Decoupling theory - is hat channel necessary if wall never touches joist
So I'm a bit crunched for horizontal space on my foundation walls and I'm curious if I would need clips and hat channels for those walls...
What makes this unique is that I don't have a top plate nor a bottom plate. I'm adhering rigid foam insulation to the foundation wall then I'm attaching 1x3 furring strips do the foundation wall through the insulation
My question is, if my 1x3 "studs" and double drywall/GG never touch the joists or the floor then would clips and channels make that big a difference?
It seems like the sound would hit the drywall, move to the joists, hit the foundation wall (which would have incredible mass) then move through the foundation to the to the joist.
Thanks,
Joe
