4" Owens Corning 703 Fiberglass Acoustical Board is a highly rated absorber for all ranges of sound frequencies.  4" 703 Fiberglass panels are very good at absorbing Low, Mid, and High sound frequencies as the Acoustical Performance Chart below illustrates.  These 4" 703 Fiberglass panels are used as the core insulation for Acoustic Bass Traps.  These Bass Traps are placed in the corners and on the back walls of home theaters, sound studios, media rooms, etc.  

4" Owens Corning 703 Fiberglass panels are inserted into a 2ft x 4ft frame and then wrapped with acoustical transparent fabric and fastened to walls/ceilings with panel hardware.  Bass Traps are traditionally placed catty corner in the back corners of a room and are also placed on the back walls opposite of the sound source.

    Great for superchunks.

    Posted by Rick D. on 8th Mar 2019

    I bought 4 boxes of this for what I thought was going to be 3 superchunks. I ended up using most of 2 boxes for the first one in the front of my room. It works really well with a custom made diffusion panel I created with a sheet of pegboard drilled with 2", 1", 3/4" and 1/2" holes. Better GFR ratings will get more low frequency. 703 is awesome IF you put a membrane in front of it. Will use the remaining 703 for cloud panels: 8" x 24"x 48", mounted directly flush to ceiling. These will have the same custom made diffusion/scattering plates installed on 5 panels. Great product, used by studio builders everywhere forever.
    Great product and price, service was fast and accurate. Shipping was timely and undamaged.
    Good Job.

    Good Company

    I decided to go with Buy Insulation Products because I needed Owens Corning 703 for acoustic clouds I was building for my recording studio. I looked at different options, including local ones, for getting 703 and Buy Insulation Products offered the best price. Their communication was professional and clear and the 703 arrived when they said it would. I'm very happy with this transaction.

    *Chris, we are happy to hear you are pleased with our product and service, best of luck with your sound clouds ~BIP

    OC 703: Great price, prompt shipping (12 boxes), good communication

    Posted by DW on 16th Jun 2017

    I checked around quite a bit, both online and at local stores, to find a good price on OC703 for my studiio build. In the end, I chose, despite the rather hefty shipping costs of such a bulky order (12 boxes, each 2'x4'x1'), because to beat that all-in price would require a truck rental and the better part of a day's effort and travel. And that would have only saved me $60. One thing I worried about was the condition it would arrive in: it's not hard to tear up a large box of 703 using a commercial shipper. There was only one box that was ripped up a little, but the product was fine inside. There were prompt in answering my questions regarding shipping times, which is important, as it allowed me to efficiently budget my time spent on this studio build. I wouldn't hesitate to do business with them again. If you don't own a large truck, and live rather close to a bulk supplier of insulation products, I'd suggest you check these guys out before you purchase. Even if you do, for that matter- their price on 4" OC703 was significantly better than everyone else.

    5 Boxes of Owens Corning 703 Fiberglass Acoustic Board 4" (15 total pieces)

    Posted by Mark B on 12th Jul 2015

    Not only was your bulk price for 5 cases of the 4" OC 703 the best I was able to find, but your combined shipping cost for the 5 boxes was also less than anybody else I could find after several hours of searching online. And it arrived quicker than I anticipated (6 days after I placed my order). I was concerned at first that you might have inadvertently sent the 2" version of the fiberglass (because the original stickers on each of the 5 boxes said they contained the 2" version), but I was impressed that I got an e-mail response from you within 2 hours the evening before the 4th of July explaining that the 4" version had to be re-packed into those boxes for UPS shipping purposes. If these work as well as I expect them to (for acoustic bass traps), I might need a few more. If so, you'll definitely get my future business, too.

    Mark~ We are glad you are happy with our product and service, and look forward to seeing the end result of your project! ~ BIP
