I am building a new edit studio, and I am having trouble finding rigid fiberglass insulation suitable for acoustic absorption. I can buy online, but many retailers take advantage of the fact that OC703 is sold exclusively to contractors and they mark it way up for use as acoustic treatment.
Maybe you have some unused panels stashed somewhere that you would be willing to give away, or can recommend a source for Owens Corning or a suitable alternative.... perhaps a stack of old 3/4" 2ft x 4 ft fiberglass ceiling tiles that have the white plastic sheet stuck to one side?

They have 703, 705, spray foam, mineral wool, etc. Prices are as good if not better than any on-line dealer. They will sell you as many or as few pieces as you need, including scraps sometimes. They are good people, and have supplied many a studio owner in this town.
FYI, pound for pound, the mineral wool is a lot cheaper and very effective, IMO. Not that you asked.
Mineral wool is harder to work with. Messier. But it's really really inexpensive compared to 703, and it's extremely effective. In a home studio, I think it's the best deal going, unless you're already spending tons of money on serious design work. Then why skimp at that point? But if you're just controlling reflections or doing some isolation work, it works great.
As far as coverings, I've found that Felt is best. It stretches really well, and it doesn't tare easily. Plus, it's inexpensive and more durable than burlap. And it's a lot prettier, IMO. I've used it for my acoustic treatments in my studio. Pictures on my page if you want to see.
Great, thanks again!
This build out is in a portion of an old home I chose with studio space in mind. I guess you would call it a project studio, but I will be sharing it with other engineers and it will see about 50 hours a week worth of work, so I am trying to pay attention to detail. First reflection absorption and superchunk bass traps are what I will be building, perhaps a gobo or two for light overdub work.
Felt is a good idea, and it might keep the fibers in a little better than burlap. When the halogen lights in my old space were on, you could see them floating around in the beam...
That's a good lookin space you've got there... I especially like how you have your gear in road racks, that makes for easy re-configuration when you need the extra space. Wow look at that apple display... It must be nice to comfortably keep the edit and mix windows open at the same time on one screen!
You may be far too young to remember Velvet Elvis paintings found in many Nashville studios over the years. A mural is a large painting along a wall or ceiling. Velvet and Felt are very similar. Get it?
haha oh yes, I know what a mural is, but I didn't catch the elvis reference :) So what you are basically saying is that I need a velvet Elvis Mural... that might be a good way to cover some bass traps!
Insulation Supply Co. was easy to find, easy on the wallet, and loaded my truck for me. I picket up about 160 sq ft of 3" #8 mineral wool and 48 sq ft of 4" for less than 200 dollars. At these rates, there really is no excuse for home recording engineers not to have at least a FEW panels in a room. I made 26. It's the single most effective and least expensive improvement to the recordings you make and mix.
