Hi,


here is the link : http://membres.lycos.fr/tenkas/ceiling.GIF

Let me try direct image:



hehe hope it works

here is a very quick drawing (paint) I did to show you the basic principe of how I will do my ceiling.

I am in the basement so I need good ceiling isolation.

I am on tight budget also hehe

So here it is: I will but fiberglass between the wood studs (if thats how you call them, they support the upper floor) and I will directly mount on the studs SONOPAN (acoustic panel for isolation, weights 30 pounts per sheet). I will the put metal RC on the SONOPAN and the I will put one layer of 5/8 gypsum. Is that good?

Is it better to take some fiberbergalss out to make let say... half space fiberglass half space air? Is it better to put the SONOPAN directly on studs or would it be better to but the RC directly on the studs and then put SONOPAN on RC and then gypse on sonopan?

I have read a lot but I have never seen an answer to this specific question... I hope you guys can help me out

Also, I am building a wall, I have the same question, is it better to put some fiberglass and to let some air space? and is it better in a wall to do
STUDS - SONOPAN - RC - GYPSUM or STUDS - RC - SONOPAN - GYPSUM.

It's also a double wall, which side of the wall should have RC and which side soulds have rc?

Thx a LOTTTTtttt!

Steve answered this in another post. the rc should be attached to the studs then you attach the sono board and gypsum

Bryan is right Tenkas - your way will create what we call a triple leaf (i.e. layer, airgap, layer, airgap, layer) whereas what you want is a double leaf - layer airgap layer. - so you can go layer - airgap - layer layer.
In your case the first layer is the upper floor - then RC - layer, layer.

BYW - the wood is called "floor joists".

cheers
