Got it! Thanx so much man! You made my plans. I'll let you know how it went and take pics when it is done. Thanx, Lance

It should work that way, between your two layers of drywall on each side. It seems that the sound barrier material has a bit higher STC rating though, which would block more sound from getting through. Two reasons for this: Sound barrier material is 1) flexible and 2) heaveier per square foot. Flexible mass is the best way to kill sound. I also noticed that the specs for the sound board state that you need install the screws for the outer layer of drywall all the way though to the studs. This effectively connects the outer layer directly to the studs, bypassing most of the sound deadening properties of the sound board. Installation techniques are just as important as the materials you use.

Not connecting with the studs seems like the outer drywall that will remain exposed could easily become loose... no? Would staggering the outer drywall seams off the center of the studs and using anchor screws be a better choice?

I used course threaded screws. The fine thread screws will only tear up the sheetrock and not grip anything. Staggering is always a good idea. If you plan on slamdancing into your vocal booth you may want to go ahead and put screws all the way into the studs but otherwise two dozen coarse thread screws in a 4' x 8' panel will hold just fine. Use cauking / glue around the edges of the outer later. Anchor screws would work add some additional support. I didn't use them but not a bad idea. Just make sure you put cauking around the holes so it's air tight.

I'm talking about the 3" thick stuff and trust me, HD does not stock it and niether does lowe's. It's a specialty item that comes from places where contractors get their supplies. It also comes in 2" thick 2'x4' sheets but this would only be useful if you are applying it INSIDE the booth, wrapped in fabric, in place of studio foam. Use the 3" stuff inside the walls.

Where do you get this stuff at? This is not your everyday type of material. I have called many places in my area (Detroit, MI) and they don't seem to be any assistance on a supplier. Would you mind providing the name of the supplier that you recieved yours from?

Roxul doesn't seem to be any help either. They don't reply to emails asking for suppliers.

Thanks for any additional information you can give on tracing this stuff down.

I have found many sites on how to grow hydroponics with it. lol! That business isn't as reqarding as music. lol!

Thanks!

You have to go to the Roxul website ( http://www.roxul.com/sw34444.asp ), and fill out a form. They then contact you and tell you where you can get it. I did it and two days later my voicemail had a message with what the actual material I need is and the number to call close to me where I can get it. ,Lance

It took about a week for them to reply when I filled out the form.

Thanks! I guess I will have to be patient.

since starting my quest for the perfect inexpensive vocal booth. I have learned a great deal thanks to everyone and there suggestions.

-A.D.

I have a great website that anyone interested in building a control room or vocal room should check out. http://www.acoustics101.com/index.htm.

P.S. Roxul lead me in the direction of a supplier of their products in the Detroit area.
If anyone is interested in the location I am more than happy to distribute their number. The supplier has all of the material needed to make your vocal booth/control room spectacular! And they have great prices too!

-Thanks again!

Glad to hear you find the place to get your supplies. If anyone needs anything in the Atlanta area let me know and I can help.
