inside out ceiling, with regular walls.

How dare I post twice in an hour. How do you go about hanging drywall if my ceiling will be 'inside-out', but the walls will be regular? Would the drywall at the top of the walls all have to be notched the depth of the joists, and then caulked around it? Is that gonna reduce the integrity of the wall? I just realized I would run into this problem, as my plans were ALMOST done. i think. :(

Ha funny thing that. I was sitting in my half built control room last night (as you do) staring up at my ROOF, soon to be ceiling thinking......That it would be so much easier to do a standard ceiling with clouds rather than attempting an inside-out one. ( I have inside-out walls ) And probably much cheaper! But you will either need to pre-plan that your drywall will over hang the height of the walls by 140mm (height of joist) and somehow make a very good seal once you lay the ceiling drywall on top. Assuming your have plenty of crawl space above your ceiling height for a person and drill. What other guys have done is, simply put blocking in-between each joist (joist off cuts) sealing around them. This also helps with keeping the joist plum and if your handy with the nail gun you might not need brackets. Which will save a few $$$ John’s suggestion is to attach ceiling joist as normal, then build light weight frames that insert in between each rafter. Insulation in the frame cloth stapled over top. My concern wit this is the extra timber for the frames and the not so neat finish that a drooping cloth ceiling has. As I’m a solo builder, a dry wall lifter and standard ceiling will be heaps easier for me.

All good stuff! Hmmmmmmm...much thought on this. Not to go back to square 1 (since I've been there for what seems like 10 years) but b/c of certain room width AND length limitations, it constricts me leaving fewer options for a good ratio. Believe me, I don't want to fuss about ratios, but to rework the plan for the ceiling to be normal would create a serious mode issue. I have about 10' 2" ceiling space, and can make use of all of it IF I build the ceiling inside out, but b/c of existing water pipes etc, I can't make it a normal ceiling without bringing the ceiling height down at least 6 inches. Which creates that mode issue....., and to step into another viable ratio calls for the ceiling to be 8 feet, which is okay I guess, but would make the room way smaller than I can potentially make it. And I'd like the opportunity to have a cloth covered false ceiling with acoustic treatment in between the joist. There'd be just enough room to get in there with a drill and a tired, exhausted human arm. going in circles :? The panels idea seems great, but as what I think you're saying, and considering I too am a solo builder, the panels seem costlier and far more effort involving. Who wants to put in effort these days? I made these illustrations for myself so I don't go crazy visualizing everything. But it also explains EXACTLY what I'm encountering, or about to be. I figure this would also meet firecode. Any thoughts? Am I about to build something that will severely reduce the walls integrity?

And nowwwwww, come to think of it...I'm not sure that I really want to cover all of my ceiling space (exposed/inside-out) with absorbent insulation. My room will be pretty small, and with the treatment that needs to go in the room anyway, adding a totally false absorbent ceiling will be coming close to an anechoic chamber. The room is: W = 7' 2" L = 12' H = 9' 2" I guess in some perspectives you can't get enough bass trapping, but I don't particularly think a false ceiling will trap bass more than it would prevent unwanted reflection...a whole lot of em, at all freqs. I think I'm headed the way of a regular ceiling AND THEN build an angled false ceiling up to just past the listening position.

Isn't there a possability that one could utilise the false ceiling avenue with various materials? In a checkered board like approach. If filling ALL available space between ceiling beams with one particular treatment is going to be creating a problem, perhaps other materials could be used up there as well. In the end you could still have one monolithic looking fabric covered ceiling if you wanted, just with different fill. Just a thought :)

good point. Not sure if diffusers would be of much help in my small ~700 cu ft. room. Hanging slat res's, not sure f that's up my alley. You make a great point though.

Insideout building sucks (in terms of how much hassle it is), so If you have the space to avoid it, do it A cloud over the mix position will do the job, and if you want, you can add a hard surface behind it so you can angle it and remove unwanted reflections over your mixspot

javier - how much building experience have you had? yet keep whining about inside/out construction because you built one small room yet Demetris built his whole studio inside/out without one complaint. the saving in materials and space is well worth it. http://johnlsayers.com/Pages/nuevo.htm#top

Danny - the idea is to build the ceiling in modules around 900mm wide which is a standard drywall sheet width - you lift each panel up into place and then seal the join between panels.
