D&A Studio: Basement one room studio contruction

Hi Everyone, Work has begun(couple months) for an all in one live and control room(small basement room). Room dimensions: 22’X 13’X 7.4’ Any comments greatly appreciated.

3/8 backer rod installed and applying acoustic sealant(OSI SC-175) on first drywall layer.

Hi! Looks like we are at the same stages in similar rooms, do you have any specs/drawings of what you plan to do in your room. I'm doing a decoupled two leaf system, my control/live room is going to be 16x14x8' 2" RFZ design. Just finished my beefup and built my first wall last night! Allen

Thank you very much Allen. I never thought caulking the joints would take that long :) I'm still debating on the design, RFZ design or just a regular room and just add corner traps etc.

Completed second layer of 5/8 drywall between ceiling joists this weekend and now started applying acoustic sealant caulking again. Next step would be to install drywall at both ends between ceiling joist for isolation to side rooms. Still trying to figure out how to do that. I'm able to screw drywall to the center beam but not sure if I need brackets on top and sides for better support or its not needed, it will be small pieces so maybe it wont. Any suggestions? Thank you.

Finally finished caulking the second layer of drywall(brutal....:)). Now installing cleats, I'm putting spacers before the cleats that way it doesn't put any pressure on the caulking, i'm sure it doesn't make a difference but makes me feel better :)

Looking good! - Stuart -

Thank you very much Stuart. Started working on the silencer boxes:

Adding duct liner.

Looking good! - Stuart -

Outer walls done and will insulate. Ready to start inner walls.........

Some progress with inner wall frame and new 2X8 beams in between original beams, about 1.5 inches below.

:thu: I love to see studio builds moving forwards! - Stuart -

Thank you very much Stuart. Stuart, I will do the method where you recommended for ducting: "Another way is to break the wooden "duct" in the middle of the wall, leaving a gap, and wrap that gap with rubber (Neoprene, EPDM, Sorbothane, etc.) That way, you don't need to worry about isolating the duct and register from the inner leaf: each part of the duct can be attached to its own leaf, and the rubber decouples them." Question: would 1/2 inch neoprene wrapped around twice making it 1 inch of rubber ok? and is 1 inch gap between the ducts sufficient? Thank you.

1/2" should be fine: there's pretty good mass and resilience with that, but of course two wraps to get 1" would be better for the mass, if you don't mind the extra cost. - Stuart -

Thank you very much Stuart

Some more progress, finally :) Finished insulation and first layer of 5/8 drywall. Now working on the second 5/8 drywall layer using greenglue in between first and second layer. Some pictures below:

Started joint compounding drywall joints, yesssssssss, no more lifting 5/8 drywall boards :)

Room almost done and will be posting pictures soon. Below is a picture of the HRV unit I just installed in another room:

Time to buy a computer, etc.... but construction wise done for now..... Thank you all, i learned a great deal reading everyone's comments and information.

There was a glitch with the forum server yesterday, and your photo seems to have disappeared into the depths of cyberspace, with no trace! Please could you re-post the photos. - Stuart -

Offcourse, no problem at all, I only have one right now but will post some more soon:

It's looking pretty darn good! :thu: How does it sound in there? Have you done any REW tests? - Stuart -

Thank you very much Stuart for the kind words and for all the help. I don't have REW tests yet but definitely the room sounds great! Hopefully soon will have more pictures and information.
