PU/PIR panels, cold storage doors and matching accessories for stores holding produce, seafood and fresh food from above zero down to -45°C.
Solution overview
A cold store makes the toughest demands of any envelope: one thermal bridge or one open joint pushes the electricity bill up for the store's whole life, quite apart from the condensation that can spoil the goods.
Phu Son supplies the complete store envelope: solid-core PU/PIR panels, a tight interlocking joint, purpose-made sliding and hinged doors, and a matching set of trims and corner pieces. Every panel is made to the chamber's exact dimensions, which keeps on-site joints to a minimum.
Technical specifications
All figures below are taken from the Phu Son Group 2026 product catalogue. The final configuration depends on each project's design documents.
Every door uses 40 kg/m³ PU foam and comes as a single or double leaf, wall-mounted.
| Door type | Temperature range | Leaf thickness | Dimensions | Heating element |
|---|---|---|---|---|
| Sliding door | cold store down to -20°C | 100 mm | 600×600 - 3,500×5,000 mm | heating element fitted |
| Sliding door | deep-freeze and freezer store -20°C to -45°C | 125 - 150 mm | 600×600 - 3,500×5,000 mm | heating element fitted |
| Hinged door | above-zero store over +7°C | 50 mm | 600×600 - 1,500×2,500 mm | no heating element |
| Hinged door | deep-freeze and freezer store -20°C to -45°C | 75 mm | 600×600 - 1,500×2,500 mm | no heating element |
The WCB line is for produce (vegetables, roots and fruit); the WFB line is for fresh food (fish, meat and seafood).
