Title: Is Wall Mass Useful?
Post by: Terry70 on March 02, 2019, 04:41:06 PM
I'm building a basement music room. 3 walls are poured concrete. The 4th is going to be double stud walls with drywall, etc. I've read some things about wall "mass" and had a thought. I have about 1000 new bricks leftover from our house construction 2 years ago. Is there any value in stacking these inside one of the stud walls to increase sound attenuation? If so, is stacking sufficient, or would they need to be mortared in place. Thanks for the thoughts?

I really enjoy these basement builds, they make for great rooms. With that being said you have a great opportunity to do this right by avoiding some serious mistakes.
Yes your bricks in one of the stud walls is a great idea but you would have to seal them in with mortar for full effect.
For this build you will need mass loaded vinyl and some other products to make the ceiling system reach a high STC rating.
You also need to make sure the inner frame does not touch the ceiling assembly.

Give me a call direct and i will go over a few key tips so you avoid negating your efforts.
