Containment Roof Panels: Fixed Tops and Drop-Away Fire Panels
The roof is the part of a containment boundary that must do two opposite jobs: hold cold supply air inside the aisle, and surrender instantly when the sprinkler above needs the volume. RackForge resolves that with one 600 × 1200 mm module in three panel types — powder-coated steel where cable drops pass, tempered glass where you want eyes on the aisle, and drop-away fire panels whose fusible elements let go below 72°C and swing the flap 90° clear of the spray. Everything lays into support rails without site drilling, and the FA linkage test record ships with every order, serial-matched to the panels it describes. Fixed tops carry the LED strips and camera mounts; drop-away panels carry the one moving part in the whole boundary.

Six items on every roof delivery
Roof hardware is fire-critical, so the list is short and documented: every panel is either standing hardware or a tested safety device, and the paperwork travels inside the crate with the panels it describes. If an item below is missing from a delivery, treat it as a punch-list failure, not an option you can add later.
Fixed steel roof panels — powder-coated 600 × 1200 mm tops that carry the aisle's standing surface and the cable-drop cutouts.
600 × 1200 mmGlass roof panels — tempered, frame-mounted, for daylight-path visibility and camera coverage into the aisle.
temperedDrop-away fire panels — fusible element releases below 72°C; the flap rotates 90° down and clears the sprinkler envelope.

The one panel in the aisle designed to fail
A sealed ceiling and a sprinkler head want contradictory things, and the drop-away panel is the mechanical truce between them. Under normal conditions a fusible element holds the flap level, closing the boundary the same as any fixed panel. When the air around it passes roughly 72°C, the element lets go and the flap rotates 90° down — the ceiling opens before the sprinkler needs it, and water reaches the aisle face without a barrier in the way.
- Sprinkler geometry: released panels leave at least 70% of the area below the head clear, aligned to NFPA 13 expectations for obstructions under sprinklers.
- Two triggers: thermal release is standard; electric release on smoke-detector signal is optional for buildings where the detector leads the heat.
- Proof, not adjectives: the FA linkage test record logs release function per batch — the same document discipline as our load-test and pressure records.
- Closes on the same module: panels land on the 600 mm grid that the glass end doors and rack tops already follow, so one layout drawing covers the whole boundary.
Roof panel datasheet
One module, three panel types, one set of interfaces. Mixed steel, glass and drop-away panels share a single aisle run without adapters, and panel counts come from the row drawing — send the layout and we return the placement plan with the quotation.
