Me again. Anyone have experience with putty pads for the backs of electrical outlet boxes? Nick, maybe? I'd like to block as much sound from the bathroom as I can, so I thought of using them since I'll have several electrical boxes on that wall between the kitchen and the bathroom. Those will be the weakest points for sound leakage, I'd imagine.

This stuff is significantly cheaper, however, and I was wondering if anyone knew if it would be as effective. I don't care about fire rating, just sound. It seemed like it could be almost the same product, simply marketed differently.
