I have direct experience with several types of insulation, having paid 
to have them installed in buildings on my property. I will try to post
some useful feedback asap. Basically it consists of a list of preferred 
types of material:
1) nontoxic, nonflammable, waterproof, UVresistant, hard setting i.e. 
structural Spray-On Foam Insulation: Icynene and Demilec are two brands 
I am familiar with.
2) Rigid foam board insulating panels, nontoxic, nonflammable,
in pressure strengths of 150psi to 600 psi. Brands include: CavityMate 
(blue) and Foamular (pink) from Dow, Corning, DuPont(?). Available sizes 
nclude 2'X8' and 4' scred)X8'
3) AAC Block, aerated, autoclaved concrete block. Brands include: Hebel 
and Aercon. Sizes and strengths: many sizes of panels, steel reinforced 
and blocks, different widths and lengths for load-bearing (with steel 
reinforced poured concrete beam as top course on walls) and non 
load-bearing walls (i.e. as cavity wall insulation, Ex.: between
exterior and interior load-bearing concrete block or brick walls.

I have used 1), 2) & 3).
