Willie - they look great - but I also would like to know how you get them to stand up!

I also like the foam and PVC panel Bill - but how do you attach the foam to the pipe?

Melissa,
Sorry. I tried to take a picture yesterday but the battery went dead on the camera. <g> I use a drapery hook. The sharp end goes in the foam and it hangs on the PVC pipe. The arrow is pointing to the hole. With enough PVC you could get creative and make a box if you wanted. Hope this helps.

Bob,

If you can figure a way to perhaps use spray adhesive to "wrap" the heavy fabric around the the 703 or 705 panel without the backer board, it should make for a much more versatile and sound controlling panel. And it would only weigh around 3-5 lbs.
The acoustical theory suggest that it's best that sound be able to "pass through" the panel and not be reflected by a solid backing.

I may try that later. I still have plenty of fabric...or since you are not that far away....get some 703 and bring it up and we'll get my wife to wrap it. Laugh


What came to mind for me was the spray adhesive used to attach headliners in cars. I've done a few headliner replacements myself, it would probably be real similar. In fact that material that is used for headliners with the foam backing might be just the ticket!

Can we get your wife to roll around on it until it dries? Wink

I thought about that and for the board backed panels, reversed L brackets may work. I am hanging some on a three paneled room divider that works great.
As far as support for the board-less panels-- I did think about the peg board but I am afraid that is still too much reflection. I thought about various gages of screen or metal grid fence material. Or maybe a few 2" strips of luan plywood run up the back and secured with adhesive and then wrapped.
But probably the best solution is a box frame around the outside of the fiberglass panel.

While calling acoustic insulation joints in SLC in an attempt to find Owes Corning 703. I had a sales guy suggest this stuff instead:

Anybody heard of it or used it for this application?

Thanks,

Craig

Craig,

I suggest you post it in an appropriate forum at either www.johnlsayers.com or www.recording.org and let the experts at one of those sites give an opinion before you buy it.

You might also try looking for Roxul. They have some comparable products to OC 703.
