Insulation for walls adjacent to basement concrete wall

[jwilkie]

Hello,

So my home studio project is coming along well and i'm just about done framing. It's almost time to get some insulation so i have a question about insulating walls. I know from Rod's book, and some posts on here that i will use regular fluffy insulation for my double walls adjacent to the iso booth and outside of the studio... Also for the cieling.
But I have three walls that are adjacent to basement concrete walls. So I know I'm not trying to stop the sound here because the concrete walls are there. I will have just one layer of drywall on these walls. But it seems I ought to fill in those cavaties behind the drywall with some insulation. I realize I could get some OC 703, or mineral wool, and that would help absorb some sound in the room. But I really don't want to spend a whole lot on this. Is regular insulation ok for this part? I'm wondering what others have done in these kind of spots.

here are some pics of the project also:

Use the cheapest regular insulation. Oh, and read the stickies and follow them.

Hey I like that advice!

Thanks Andre

I think you should give more information before asking a question based on what you are thinking.

What have you done for your vapor barrier?

A basement, often needs one....unless you are below the equator.

But we can only guess where you are...

I am in Massachusetts. I was thinking I would get regular insulation that has the vapor barrier (vapor retarder) built in and put that retarder against the drywall.

... that has the vapor barrier (vapor retarder) built in and put that retarder against the drywall.

Well, a retarder and a barrier are two different things that achieve two different goals.

But your opinion is that you can think your way through this and you do not need professional help?

You need a vapor barrier....but you should most assuredly make certain you can do these things according to local building techniques.


Probably the worst thing you can do is to dismiss that you are doing something that requires at least several professionals, none of which you are, but you will attempt it just because you can read a web page that has some little bit of information about it?

You and people that think like this run the risk of health hazards and structural issues due to the inexperience you possess and the willingness to believe that just because one says it on the Internet...it MUST be true.

No Mr. Space I'm not a professional. But I am working with professionals on this project. One of whom is a builder with 30+ years experience building in my area. They know how to finish a basement here, but aren't familiar with all of the sound-proofing techniques such as in Rod's book. That is why I asked about the type of insulation to use... I'm gathering information well before I do anything. And of course it will be done to local standards/regulations.
I don't appreciate your insulting tone with all this. Seems like you get a kick out of labeling people as clueless amateurs. Don't go assuming that like a jerk.

Don't go assuming that like a jerk.

So your solution to someone insulting you is to insult them back?

Relax and show some respect, after all your a newb on here.

I think the point Space is trying to make is your 30+ year builder should already be informing you about proper use of retarder and barrier.

But since your messages are coming across as umm... inexperienced, Space is just trying to give you a wakup call.

Better to be insulted with some good advice than be lied to.

Good luck on the project. 8-)
