I'm thinking of coving the walls in my recording room fully in corkboard. I record verything in that room. Guitar, drums, vocals, etc.. Is this a good idea or a bad one? Do people typically do this?

Nov 11, 2009 05:15 pm I hate to plug another forum, but Ethan Winer is pretty reputable in the acoustic treatment department and he addressed your question directly. Definitely ignore the last poster on this thread, 'loaf'. 703 fiberglass is supposed to be great stuff, and you can cover it in burlap without affecting its broadband absorption properties.

On the plus side, with enough pins you may never lose paperwork...ever.
Nov 11, 2009 05:42 pm It really isn't going to do much. It's slightly less reflective than drywall in the very most upper frequencies, but it isn't going to reduce comb filtering to any great extent and it certainly won't help in the lower frequencies (which are 90% of the problems in almost any room).

Nov 11, 2009 09:00 pm MM - I found this site: www.acoustimac.com/index....7&Itemid=21
which seems to have exactly what I would need to build the 4'x2'x4" broadband traps you suggested. My questoin would be - any concerns with this pre-made route? If not, would I need to get 2 pieces of the 2" 703 insulation for each trap or would I only use one and leave some room? Meaning I would get the 4" frame but use only one pice of 2" 703 insulation and have roughly 2" of space. Obviously its a huge price difference.
Also, their website says 703 is for high and mid frequency absorption where as the 705 is for lowend absorpotion. Any thoughts? Again, big difference in price. Thanks.
BH_PUNX - Sorry to jack a thread, but I figured it at least is in the same arena and may provide an answer if you dont go the cork baord route.
Nov 11, 2009 11:41 pm You want 4" (at least), you want 4#pcf (again, at least - 6# is better, I've heard arguments for and against 8#), you want to *avoid* frames whenever possible unless you're using a frame as a backing (such as GIK traps, where a frame of 1x2's are employed to create a space behind the trap - But the rigid glass rests *on* the frame, not inside of it).

Nov 12, 2009 05:35 am Well, I don't have anything to add, but thanks for posting that site. Now I know where I'll be getting my materials if/when I ever build a studio, or even after we move into a larger place where I actually have room to place some of those things.
On the acoustic fabric in the site, I was thinking about turning them into curtains besides using them to cover the mineral wool or fiberglass. How viable would that be? Or maybe get a couple yards of the suede fabric, and cover that with the colored fabric. I'm brainstorming here, but I would think that would help a bit for treating the one window in this room...which is to my immediate right. Oh, and not to mention kill the damned glare on my screen in the afternoon >_< The window faces southwest :P Of course, having cats may be an issue, but that would be a bridge to cross when we get to it hehe.
Nov 12, 2009 12:40 pm Fabric is more or less fabric... I wouldn't want that "suede look" stuff, but I suppose some people would (as you could make 'patterns' on it if you like). Anything that would stop the migration of the fibers (almost any cotton duck, even burlap) would work. I've seen guys who simply 'wrapped' the stuff in much-el-cheapo fabric, stacked them in the corners and put up a 'frame' of nicer fabric to face it. That's all good.

Nov 12, 2009 04:54 pm 4" is hard to find. Did I understand correctly that two stacked pieces of 2" 703 is not sufficient?

Nov 13, 2009 03:37 pm Quincy - I have the same question. In addition to that:
I just asked my office manager if they had any extra cubcile pieces lying around from the office move. The only thing they had left over were six 12"x60" pieces of 1" corkboard wrapped in burlap.
So, once you treat a room with broadband traps and bass traps - any value in putting these up throughout the room at all? They look pretty sleek and allomatch, but if they arent worth a damn accoustically, I'd rather not go through the hassle of putting them up.
Other than the DIY traps I will be making soon, all I have otherwise is a bunch of aurelex foam - both the 1'x1' and 2'x4' panels and the LERND basstraps - all of which I understand now arent really worth a sh*t.
Should I even bother putting up these corkboards?
Thanks.
Nov 13, 2009 06:10 pm @ Q: 2x2" stacked is fine.
@ Ind: I think it could be potentially cool, and certainly visually stimulating, to T-Pin them to bass traps. Wouldn't mess things up sonically (in the low end) and would provide a fairly reflective (by comparison) surface, not unlike the rubber diaphragms in some of the more high-end traps. If it works...
As usual, get the low end worked out first. Then add the 'candy' and see how it tastes.
