When to use this system
Suspended refrigeration ceiling made of insPIRe® CH panels is used when:
- Cold chamber interior in an existing facility — existing slab structure is uninsulated, panels are suspended below.
- Hall with internal cold chamber — the chamber does not occupy the full height of the hall, ceiling is insulated at the required chamber height.
- Ripening rooms in dairies / bakeries — suspended ceiling allows easy access to installations above the chamber.
- Cold-storage renovations — ceiling replacement without interrupting chamber operation.
Omega profile characteristics
The Ω profile made of polyester composite is the key to this solution:
- Thermal bridge elimination — polyester has λ ~10× higher than steel, but at the suspension point the thermal bridge is negligible vs. a continuous steel element.
- Ceiling level adjustment — tensioning nut on the Ø10 threaded rod enables precise leveling of the ceiling (±20 mm).
- Stability — galvanised steel M10 nut secures the position.
- Structural capacity — typically 80–120 kg per linear metre of panel (limit depends on panel density and hanger spacing).
Alternative fixings
| Type | Application | Comment |
|---|---|---|
| Ω profile | ceiling with negligible thermal bridging | default choice for freezer rooms |
| T profile | ceiling with higher thermal bridge tolerance | cheaper, lower adjustment precision |
| Direct fixing to structure | when the slab is close (≤ 200 mm clearance) | no bridges, no adjustment |
Installation requirements
- Hanger spacing: typically every 1200–1500 mm (depending on panel thickness and load).
- Panel joints — sealed with PU foam and permanently plastic sealant on the chamber side; PES gasket on the external side.
- Cold-room doors — thermal door frame compatible with the suspension system.
- Ceiling penetrations (evaporators, lighting, sensors) — require dedicated stainless steel sleeves + frost-resistant silicone sealing.
Required flashings and accessories
- OB-17 — covering the panel joint
- OB-36 — closing the panel
- Sandwich panel fasteners (hidden lock for smooth surface on the chamber side)
- PES gasket — polyurethane tape for perimeter sealing
