On wood framed structures I’m a fan of conventional schemes.
I don't know much about the foam, but I do know a good bit about conventional in areas where it really matters.
I am gonna have to watch some of these newer homes getting all foam or "air tight" insulation jobs.
I see them going up but never paid much attention.
I do know I can tell a lot about a homes insulation when there is snow and or ice on the roof.
It's kinda a tell tell sign of just how well the insulation job went, especially soffit and baffle work.
I can see what they are after in the illustration but not so sure I want to heat and cool all that attic space to achieve it.
