Are you planning to line the interior?
The reason I ask is my 48 x 60 is going up next week.

Every inch of foam is r7, and they recommended 2”. However, my construction buddy told me you can’t compare R to R since this stuff is closed cell and it seals. 2” inch of this (r14) is better insulation than an R38 blown in. I can’t say for sure. I do know it increases the structural integrity of the building tremendously and helps a lot with sound dampening. I am putting metal up inside as well. They make an FJ channel that accepts the ceiling panel and wall liner. As far as cost I didn’t price batts, but this is expensive. The walls were $4,000. To line the gable and roof to complete it seal the building is an extra $5,000. I’m undecided on the ceiling/roof insulation yet. The budget appears to be breaking.
