    It is a fine product. Better than using batt insulation. BIP was great and shipped quickly. Kinda pricey though.

    703 is a no nonsense workhorse, and has great service and prompt shipping. I used to get 703 through a Acoustics store through Amazon but the wasnt as fast or streamline. I now refer anyone needing to treat acoustic problems here

    *Christopher, thank you for the great review and the referrals! ~ BIP

    Great price, but arrived dirty

    Posted by Garret K. on 8th Aug 2020

    I previously ordered the 2 inch version and it arrived in fantastic shape. But the 4 inch version arrived covered in black charcoal-like debris which got stuck in my acoustic fabric. Fortunately, it vacuumed off pretty easily. It arrived quickly and at a great price, so I would order it again.

    *Garret, I found out this was charcoal from black acoustic blankets that were cut at the same time as packing up the 703. Our apologies for the mistake and please check for an email from us resolving this with you. ~ BIP

    Outstanding Acoustic Board - OC 703

    Posted by Unknown on 4th Apr 2019

    Having a home recording studio, I was ready to build out a recording booth. After researching several alternatives, the Owens Corning 4" 703 was the best choice. Not only is the sound frequency absorption properties virtually perfect across the spectrum, the price is unbeatable. The quality of my recordings has dramatically increased, I couldn't be happier. I shopped the internet for the best price and found it at Buy Insulation Products. I had a chance to talk with Customer Service, too, and the experience was great - helpful, knowledgeable, friendly. My now go-to source.

    Slap these bad boys in the corner and you're good to go. It's actually pretty surprising how much this stuff can tidy up the sound of a small room.
