I own a custom electronics integration company that specializes in home cinemas, music studios and media rooms. In my humble opinion, these are the real deal. Foam For You provides VERY dense acoustic foam treatments, not the thin, lightweight material found on Amazon. This is USA Grade-A commercial grade acoustic foam.
I have purchased various acoustic foam over the years from Parts Express and Amazon, that foam is NOTHING compared to FoamForYou. FoamForYou also has foam material data sheets that may assist you in configuring the NRC rating. If I was to make one suggestion it would be to add the NRC to each of their acoustic products.
In full transparency, there were some minor defects in some of the foam. A few superficial holes and a small incomplete or torn section off the back of one corner piece. These defects will not be noticeable when installed; nor with they make any discernible impact on performance. The same defects were also noted on previous Chinese foam products purchased elsewhere.
SUPPORT AMERICAN BUSINESS!
I get the feel that FoamForYou is a smaller company, which is a GOOD thing! Call them and you’ll speak to a human! Things sometimes run a tad slower in smaller companies, so don’t expect the “AMAZON conglomerate speed of next-day, shipped it to ya yesterday” orders. My order took a few days to fill and ship, and they were out of Red foam blocks; but that really didn’t effect me negatively.
Glad I found them, and from now on Foam For You will be our go-to source for our residential and commercial A/V projects.
