PU / PIR Cold Room Panels
Cam-Lock and Plug-in sandwich panels with polyurethane core and color-coated steel. 15-20 year lifetime.
- 50-200mm insulated sandwich panels
What The PU / PIR Cold Room Panels Does
Howcool PU / PIR Cold Room Insulation Panels are the structural skin of any modern cold storage facility. Cores are high-density polyurethane (PU) or fire-retardant polyisocyanurate (PIR) foam, foamed between two pre-painted galvanized steel skins in a continuous production line. The result is a monolithic sandwich panel with excellent thermal performance (λ ≤ 0.022 W/m·K) and long-term dimensional stability.
Standard panel thicknesses: 75/100/125/150/200mm. Widths: 950/1000/1150/1200mm. Lengths: up to 12m. Cam-lock connections allow quick on-site assembly without bolts or welding. Floor, wall and ceiling panels are supplied as a coordinated system with custom corner pieces, T-joints, and matching cold-storage doors.
Our cold room panels are crafted using a blend of polyisocyanate and polyether or polyester polyol, resulting in a high-performance product. Known for superior heat conductivity, temperature preservation, compressive and tensile strength. Available: 100-120mm for cold storage, 150-200mm for freezer, 200-250mm for quick-freezer.

Why Buyers Choose This Model
PU or PIR Foam Core
PU density 40-42 kg/m³ for walk-ins. PIR fire-retardant Class B1 required for food processing and pharmaceutical cold storage.
Pre-Painted Steel Skin
0.4/0.5mm galvanized steel with polyester or food-grade PVC coating. Stainless-steel option for pharma and hygiene-critical applications.
Cam-Lock Assembly
Hidden cam-lock joints foamed into both edges. On-site installation is 3-5× faster than bolted panels. No thermal bridging.
Certified Performance
Each batch tested for density, closed-cell ratio and thermal conductivity. Typical λ = 0.022 W/m·K after ageing.
Cold Room Panels Failure Modes
Heat ingress that never stops
Polyurethane panels with low thermal conductivity in thicknesses from 50 to 200 mm; on our Jeddah design, 150 mm cut summer heat ingress by over 40% against 100 mm.
Fire compliance
PIR fire-rated and rockwool fire-wall panels for sites where the insulation core has to meet building fire codes.
Frost heave under the slab
Embossed aluminium floor panels and insulated floor build-ups with anti-frost-heave heating for freezer rooms.
