPan Metal polyisocyanurate (PIR) cores deliver an ultra-low thermal conductivity of λ = 0.022 W/mK, while non-combustible rockwool cores deliver certified fire barriers resisting temperatures above 1000°C for 60 to 120 minutes (REI 60–120).
Weatherproofing & Drainage Engineering
Cold envelope sealing extends beyond the panel joints. Duwalls sit in heavy-duty galvanized or PVC floor floor channels bedded in continuous polyurethane sealant over level concrete curbs. Wall-to-ceiling junctions receive external polyurethane foam seals and internal antibacterial silicone beads. Sub-zero cold room doors feature 220V continuous perimeter heating cables embedded within the frames, preventing rubber gaskets from freezing shut to the frame. Heated two-way pressure relief valves are installed in external walls to equalize internal atmospheric pressure during rapid temperature pull-down cycles, preventing ceiling implosion or wall displacement.
