False Ceilings & Partitions
False ceilings and partitions are the grid or gypsum ceilings and the drywall, demountable or glass walls of an office fit-out. Grid ceilings keep the plenum accessible while gypsum gives a seamless surface, and partitions around rooms needing privacy run to the slab, since walls stopping at the ceiling leak sound through the shared plenum.

What we deliver
Grid and gypsum ceilings, drywall, demountable and glass partitions — installed as part of the fit-out and coordinated with everything that runs above and through them.
Ceilings and partitions look like the simplest package on a fit-out. They are actually the package that touches every other trade: sprinklers, diffusers, lighting, cable tray, smoke detection and speakers all land in or pass through them, and every cabin wall interrupts all of it.
Scope of works
| Stage | What we deliver |
|---|---|
| Coordination | Reflected ceiling plan agreed against MEP and sprinkler layouts |
| Setting out | Grid alignment to the module, partitions to the layout |
| Framing | GI framework, hangers, studs and track |
| Boarding | Grid tiles, gypsum board, acoustic or fire-rated where required |
| Services | Cut-outs for diffusers, lights, detectors, speakers, sprinklers |
| Finishing | Jointing, taping, skimming, paint |
| Compartmentation | Partitions to slab and plenum sealing where required |
Ceiling types
| Type | Best for | Trade-off |
|---|---|---|
| Mineral fibre grid | General open plan | Accessible; standard appearance |
| Metal grid | Corridors, wet areas | Durable; higher cost |
| Gypsum | Reception, curves, feature zones | Seamless; access needs traps |
| Acoustic baffles / rafts | Open plan noise control | Effective; requires coordination |
| Exposed services | Informal and creative offices | No ceiling cost; MEP must look intentional |
Where projects go wrong
- Reflected ceiling plan not coordinated before boarding. Then diffusers, sprinklers and lights fight for the same tile and the ceiling looks accidental.
- Meeting room partitions stopped at the ceiling. Sound travels over the wall through the shared plenum. The room is visually private and acoustically not.
- Compartmentation broken by the fit-out. Partitions crossing a fire compartment line must maintain the rating, including at penetrations.
- Access ignored. A gypsum ceiling over a floor full of VAV boxes and valves means cutting it open the first time anything needs service.
- Grid module set out from the wrong edge. Cut tiles at the visible end rather than the concealed one — a small decision that reads as sloppy for the life of the fit-out.
Why Hagerstone
15 carpenters in-house within a team that also delivers the MEP the ceiling has to accommodate — so the reflected ceiling plan is coordinated internally, not negotiated between two contractors on site.
79+ quality checkpoints under ISO 9001 / 14001 / 45001, on a 60-day delivery model with a 5-year warranty.
