Alternative sparse paneling

[gadu^]

Today, we have a pine ceiling in the living room that we plan to remove to insulate the intermediate floor for various reasons. The pine ceiling is tongue-and-groove, perhaps 70mm wide "planks" and ~10mm thick. The intermediate floor joists are spaced at CC60. We plan to put up a drywall ceiling, and as I understand it, you should use furring strips 28x70 with CC30 to attach the ceiling drywall.

But since I have these "pine planks" left over when you take them down, would it work to put up these planks at CC30 as furring strips after insulating, or are they way too weak?

Every centimeter you can save in ceiling height is better...

none?

Sure, be patient.
I'm sure 10 mm will be way too thin. You'll regret it if you put them up as spaced paneling.

Hijacking the thread a bit: is it possible to install 12mm plyfa directly on (under) rafters cc 1200 and then gypsum, i.e. skip the furring...

/F

... I'm afraid it might get droopy with that variant as well.

Sorry for my impatience...
Suspected they would be too weak... but 28mm glespanel and then 13mm plasterboard feels a bit too much in a room that doesn't have particularly high ceilings today. But maybe that's something you have to live with... :S

Thanks Immobil

...or you might have to duck. And high heels, you can forget.

Hehe, after all, it's 237cm in ceiling height but it will be noticeable if you lower it by 3-4cm... I think anyway....

Are there no steel studs of any kind that replace gles?

Technically, they should be able to have a slightly lower profile, maybe about one cm lower.

There are, but according to the pictures here, they seem to be about as thick as gles...

You can always put 45x45 on 300cc between the joists. Then it doesn't add to the height. But it is quite a bit more work. I will do it myself in the basement where the ceiling height is now 1.78m.

MaZtoR, actually thought about that too... but as you say it's more work. The living room is a bit more than 5m deep and probably 10 beams wide and it would probably have been... hmmm 166 joists with CC30?

Sounds like a lot, might have spent too much time in the sun so I'm calculating wrong...

Another thought I have about this is to achieve good sound insulation between the floors. If one were to put drywall on the inside of the sparse panel and then drywall on the sparse panel. Meaning that you put up some spars and insert a 600mm wide drywall sheet that rests on the spars, and finally the drywall as usual when you've put up the remaining sparse. Would this help with the sound between the floors?
