OK, I have been doing quite a bit of research this past week on the room treatment front. I am still debating on whether to simply by the end product from one of the many retailers out there or to build my own. There are 2 reasons I want to build right now, one is cost, and the other is so I can experiment more and learn more about what is going on. Buying the higher priced products isn't going to let me experiment as much.
So, I finally found the fiberglass materials, looking online and actually calling Owens-Corning to get details. Their website is quite a maze to find what you want. They even had a specific Acoustic-block line but it isn't available to consumers. So, settling with the 700 series and it looks like it will work well. But, know I have hit a wall... the fabric.
How crucial is the fabric at this point. I know I don't want a reflective fabric, but don't want to spend $15-20 / yard on Guilford Maine stuff, and I can't find anything else for this specific application. It looks like a fairly open weave polyester is the way to go. I can get some of this stuff for $2-5 / yard. I would guess the lesse expensive would be cheaper and less dense material, all the better. But, does anyone else have information on what to use or where to find it. If I splurge on the Guilford, I might as well by the manufactured panels.
