Owens Corning 703 Semi Rigid Fiberglass Board Sound Absorbing Thermal Acoustic Insulation, 2 Inch Thickness (6 Pack)

As someone deeply invested in optimizing my studio's acoustics, I can confidently say that Owens Corning 703 is an outstanding product. I purchased it to create two 60 x 90 cm acoustic panels for my side wall first reflection points and to replace the low-density mineral wool in my corner bass traps. The acoustic improvement has been nothing short of remarkable. From the moment it arrived, I was impressed. The product came in excellent condition, and working with it was a dream. Unlike the messy, low-density mineral wool that sheds dust everywhere, the 703 is much more rigid and incredibly clean to work with. Cutting it felt like slicing a wedding cake – smooth, precise, and genuinely pleasant. This material is incredibly easy to handle, making the DIY process a breeze. Even better, I was able to use three scraps from my bass trap cuts to make these two panels, which really speaks to the efficiency of the material and minimizes waste. I'll be attaching some photos of my panel construction, which hopefully showcase just how well this material performs. I am definitely buying more to complete my corner bass traps. If you're serious about DIY acoustic treatment, look no further than Owens Corning 703. Highly recommended!

Good quality, I build a dozen or so acoustical panels for my home theater and very happy with this product

These panels do an excellent job of absorbing unwanted echoes, yielding a clear, concise sound. I bought these to tame noise at the top of my stairwell (3 level townhouse with a stairwell visible from all 3 floors), tame noise from my furnace room, and to experiment in my home theater room. I held one panel up for my wife at the top of the stairwell and asked her to clap her hands. She couldn't believe the difference in sound, and agreed they would be helpful (project approved!). It made it easier to understand what the other was saying. However, proceed with caution: These panels are made of fiberglass. Uncovered fiberglass is extremely messy. There is a warning label in the box explaining the protective gear that should be worn: gloves, respirator, eye protection. You don't want tiny little glass splinters in your hands that you cannot see but can definitely feel. You should not be considering these unless you are comfortable with 'do-it-yourself.' Compared to the covered panels, I'm having second thoughts about going the economical, DIY approach. I calculate I can make these myself for about $42 per 2'x4' panel, a savings of $23 per panel. Factoring in the mess, time, and hassle, I'm thinking the pre-covered panels may be the better way to go. YMMV. I have foam eggshell panels also. I held both up in the same spot in the stairwell and performed the same tests on both. To my untrained ear, the foam panels absorbed higher frequencies, but didn't work as well on lower frequencies. The fiberglass panels absorbed more sound, and absorbed sound over a wider frequency range (mid and low as well as high). These fiberglass panels significantly outperformed the foam eggshell panels. My bias was to the foam eggshell, since they would be easier to deal with. Whether you go with covered panels or with these bare/DIY panels, I recommend both, and either will yield an improvement. Final note. If you are a man living with a woman, or a man who plans to one day live with a woman: No woman will ever allow these to be installed anywhere in her home if you plan to continue living together, and no woman you would like to live with will ever be impressed by sound absorbing wall panels hanging in the living room. Look at the user submitted photos and tell me how sound absorbing wall panels fit in to the Ethan Allen decor.

Used these to make sound panels in a small home studio, using frames and acoustic fabric covers. 6 of these worked perfectly to eliminate reverberations when recording. Soundproofing the room would require a lot more insulation. Note: this insulation is less effective at controlling bass (that requires a bass trap).

Awesome material for acoustic panels.

I used a single panel cut to 24x30" mounted on the wall behind an Kawai K300 piano to dampen the sound and it works wonderfully. The setting is large dining room, tile floors, vaulted ceiling, mirrored wall opposite the piano. I found myself using the soft pedal excessively while playing in order to compensate for the bright, lively room. One panel, uncovered, mounted on the wall 3 inches from the back of the piano and centered on the soundboard attenuated the sound noticeably (though, at the expense of some high overtones).

If you are an audiophile, consider buying this product. I have invested 1000's of $$ on my 2 channel and HT setup but this one beats them all in terms of price to performance. You will be amazed at the improvement in the sound quality right from the Low end frequency to high frequency; worth every penny from my experience.

very very messy, and itchy, wait until cooler weather to work with these boards outside or in a garage. wear long sleeves, pants, gloves and don't touch your face. other than that I love these boards. I've treated my mastering studio with them. they're dense enough to absorb bass in corners and will diffuse highs and echoes if placed properly according to monitor location. just get some cheap fabric on sale, wrap them up and mount these bad boys for a superior acoustic environment at a doable price.
