Well I got a sudden burst of energy and decided to finish out the pantry.......
I found this in a yard sale 2 weeks ago for 25 bucks

I decided I would place it in the HIH living room and move the plain 45 corner cabinets into the pantry.....

I also finished the floor in there giving a 6.6 R factor to that cold cement floor......

The walls of the pantry were lined with the insulated zip panel also. Where there was a stud I took my table saw and removed the 1" closed cell insulation on the back.

(the table saw came from the same sale for $100.00)
The wall voids were left in tact and I also added 3 layers of 3/4 blue closed cell foam in the stud cavity. This gives the walls in this area just a fuzz under R 18 !
I thought since the remaining walls will probably have open shelves and contain pots pans and other clunky items the fiberglass faced osb would hold up far better than plain ol' drywall.
