According to Larry Fishel :
how are you insulating the roof?

Fiberglass batting unless someone else has a better idea. I now see
that Owens-Corning makes a rigid fiberglass board that is slightly
better (R-15 vs R-13 for 3 1/2") but it's way more expensive and I
don't know enough about the subject to know whether that's a significnt
difference. I think I've worked with the foam board that m Ransley
mentioned and found by experiment that it burns like a sparkler if you
get it started.

rockwool batts (eg: Roxul) have about R15 for 3 1/2", and usually
don't cost any more than fiberglass. A lot easier/nicer to install
too.

But is it actually for sale anywhere?
