Source for Owens Corning 703 for DIY??

I'll add one more thing...

Don't get too hung up on Owens corning.

There is nothing magical about this stuff.

There are a handful of manufacturers that all make comparable products. (Johns Manville comes to mind, also knauff)

the 2 most important things in acoustic treatments are
-quantity
-placement
quality of the aborber is really not an issue so long as you keep things reasonably comparable.

again I cant stress enough - what you use will not really matter that much in relation to how much you use and where you put it.

if that were not the case, realtraps and GIK would be selling some $1000 trap that you only need one or 2 of. but they'll be the first to tell you, you really need more than a few traps, and it makes a difference where you place them.

While I'm on the topic of GIK - they are a forum sponsor here - that means they help contribute to keep this forum free. The sell panels for as little as $60 each. I've built DIY panels before - they always looked bad, did not come with a return policy, and in the end cost me way more than I thought they would. So if you're just getting started -I'd at least consider them...

basementjack and altenberg,
Thanks for your inputs. I am very interested in the acoustical cotton provided it's cost is not considerably more than fiberglass. I'm not hung up on OC either. I realized long ago that OC, Knaupf, Certainteed etc were essentially all the same. I do like the idea of working with cotton though and it's performance seems a little more broadband.

BTW, I alrady own a couple of GIK absorbers and I am very happy with them - they serve as absorbers behind a pair of speakers in a small room. I just know thjat I need a lot more to do my HT and I am looking at the DIY option to contain costs, so the cotton may not make the cut based on that factor...
We'll see.

At this point I still have to find a source for ANY of this stuff. Yeah, I know, do some legwork, it's out there! I guess I'm too used to going to HD, Lowe's or my local hardware store and picking stuff up on my way home.
BTW, my local hardware store wipes the floor with HD and Lowe's as far as hardware prices, i.e. nuts, bolt, nails etc. not to mention convenience and having employees who know what their talking about...
Rant off:rolleyesno:

For people here in in the NYC metro area, I typically recommend J&S Supply Corp. (http://www.jandssupply.com/). They deliver within the tri-state area, though I imagine that might be something for larger quantities -- but they could probably send you a few boxes or whatever via FedEx or UPS ground for not too much money.

I've dealt with them myself a number of times in the past for some DIY projects, etc. They are very good guys to deal with, and their prices are usually quite reasonable. They are actually a wholesaler (though we don't get our stuff from them), but they will sell smaller quantities to individuals as well.

I know they stock OC 703 and 701, and they will order 705 for you if you want it. They also carry Johns-Manville and Certainteed products.

Definitely worth at least a call to see how reasonably they can get what you need delivered to your door. You can tell them I (or Ethan) sent you, and that you are building bass traps.
