neoprene rubber question

Hi, Can someone please advise me on how thick the neoprene rubber strips need to be when placing wooden framing on top? Is all neoprene rubber the same or are there different types? Thanks hally

Could you be a bit more specific? What exactly do you mean by "placing wooden framing on top"? Are you talking about walls, floor, or ceiling framing? On top of what? And why do you want to use rubber under that framing? - Stuart -

no, we can't. Only if you show us the product in question.

as thin as possible. maybe even ribbed! lol

maybe even ribbed!

:) VERY ribbed, I'd say!

Thanks for the quick answers,

Could you be a bit more specific?

I am currently sealing the outer structure of my studio, beefing up between the joists and rafters and will hopefully soon have air tight rooms. I will be building rooms within these rooms using wooden framing. The live rooms are on a concrete slab (ground level) and the control room is above (2nd level). Its my intention to place the internal wall frames of the 2 live rooms on rubber strips decoupling them somewhat from the slab... I will then continue with dry walling etc... I hope this helps... Neoprene seems difficult to purchase here in ireland, does it go by any other name? regards hally

are the timber walls built off a concrete (ground bearing slab) base?

I am guessing you mean is the slab sitting on earth and if so the answer is yes, it is the groung floor slab sitting on the foundation for the building cheers hally

Cement is already an awesome isolator... I built my studio in a basement, wood on concrete no neoprene.. I would be more concerned with how you intend to keep sound out of the control room that sits on top of a live tracking room. That will prove to be much more of a challenge as the sound will have a much easier time going up rather then down.. Do you have any plans or mock ups of what you are trying to achieve?

Hally, It's a waste 'o money and time. Forget about it. You'll have to be precise in calculations/test to know exactly what density/thickness you'll be needing. It has to "spring" if you want it to work. Big change you get it wrong. And, as said, concrete is your friend already. Soundwaves flanking through concrete is not the biggest problem here (there's practically none) so you don't need to decouple your walls. You'll need sealant to seal of the whole wall structure. good luck

Plus, neoprene is REALLY expensive (at least here in the States it is). I ended up buying some scrap pieces to do my windows, and even the scraps here expensive!
