Hey I like this place!

Been recording in the basement for a few years. ProTools DAW system. But finally we're making the jump. We have a 24x40 steel building out in the woods. Power just got in and framing has commenced on a 16x18x9 tracking room and 8x16x7.5 control room. Box in a box concept with 2x6 framing throughout. The layers are as follows. Exterior steel skin on 6x8 framing sheeted with 2" sytrene on the metal. 5" dead air space, layer of 5/8 rock, vapor barrier, batting in 2x6 cavity, 1/2" OSB, 1/2" rock, canvas skin, and some ancient cleaned up barnboard 1x stock in varied widths gapped slightly.

The partition wall is 2x6 plates with 2x6 studs set sideways and doubled. Basically 2 walls with common plates. Layer from tracking towards control room is barnboard again, canvas, 1/2" rock, 1/2" osb, 2x6, 1" dead air, 1/2" rock, batting, 2x6, 1/2" osb, 2 layers 1/2" rock.

Control room floor is elevated 18" and we're not quite sure how to insulate that yet. Suggestions?

Now we kind of flew by the seat of our pants with some limited studying and research and made due with some materials we already had. We're dealing with the parallel walls with hinged large treatable panels in the tracking room.

Sooooo.....let me have it! How did we do and did we F UP major on anything? I will post pics as soon as I have some.
 
everything sounds good so far. Make sure everything gets caulked, even where you put the screws in, it cant hurt. What are you doing about windows and doors?
 
Thanks for reminding me to BUY MORE CAULK! We're gonna use a ton of the stuff.

The rough openings were topped with 3/4 plywood floating on 1" certifoam. These "sub" jams were screwed securely to the 2x6 on-sides. This and the top and bottom plates are the only "mechanically" connected pieces of the whole wall.

The window will be 1/4" glass I believe. Two panes angled 5 degrees out from each other with 1" spacing at the bottom. The jam is still a discussion as I've been tempted to use some of that new engineered lumber. It's easy to machine and much more dense. I haven't convinced my cohorts on this yet. Opinions or help would be great.

The door (between control and tracking) will be constructed from a 2x6 subframe laying flat with mitered corners. Once square, we figured maybe a layer of 1/2" OSB each side, a layer 1/2" rock each side, and then a nice 1/4" birch ply each side for a skin. Not sure if I should leave the air space in the middle or fill it. What with? Of course somehow we need an overlapping lip type seal. Still on the drawing board.

Basically the same idea on the egress door but this will be a double door to allow room for wheeling in gear.
 
Day 30

Here's where we're at. We took all our sheetrock scraps and put another layer on the control room partition wall. The photos aren't the best.

"The window will be 1/4" glass I believe. Two panes angled 5 degrees out from each other with 1" spacing at the bottom." - Sooo, do you NOT need any serious isolation or is this a typo? That combination will be lucky to give you STC 38, with low freq. isolation down around 17-18 dB. Meaning - drums will squirt through that window like it was a screen door... Steve
 
More research!

Ooops, typo and ignorance. Make that 1/2" on tracking side and 3/8" on control room side. Steve, any helpful links or info regarding window building would be greatly appreciated. I did a search here but came up empty handed. I'll admit that the window was a weakpoint (gross understatement) in design. We're still in the rough stage so anything can be changed (minus the RO).

Hey ya old fart. Good to see ya here. As if you don't have enough to do...what happened? Someone give you some time off for good behavior? :D
 
Pulled my reading glasses out of my.....

talk to you in a week or so....where the f*ck are my specs?!?
 
It all sounds good so far. In addition to the previous statement on caulk I can only offer two more.

First, be constantly on the lookout for flanking paths and penetrations like outlet boxes. It is easy for a small error in this regard to wash out a lot of expensive construction.

Second, watch your HVAC design. You have made no mention of it yet. So unless you enjoy suffocation you have to take your nice isolated box in a box rooms and punch two big holes in them (one for supply, one for exhaust). Do it wrong and you might as well have a square foot hole between the two rooms.
 
Oh yeah, we need heat! -5F this morning!

Electric baseboard heat. Squirrel cage fan pulling in fresh air through a baffle box. Control switch will be in the control room. One entry and one exit in each room.
