Ok got it. Is there a need to use backing rod and caulk or will just one suffice?

Can you give me some more info on decouplers? At a store over here in Spain that deals with isolation and soundproofing they recommend using this tape in between the steel framing and floor/ceiling (see attachments, it is called "Banda estanca" in spanish). Is this what you mean?

Ok well now you got me there. Doesn't a split unit also ventilate? doesn't it remove old air and supply new? If not then will obviously reconsider.

Thanks Starlight. You're giving me good stuff. Appreciate it.
