Have others used 1" or 1.5" HVAC rigid ductboard a substitute for 703/705 insulation with much success? I have used it in my personal studio designs due to a cost factor, as it is also compressed insulation, but am asking for professional opinions based on personal experience with both.
Thanks.

Haven't actually used it as yet, but spec-wise I saw a couple of versions that are virtually identical to 703/705, except better because the surface is more durable. I'm not sure what the different surface does to grazing incidence (as compared to straight on, 90 degree incidence)
Anybody else?
Soooo, when a Musician dies, do they hear the white noise at the end of the tunnel??!? Hmmmm...
