Ready to Build but have a few Questions about Wall to Wall

Hey all, First post but like most here for a while. Great Site!!!! I have a huge warehouse space with 25' ceiling. Wide open space. So i am planning my new facility. I have read about all this site and can't find anything on wall to wall construction. I will use the diy wall to ceiling mounts. but what about wall to wall in the corners? I will build a shell on existing floor capping off with 2X8 ceiling joist. rubber under joist on top of "shell" wall. This will be leaf one from outsde to inside- 5/8" rock 1/2" rock insulation Then I will float floor on rubber. build next leaf on floor with following from inside "spring" to inside control room. insulation 1/2" mdf 1/2" rock My questions are this: Do I build the inside leaf of ceiling by resting joists again on walls with rubber under? Plus if i rest joists on rubber doesnt the screws or nails going from joist to wall negate the rubber? How do i connect corners of walls? use rubber then nail? but then the same questions of above? Thanks for all the help. i haven't begun building anything yet, so all is open. No pix nessasary cus it's just a big wide open space in a warehouse. Thanks again jai

Jai, first let me welcome you to the board - second, sorry your post managed to elude me, not trying to ignore you :? I'm short on time til much later tonight, I'll see what I can do at that time. Meantime, if you've not already done so please check out the "stickies" at the top of the page, especially "complete section" - I'll get back sometime late this evening... Steve

Hey Steve, Thanks for the reply. Well, i guess we can forget about this post. I just found out that my partner passed on that big nice warehouse for an industrial strip center. :( So, please look at my next post. Sorry for the confussion. jai
