Has anyone made their own acoustic panels by following Jon Risch's instructions at:

http://www.geocities.com/jonrisch/a1.htm


???


If so, I need your help. In his instructions he mentions using 6" or 8" fiberglass.


Excuse my naivete, but is he referring to the same fiberglass one buys at Home Depot for home insulation?


My acoustic panels will be 1" - 1.5" thick. That said, do I just simply compress the 8" fiberglass down to 1" - 1.5"?


Also, he refers to "Rock Wool". What is that? Where can I get some?


Again, I'm clueless here. Can anyone help? Thx!

Leo,

You need to go to your local lumber yard or insulation company and get JohnsManville, Knaus or Owings Corning semi-rigid fiberglass insulation. Some come with a black backing like insula-sheild. It comes in 1", 2" and 3" thicknesses usually (4 foot length is standard), with obviously different sound absorbtion specs. I used the 2" Johns Manville and it works great.

It starts off as 6" or 8" fiberglass insulation that is compressed and held by some sort of resin. It's easy to cut. Just make sure if you get the unfaced type that you cover the back as well as the front.

Good Luck,

Dom
