Yeah I know, Mickey Mouse compared to you guys/gals but the plan worked.
The curvature of the ribs easily addressed by thin(er) furring strips, then stacked to get the
depth I desired.
That depth for the second layer of Thinsulate.
OK, 2 x thinsulate not as good as a fat juicy foam board but the she-boss didn't frown at
all about more Thinsulate.
I not only screwed the base furring strip to the rib (thank God I listened to you guys/gals who said
do not put wires in the ribs), then the consequent layers of furring were screwed and glued. Nice
and stout; and the Thinsulate will have a full four inches to expand into.
So I'm typing and Poof is 3M90'ing the second layer into place. Next after a snack the ceiling panel
goes up.

Must be nice to be short enough to have so much insulation! :~(

I used to be 6'1" but gravity has interceded.
The only place where it will be an issue, a place where I suddenly become
penitent is directly under the aircon.
But reality is that we're either driving, sleeping, or out shooting so not
fretting over this even a nit.

Yep, just like laminated ribs in a boat
