Just received a quote for roof insulation with closed cell foam between
the rafters. The quote is for 3" and I am being told that 3" is 90% as
good as 6". Do I believe them?


That kind of stuff makes me paranoid. Foam just seems way too flammable a
material to entombing your home with.



Foam is treated to make it self extinguishing. It will not burn unless
something next to it is burning. Code requires it to be covered with
sheetrock if exposed to the living space.
