The fact is, they couldn't and can't, and rather than lie to consumers (just to sell this product at a higher cost) Owens Corning have done the right thing and published reliable testing"
I have no idea where he got that from, but I'd love to hear more if he can back it up. In particular, I'd like to know how Joel seems able to read their mind, know their motives, and so forth. Joel, did you get that from someone at Owens-Corning? If so, who? I'd like to call them up and dig deeper into this.

My understanding is all of these products are used for insulation in structures (buildings, ships and so on) and acoustics is just a minor fraction of there sales. We all just got lucky we have it to use.

Exactly. Acoustics is a tiny part of the market for rigid fiberglass. It just works out well for guys like you and me that the same material can be used as the basis of bass traps and absorber panels.
