Yeah I saw that thread. I saw on gearslutz that people got owens 703 for like .50 per square foot.

I was hoping to get that price. I can get the Knauf(703 equivalent) at Viking for about 1.18/SF.

Already called them. Ive been searching a lot. Was hoping somebody knew about the lower rates.

Anybody know a contractor in L.A. that can help me get a contractors price?

Thanx-

Well there is a close place to me that sells the Knauf equivalent to owens cornign 703 at about 1.19 per square foot.

Is the knauf stuff as good? Looks like it is a good way to go cuz they use more eco friendly products to make it and has no phenol, formaldehyde, acrylics or artificial colors.

Just bought 9 6 piece boxes of Knauf.

Something tells me this is one of my best musical investments Ill ever make.

Taking pics, building tomorrow I hope-

Will post!!!

15+ hours into the project, finally borrowed a friends drill so I have the screwdriver drill and drill bit drill going- makes things way faster.

I got some stretchy black material that air goes through better than burlap but has smaller holes in the knit. I like stretchy. If somethign rips, I can stretch and staple.

I got pics. Will post them all when whole project is done-

1.50/yard for the material (black burlap was 4.50/yard- Gotta love the downtown L.A. fabric district!

lol

Yeah went with 1X2's.
I dont mind the rounded corners but yeah Im going to try to keep them square.

Any kind of omni mic will work - even the mic built in to a Radio Shack SPL meter if you happen to have one of those.

Yeah, it's a handy little device and won't break the bank.  I think they go for around $40.

Obviously, you need to position it in your normal mix position at ear level.  I used a camera tripod.

hmm, nice to know Im already within 10-15db on the response-  still got 20 panels to place! lmao

POST #96 and #97

I purchased 8lb rockwool.

For the music room I have been using plastic drywall corners for the frames. 2'x4'x4" : 2 pieces of rockwool. These take a lot of time to cut, rivet,... But the exposed surface area is about 30% more.

For the dance studio I am using 2"x4" wood frames:  2'x8'x4" and  4'x4'x4"  both of these have single layers of rockwool.

I used 6" plastic corner pieces to space the 2" rockwool pieces in the center of the 2'x4' frames. Then covered with a layer of "bedsheet" material, and then a layer of synthetic felt material, purchased from Hancock fabrics.

Still got a bunch of panels to make. I have not noticed any "shedding" yet. But I may try the plastic wrap technique just to be sure. I figgered the two layers of fabric would be enough to stop the little bits from escaping. But, whose nose?

The craft felt I am using:

I was mostly curious because you indicated particles were coming through the material, even though it appears you have a 2nd layer on the faces of the panels.
