How to Choose Cold Room Panels
Refrigerated sandwich panels form the walls of walk-in coolers, freezers and cold storage rooms. These are the specifications that matter when you compare cold room panels, all from our technical sheet:
| Thickness | 1.6, 2, 2.4, 3.1, 3.9, 4.7 and 6 in (40, 50, 60, 80, 100, 120 and 150 mm) |
|---|---|
| Width / length | 39.4 in (1000 mm) wide; lengths up to 39 ft (11,900 mm) |
| Core | Polyisocyanurate (PIR), density 2.3 pcf (40 kg/m³) |
| Faces | G90 galvanized or AZ50 aluminum-zinc coated steel, 0.020 / 0.024 / 0.028 in (0.5 / 0.6 / 0.7 mm) |
| Coatings | Polyester 25 µm (1 mil) or PVDF 25 / 35 µm |
| Joint | Tongue-and-groove |
| Fire test | ASTM E84: flame spread index 20, smoke developed index 300 |
Thickness by temperature: coolers use thinner panels and freezers thicker ones; the right choice also depends on room size and climate, so we recommend the thickness for each project. Finish: polyester is the standard coating; PVDF offers more resistance in demanding environments.
FAQs
What panel thickness do I need for a walk-in freezer?
Freezer rooms need thicker panels than coolers. Tell us the target temperature and room size, and we will recommend a thickness from our 40–150 mm (1.6–6 in) range.
What is the core of your cold room panels?
Polyisocyanurate (PIR) with a density of 2.3 pcf (40 kg/m³), between steel faces with polyester or PVDF coatings.
How long can the panels be?
Panels are 39.4 in (1000 mm) wide and can be supplied in lengths up to 39 ft (11,900 mm).
Do you sell panels separately for an extension or repair?
Yes. You can order insulated panels on their own for a new room, an extension or a replacement. Send us the dimensions and thickness you need.

Walk-in cooler panels and freezer panels
The same PIR sandwich panel is used as walk-in cooler panels and as freezer panels: only the thickness changes, from thinner panels for coolers to thicker panels for freezers within our 40–150 mm range. Insulated cold storage panels can be ordered on their own for a new room, an extension or a repair, together with matching walk-in cooler and freezer doors.
