    Here you will find NRC ratings for just about any insulation or absorbtion product on the market... shows ratings for each thickness... thought this might help a few people out...

    I'll start

    Detroit MI area,

    Insulation Sales
    Ferndale, MI
    248-398-7200

    "They carry Owens Corning 703 Unfaced, FRK (foil) faced and ASJ (white) faced in the 1", 1-1/2" and 2" varities." (thanks AjD)

    Aurora IL
    Amerisafe
    http://www.amerisafe.net/store/item....ARTMENT_ID=152
    Sells all sorts of fiberboard by Knauf (Owens Corning competitor)
    NOTE: The website pricing is PER SQ FT, and they do ship via UPS anywhere in the U.S.


    Someone posted a map of locations for a national chain that sells rigid fiberglass that I can't seem to find right now, but if someone has a copy please post that up.

    They've got a bunch of locations scattered across Maryland and Virginia. They were helpful, cheerful, and highly professional -- and that did not change when I told them I only wanted two packages of material.

    Ottawa Fibre products, specifically the OFI-48 and OFI-64 (http://www.ofigroup.com/) are supposed to be extremely similar to the OC 700 series.

    These OFI products are available through ISOFAB at several locations:

    A good friend of mine works for Patene's which is a building suppy company here in Ontario. They dont rep Owens Corning, but they carry what he thinks is a similar product Roxul RXL40. A semi-rigid insulation which comes in 24x48" pieces of thickness 2, 3 or 4". Apparently their min. order would be one bag which contains 64, 48, or 32 sq.ft respectively. This is what I plan to buy when Im ready.

    Seriously, I'm no expert, but the data clearly shows that rigid fiberglass and rockwool do a pretty darn good job absorbing down to the 125 to 150hz range. I'm not sure what you consider the "low mid and bass range," but rigid fiberglass clearly does more than "reduce the reflection of upper midrange and high frequencies." Sounds like you are describing the performance of foam.

    On Ethan's site, he explains: "705-FRK that is four inches thick and spaced 16 inches away from the wall can be quite effective to frequencies below 125 Hz." He also has data showing that higher density provides better absorption at the lower frequencies.

    Check out Table 1 on Ethan's site (it lists absoprtion coefficients):

    http://www.ethanwiner.com/acoustics.html

    Check out Page 2 on this website for rock wool absorption coefficients:

    http://www.fibrexinsulations.com/pdf...uationFire.pdf

    I do believe that sealed bass traps like those described (and manufactured) by Ethan provide absorption below 150hz, but stating that rigid fiberglass panels only absorb the upper-mid and high frequencies is just plain wrong.

    Good idea. For rockwool in Canada, (or possibly elsewhere) see www.Roxul.com The Safe n' Sound product is the best.

    This is the best overall solution!
    the stuff is soundproof with just one sheet Comparable to over eight sheets of drywall.
    this stuff has some special threads or something that convert sound to heat then there is a metal sheet laminated between the qypsum to stop the heat.
    THX certified
    check out the specs @ www.quietrockonline.com and don't forget to mention supertech I'm gonna need more!!!
    thanks for the info on the doors too.

    helpful thread here: *STICKY* Where to Buy Rigid Fiberglass

    I purchased useful panels to hold the fiberglass from www.modularacoustics.com, then purchased Roxul Safe n Sound from Home Depot. Very affordable solution, and good guy to work with.
