Cold Room Panel Thickness & Thermal Insulation Sizing Guide
Engineering guide comparing 60 mm to 200 mm PUR/PIR cold room panel thicknesses, U-values, condensation thresholds, and lifecycle energy savings.
1. The Hidden Electricity Cost and Condensation Risk of Undersized Panels
Using 80 mm panels instead of 120–150 mm in a -18°C freezer causes outer surface temperatures to drop below ambient dew point, creating surface condensation while increasing compressor electricity consumption by 30–40%.
2. PUR vs PIR Core Chemistry and Surface Coating Selection
At 40–42 kg/m³ closed-cell density, PIR provides enhanced fire performance required by industrial insurers, while PVC-laminated or AISI 304 stainless steel facings protect against corrosive food-processing washdowns.

Questions Fréquentes sur l'Ingénierie et la Fourniture
Questions techniques fréquentes sur les portes frigorifiques, le choix de l’épaisseur des panneaux, l’étanchéité et les projets clé en main.
C11 Which cold room panel thickness should be selected for each operating temperature regime?
General engineering guideline: 60–80 mm for +8/+15°C cool storage, 80–100 mm for +2/+8°C chillers, 100 mm for 0/+4°C fresh storage, 120–150 mm for -18/-22°C freezers, 150–180 mm for -25/-30°C deep freeze, and 180–200 mm for -35/-40°C blast freezers.
C12 What is the main difference between PUR and PIR insulated cold room panels?
Both provide high thermal insulation at 40–42 kg/m³ density, while PIR (Polyisocyanurate) features an enhanced isocyanurate ring structure that delivers superior fire resistance, reduced smoke emission, and compliance with industrial property insurance standards.
C13 What is the difference between Cam-Lock modular panels and continuous-line slip-joint panels?
Cam-lock modular panels allow rapid assembly and future disassembly/relocation for walk-in cold rooms. Continuous-line labyrinth slip-joint panels are engineered for tall industrial cold storage buildings and long partition walls up to 13.5 meters.
C14 Why is floor insulation critical in cold rooms and freezer chambers?
Without proper floor insulation in sub-zero rooms, ground moisture freezes and expands (frost heave), cracking the concrete slab. Modular rooms use birch-plywood + stainless steel floor panels, while forklift-rated warehouses use multi-layer high-compressive XPS/PIR below a reinforced concrete slab with underfloor heating or ventilation.
C15 Why are hygienic cove skirtings and rounded internal/external corner profiles (A02) required?
Sharp 90-degree wall-to-floor and wall-to-wall angles trap bacteria and organic residues. HACCP, IFS, and BRCGS food safety audits require coved (rounded radius) PVC/aluminium hygienic profiles for effortless sanitation.
C16 Which cold rooms require a pressure relief valve (A03)?
Rapid air contraction after door closure or defrost cycles creates strong vacuum pressure inside sealed rooms. Heated pressure relief valves are mandatory in all sub-zero freezers and blast rooms to prevent panel implosion and vacuum-locked doors.
