"should" be an easy question

do to financial obstacles, building my live room is going to be a multi-step process... firstly, constructing the walls and ceiling properly, ive got this under control i believe, as well as what i plan to do for treating the room internally for absorption and diffusion... the question comes in regards to the floor. it's a concrete floor (garage). i just wanted to run this by a few people here. im throwing down cheap carpet to get it started quick, and then i want to build the floor. since i want my floor to "float", do you see any problem with building a floor later?? neoprene, framing, wool, and wood flooring and have it just almost touch the walls...and fill that in with acoustic caulk or some relative product??

Floors can be done that way, you'd actually use Celotex or similar material as a perimeter isolation board, but how do you know you need to float your floor; specifically, what sounds are you trying to stop? I've yet to see a plan posted, so not sure how the rest of your proposed construction compares - as in, "weakest link" theory...

yes, ive still yet to post a plan, i should draw one up and let you guys have the final crack at it. from what i've read seemingly numerous times, floating a floor is going to be a good idea if you are trying to isolate the room and you're gonna be tracking drums... ASIDE from just that generality...if im going to be building a floor from the concrete up, it's not going to kill me to float it

I'm stealing this bit of text verbatim from another thread I posted on recently... Here is a very compelling post from Paul Woodlock on the pointlessness of floating lightweight floors. If by chance you don't recognize Paul's name, then that's more evidence that you have more studying to do on the subject. ;-) Check out his monster thread at StudioTips. Plan on spending a few days reading what he has gone through to do a proper heavy floated floor system. Also, don't miss this post from Rod Gervais on the "trendiness" of floating floors (actually, slabs in this case). If you don't recognize Rod's name (or even if you do), then definitely buy his new book. Bottom line: you can't just assume that floating a floor is going to be better than not floating it, because you have to take into account so many factors, including resonance frequencies, the risks of overloading and underloading your elastomers, and especially the combination of both -- bad resonance issues combined with a floor that doesn't actually float due to a lack of "springiness" due to underloading or bottoming out -- the latter being the equivalent of a nasty "drum head" as a floor that amplifies certain frequencies, with zero benefits! :shock: --Keith :mrgreen:

and that's why we ask!! wooo
