Alternative to MLV?
« on: October 28, 2004, 07:30:20 PM »
I live in Canada, and no one here locally knows anything about mass loaded vinyl. Needless to say, mail order would break my bank balance.

Has anyone tried blue 'ice and water' shield? This stuff is readily available, about 1/8" thick, quite heavy, has a self-adhesive backing, and is made of a tar like substance for waterproofing roof eaves, skylights, and so on.

I've used it as acoustic matting in my car, and it functions well to prevent panel vibration.

I was thinking of applying it to the existing exterior wall (inside) before erecting a second gyproc wall on resilient channel. Anyone ever tried it?

Im not sure this would do the job, first I think you would need 3 layers to equal the density of 1 layer of MLV.
Even then, I'm still unsure of the results.Also if you have existing drywall you will need remove it before you can use RC channel or open up holes to avoid a reverberation chamber.
