We screwed up. We built out an interior wall to hide plumbing and didn’t insulate for sound proofing. D’oh! So now we’re trying to come up with ingenious ways to control noise without ripping out the area in question.

There are a few solutions:

1. Build the wall out more. Use a drywall such as Quiet Rock or insulate and use regular sheetrock. Since we’re terrible at taping, we don’t like this option.

2. Blow in insulation. This isn’t feasible for us as there isn’t enough space between the pipes and the wall.

3. Cover with cork or fabric. Homasote offers both options as well as other sound proof wall materials.

4. Use a paint such as Acousti-Coat, a water based latex formulated with hollow ceramic microspheres, sound absorbing fillers and resins.

5. Build the wall out with ornate plaster (or fake plaster) detail. The most complicated of all options. And guess what? This is probably what we’ll do. Why? The house has alot of period detail which we’ve tried to match on rooms that needed gutting. Our oversight was a blessing. We now have an excuse to take straight edge drywall and make it look fabulous. We may need to use something behind the molding for soundproofing, but hey, it saves us from taping!

6. Put it off until we no longer notice it. Actually, this is our most likely scenario.

Wait wait wait.. How could building out the wall with ornate plaster be more difficult to perfect than taping seams? The latter I was able to get better at with some experience and patiences, but the former, I’m pretty sure I’d *never* be able to pull off.

LOL. We’re not creating the plaster from scratch….we’re buying a series of pieces. It all comes down to what we like more. We’ll give the plaster more of an effort because it will be worth it to us.
I have more fun with my crazy endeavors than simple plans anyway.

Hah, okay. Would a series of plaster pieces put on the wall help much with sound-proofing though?

That Acousti-Coat seems magical – might have to give it a whirl (our Philly rowhome walls – plaster over brick – are pretty non-sound-limiting’ish.

It’s something we have to look into. We may put a sound barrier under the molding. I know that the original plaster walls are more sound proof than sheetrock, so I’m thinking that the plaster alone should do something. Then there’s the fake plaster. I would never want to use it otherwise, but if it’s an easier/better sound proof solution, I just may consider it.
Do you think this stuff would look hideous?

Hey, try that Acousti paint and lemme know how it goes! 😉
