QUIET BATT Acoustic Insulation

Hermitism

Has anyone ever heard of this stuff? I've been trying to find some compressed fiberglass to make my own acoustic panels for room treatments, but every time I find some on CL, it's too far away. I found someone that has boxes of QUIET BATT Acoustic Insulation. One box contains 3 pieces that are 24 inches wide and 8 feet long (3 inches thick) and he's selling them for $25 per box. Originally cost $100 for this size box. That would make six 2'x4' panels. This stuff isn't stiff, so I'd have to make frames, but I have some leftover plywood in the barn, so that won't cost me anything. I found a website on this stuff and it says it has a NRC rating of 1. So I wanted to get your opinions on what you thought about making acoustic panels out of this stuff. Do you think it would be a good choice?

Here's a link I found that shows this stuff...

Here are examples of my panels using the same material. My Dynaudio's are rear ported and when placed to close to the wall like at LSAF they tend to sound boomy. The panels help tighten and produce clean bass.

Thanks for posting the pictures. Those turned out very nice! Did you use Owens Corning insulation as a back to some of your panels and wood for others? If I did this, I hadn't planned on putting a back on them, I was going to use a couple slats on the back to hold the insulation in place and to staple the fabric to. And use a couple braces to keep the panel square and use plywood or leftover baseboards for the frames. I was also trying to keep the weight down on each panel because I was going to try and hang them like a picture. Is it flimsy enough to where I'll have to put a full back on it? I've read that you are supposed to keep it a couple inches away from the wall. Does having plywood in the back change how it works as a sound absorption panel or is it a non-issue?

I would use cloth as a backing not plywood because then the more you space then off the wall the better they work.

I think I just figured out one of my questions...he's got plywood on the back, Owens Corning on the front, Quiet Batt in the middle. It came to me in a dream. I might just wait until I find some fiberglass...I don't know.

Back to sleep now.

The plywood backing is thin and light, same plywood used as the backing in most entertainment systems. Staples penetrate like butter.
Here are a couple WAF panels in my living room system using tapestry. The insulation is very dense and heavier that all the wood frame put together.

Those are impressive looking! Nice match to the floor rug.

Thanks, unfortunately they were not cost effective, but paid off in the long run with sound a were wife approved "happy wife, happy life"

You know, I used to think about the ladies when I slept, but now I wake up thinking about room treatments. That's just wrong! When I don't get enough sleep, I'm not very good at making "sound" decisions. See what I did there? Nevertheless, I think I've decided on the type of acoustic panel I'm going to use. I'll make sure her clothes are acoustically transparent. Good choice?

If you know a Tin Knocker in your area, see if he'll sell you some Duct Liner. It comes in different thicknesses, and has a smooth, porous membrane covering the face of the fiberglass. It's used to line ductwork, make sound traps, and we also used it for sound dampening when placed in front of active supply and return openings.
