replace12" ceiling tile with drywall on dropped
 
I have an 11' x 13' kithen, had 12' ceiling. Somtime 25-30+ years ago
ceiling was dropped to 9' with 2x4's on 24" centers with 1x2 gridwork for the 12" tiles. Can I take down the square tiles and hang drywall on the gridwork?


Thanks.

Maybe. If in doubt of the capability of the grid to hold the additional weight, have it checked by a professional.

If the grid was installed correctly it will hold the drywall. But how would you attach drywall to this without it pushing up. It is normally hung from the ceiling and has no support except it's own weight from being pushed upward.

are you speaking of using drywall and cutting tiles from that or just using the gridwork as a support for the drywall?

If the tiles idea, I see no problem with it. There are tiles made of drywall on the market so I cannot see how you making your own would be any different.

if you are speaking of screwing drywall to the underside of the grid:

there is a system out there that does just this but I believe it is heavier than actual ceiling grid. It must be able to retain the screw without pulling out at the weight of the rock bears down and moves and wiggles through the years.


so, which installation style were you speaking of?

which way do the 2x4 span? if there is no center support to ceiling above I think it will at very least sag

You think? Or are you just guessing? :laughing:

What ceiling tiles are on the market that are made of drywall?

I/m sure you have span charts handy show me why it would not sag

2x4 ceiling joists 24" OC only to L180 even if structural grade will span less then 9'

#2 grade & L360 brings it in under 7' span

I didn't even need a span chart to know it was too far for 2x4's

I would reinforce the support of the 2x4's & use those if level

There are gypsum panels made to drop in suspended ceiling grid. I don't think that is the type of grid the OP is describing though.

it's a vinyl coated and generally used in clean rooms and food prep areas.

#1- Replace with 4x8 or 4x12 sheets of drywall.
#2- they are true 2x4's
#3- I was planning on using 3' screws to go through the 1by and into the 2x4

#4 I thought about a 2x4 or 6 running perpendicular to the 2x4's fastened to true ceiling with drop down supports for mid span of the 2x4's

#5- 2x4's run width 11' not 13
#6- Drywall to run lenth 13'

thanks

Bj,
What you are thinking may work. But if it were me, I would just tear out the old, and frame it with 2 x 6's on 16" centers. You could do that in about the same time as trying to reinforce the present framing. Then you don't need 3" screws and the like. It would be a normal installation. Use the old 2 x 4's for something else, maybe a new workbench or something.

I'd be tempted to run the 2x6 down the middle & put in support (cables ?) to the ceiling above

I'd buy 12' long drywall & cut it to the 11' width of the room

This is one of those things that seeing it in person can make all the difference in what you do
