[Greenbuilding] embodied energy was Polyiso strength on roof

[Frank Tettemer]

I see nothing wrong with using Roxul Comfortboard CIS underthe majority 
ofa concrete slab, while using HI 60 or HI 80 under the load bearing areas.
There really is no excuse to use EPS for insulation in a home, except 
under load bearing areas.

And as for walls ... of course the obvious choice is bales and earthen 
plaster, where appropriate. And where bales and plaster is not 
appropriate, double stud dense pack is always the winner.. (There is no 
reasonable excuse to use foam in walls, either. )

Let's not debate this topic any more, Ergo.
You might as well bite the bullet, as you are preaching to a 
congregation that's been working for years ... decades! ... to find ways 
to safeguard the built environment's  occupants by using natural 
materials.  No one wants to go backwards; you really are not going to 
get any "converts".
