I saw in the other foam post, a link to the Johns Manville product, Spin-Glas Board. I followed the link and nosed around the J-M site.
I'm curious as to the general consensus regarding another J-M product, Whipertone Wallboard.

The JM copy indicates the Spin-Glas product provides "good acoustical performance" while the Whispertone exhibits "excellent acoustical performance".
Thoughts?
