Gypsum and False Ceilings in the UAE: What to Know Before You Install

False ceilings hide the ducting and wiring and let you shape lighting. Done badly, they crack along the joints within a year.

Quick Summary

  • False ceilings hide AC ducts and wiring and let you build in lighting.
  • They crack when the joints move or the taping and skim are done poorly.
  • Good installation is about proper framing and jointing, not just the board.
  • Standard gypsum board suits most work, GRG suits decorative curves.

A false ceiling does two quiet jobs. It hides the ducting and wiring above it, and it lets you shape a room and its lighting. Done well, you never think about it. Done badly, it cracks along the joint lines within a year and you think about it every time you look up.

Here's what decides which one you get with gypsum and ceiling work.

Why false ceilings crack

Cracks almost always appear along the joints between boards. The causes are movement, poor jointing tape and compound, or fixing to a structure that flexes. Good installation means proper framing, taping the joints correctly and a skim coat that doesn't telegraph the seams underneath. It's unglamorous work, and it's the difference between a ceiling that lasts and one that cracks.

What a false ceiling is actually good for

  • Hiding AC ducts and pipework above the room
  • Building in recessed LED and cove lighting
  • Improving acoustics in offices and living spaces
  • Shaping a room with drops, coffers and curves

Gypsum board or GRG

For most ceilings and partitions, standard gypsum board is the right choice. For decorative curves, domes and moulded detail, GRG or cast work gives shapes board can't. It sits above your AC ducting, so the two get planned together during a fit-out.

Frequently Asked Questions

Why has my false ceiling cracked?

Almost always at the joints, caused by movement or poor taping and jointing. A proper repair means fixing the joint correctly rather than filling the crack, which otherwise reappears.

Can you hide AC ducts and wiring in a false ceiling?

Yes, that's one of the main reasons to install one. We plan the ceiling around the ducting, pipework and lighting so everything is concealed and still accessible for servicing.

What's the difference between gypsum board and GRG?

Gypsum board suits flat ceilings and partitions. GRG (glass-reinforced gypsum) is used for decorative, moulded and curved shapes that flat board can't form.
