Best option for a new builds ceiling

Hi there again, guys my plans r currently at the building planners office getting finalized, i am building a studio closely compared to sonar studios, i need some advice, what would you recommend and would be the cheapest option for the buildings ceiling? i was planning to do a concrete slab but the buliding inspector has told me that if i want to do that it needs to be done by an engineer and this could cost alot? what other options are there and have you guys used? a normal a frame tile ceiling wont probably be as effective in sound isolation as a cement one?? im not asking for advice about adding in a suspended ceiling, this i will do later i just need some advice on building the raw buildings ceiling effectively cost wise and sound isolation wise Another option would be to install a sink roof and gypsym ceiling, i know the sink roof wont be great for sound isolation but if i place rockwool between the sink roof and the gypsym board ceiling it could provide enough sound isolation? what is your take on that? i will also the still ad in another suspended ceiling below the gypsom board ceiling? Thanks in advance

your question is open ended with little detail of what the current room is constructed with. These are the details you should be providing for anyone to give you competent advice. In the Studio Construction main page, you'll find the first two links that are always set at the top of the list. There's one that you should read first and it's actually titled as such and then the reference area has a bunch of relevant info for what you're asking. Don't be hasty with making a decision if you're serious about isolating sound. This type of construction can be easily screwed up if certain details are not paid attention to.

Hi there Preludetojune, and I guess it's a warm welcome back to the forum? I respond in earnest, since my Mum's name was June. When I first learned to talk I called her 'Dune' because I was too young to be able to pronounce June. Dune later became 'Dooney' A name that I called her as readily as 'Mum' always. As for your questions, my best advice at this point would be as follows: http://www.johnlsayers.com/phpBB2/viewtopic.php?t=3231 http://www.johnlsayers.com/phpBB2/viewtopic.php?t=2125 We all need much more info to be able to help you, and the the rules exist (on this site for sure), for a very good reason. :wink: :wink: Good luck with your project, Kind regards, Lou. 8)

You beat me to it Cram by 30 seconds! :wink: :wink: :wink: Dude - Regards! :wink: Lou. 8)

Lemme guess.. a roof made out of sink? :D

The reason i didnt specify materials is because the room has not yet been built, hence my question what would be the best options for roofing, cost and isolation wise? its a straight forward question and im sure you guys dont need all my info to answer it?

No sir...I have no professional idea what a sink type roof is. Maybe if I knew what Country you lived in I could look it up? Is there a picture somewhere that maybe you could point me to?

Not any sort of expert here but the size of the room/building have an impact on what can and can't be done, what are the spans you are dealing with, how high is the building going to be and what do you mean by 'ceiling' if it's not a stupid question. Rod gave some advice to someone about ceilings in a recent post here where he advised building a decent 2 leaf isolator into the roof and then build the inner rooms with drywall to the inner-frame of the room within rooms only. Search for that thread as it may help, only know i read it in the past 2 weeks so it should be somewhere within the first 2 pages, look for thread starting Roof and 3 leaf . Hope this helps, all the best .

yeah dude dont forget to fill in your location....Or you,ll get the dreaded..Please refer to this link here..blah blah... Oh crap.....someone beat me to it. :lol: :lol:

ok, a sink roof is a roof made from tin, where tiles would normally be used, my location is south africa so sink is probably an afrikaans word, hahahah,

I guess. Thermal sink comes to mind, but you guys are sub tropical so maybe not. Sink...to descend to the bottom.
