Treat my room with 705 frameless traps: Who will accept the challenge?

Reluctantly bringing soem work home. I have to choose between a couple of rooms for setting up some gear. Composing / Light recording and mixing. I made a blanket fortress for the occasional recording. However, I am about to purchase some 705 and throw in some traps.

I have two options:
24 x 11 x 9 Semi open Floor Plan (thought of hanging a moving blanket over the opening which is about 5 1/2 ft wide)
or
15 x 12 x 8 Room with door

These will be frameless. Not going to fully treat the space. Just going to try and tighten things up a bit. I will have between 24 and 30 2" 705 panels and some burlap at my disposal, along with a few moving blankets if you need them.

Choose a room and config for panels. You can do anything but suggest bulding frames. Any thickness any reflection point, any bootleg mounting idea (including just sitting them in each corner on the floor), almost anythign goes.
Go!

I could treat that room with 7 bundles of 705 and a case of good scotch.

(j/k but I thought it provided a good counterpoint to the quote in your sig)

Ha! I love it!

Maybe I should just treat my room with 30 cases of good Scotch? I am open to new acoustic materials, as long as they don't require frames..


Yikes! Looks like I should have posted this in the Bass Trap subforum perhaps?

I don't think it's an issue. The mods will move it if they want to. A moving blanket will have limited impact in terms of isolation. I've made gobos that were a snug fit for a room opening and they worked pretty well. Too bad the 9' tall room isn't the 12' wide room. Being a DIY freak, I'd build a wall with a door in the 24' room...

Blanket is not for isolation per se.
That area opens up to a hallway, and I figured throwing something up may help dampen some echoes from traveling down and back.

If it were a serious recording space, I would DIY. One of those is available by day, this setup is for when I come home and decide that to document an idea or two.

I would opt for the larger room (we always want the largest room!).

I would make all of your traps no less than 4" thick. Just double up the panels when you wrap them. You can use spray adhesive in patches to keep the two panels together (you can also use that to tack your fabric to the 705.

I would do panels at each first reflection point at your mixing area (including the ceiling), along with trapping in the corners, floor to ceiling. Possibly on the wall/ceiling corners if it was needed. I would use the rest for spot treatment around the recording area.

You can use impaling clips to easily attach the 705 to walls. If you used these for the ceiling, I would recommend using some adhesive on the impaling clips to keep them on the ceiling.

Generally agreed with Alexander, though I think 2" panels generally suffice for first reflection points. There is a good argument to go 2" at those locations, which frees up more 705 for mo'betta and/or thicker corner bass traps.

If you go with 2" then space it off the wall a few inches. Needless to say you are only using 3 more 2" panels so I think it is worth the few extra bucks.

I suggested going 4" as he will have a healthy starting amount of 24-30 batts of 705.

At 4", 703 would be a better choice.

Hmmmm.... Choices choices.
I could get some 703 with the edges hardened for frameless mounting. I figured the 705 would be an overall better choice for no frame panels though. Hmmm maybe I can spot glue the hardened edge 703 to 705?

How bad a reduction in efficacy are we talking here?
(BTW My original idea was to do 6" corner traps plus whatever refelction points I can muster)

Basically, the more space you have, the less dense you want the material to be. OC705 is really only best when you have maybe 2" to work with and no space behind. For a corner trap where you have a foot or more in depth, pink fluffy is better than 703 or 705.

Every application has it own best solution. There is no one product that across the board does better.
