ceiling panel solution needed

[LegacyGT]

In the granny flat we are restoring there is a floating ceiling installed with panels 1220mm x 915mm.

odd size!?

went searching for any material to suit...

they all come in 1200 x 900 - the standard size.

what shall i do?

it also needs to be strong enuff to support down lights and insulation.

The old 4ft x 3ft sixing that just isn't made anymore trick. D'oh

Try salvage yards. Alternatively call around some of the smaller ceiling manufacturers (Bradys) as some of them are still making old panels. They had to replace a few at the old school i am at and I can't remember who it was who had them but they could get them, bit of a wait though. I would guess that you would pay a premium for them, might be cheaper to replace the whole lot to current spec.

ahhhh the old 4ft by 3ft

i was wondering why such odd dimensions.

thanks a plenty.

is there any other way around it.

last resort would be to replace it with the new dimensions 1200mm x 600mm.

The ceiling is not that difficult to replace. Old ceiling pannels are getting harder and harder to get.

The 915mm size has got me I have never come across that size ceiling tile before standard size would have been 610mm x 1220mm.

You could easily cut your own pannels out of 1350 wide ceiling plaster board. Just cut the rebates off each side to give you the pannel length. Pre paint them and install.

This is not a bad fix for a small area. If the pannel is 915mm wide then you would need to stiffen the plaster board. You can simple get some 2x1 pine and cut it exactly to the width of the pannel and glue them to the back. This will give you the strength. No need to do this if they are in fact 610mm, just use ceiling board.

Yeah it aint that bad. just take me a little longer than I anticipated.

I have thought about using 1200mm x 900mm mdf, and a bit of "2x1" pine and cut it so it overhangs the edge at the sides. But then the panel will drop down a bit and wont be flush with the frame.

What do you reckon?

Your right about stiffening the board - thats why im replacing the old stuff - its sagging.

Thanks guys.

[rod@plasterbrok]

If you use mdf you won't need the battens to over hang.

I presume these pannels are sitting in a tee section?

Cheers

The MDF is sourced was only about 5mm thick so it would sag.

I have decided to redo the grid framing system. coz the wife reckons its better. hah!

I like the idea of 10mm plasterboard. Cheap, can be cut easy, light, and with a batten liquid nails or stud adhesived to it, will be quite rigid. That is what I would do.

[LegacyGT]

Yeah the 10mm plasterboard is cheap but the length is 1220mm whereas the plasterboard comes 1200mm wide.

have also found another alternative in replacing the wholegrid system called coruline.

will cost as much as replacing the current setup to 1220x600mm grids.
