Best Sound Absorbing Material for DIY Wall Panels


I recently built a new house with a dedicated home theater. One of my projects is to completely cover the back wall of the theater (behind primary seating area) with fabric to help with the echo that I am currently experiencing. I have already purchased the fabric (16 yds)and plan on using 1" pine to make the panel frames & supports.

My problem is that I can't find an insulation material to fill my frames with before I apply the fabric. I am looking for an insulation that is semi-rigid so that the fabric will have a uniform (flat)look. It also needs to be 3/4" thick and preferably be sold in 45-55" wide rolls. Oh, I also want it to be relatively inexpensive (<$150 for approx. 168 sq. ft.)

Am I asking too much? :)

I have found some information on the Owens Corning website. It looks like they have what I need, but their customer service doesn't know where I can buy it. She put me in touch with one of their local reps, but he hasn't returned my call.

I have also found a material called Hushcloth, but it appears to be fairly expensive. ($2-$3 per sq. ft.)

Any suggestions on how to kill the echo without emptying my pocket?

You get bonus points if your answer involves me using the fabric that I have already purchased!

Owens Corning makes a two foot by four foot compressed yellow fiberglass.It comes in thicknesses of two to eight inches.Careful what you wrap it with so it absorbs and does not reflect and not serve the purpose.Go to Jon Risch's web pages and read,read,read then build.Remember:measure twice,cut once.
