Insulation refit and balancing the insulation.
House located in zone 2A, off the ground ~ 2 feet (1800 sq ft). The house has a sloped metal roof with 2 x 6 rafters on 24 inch centers and 2 x 4 stud walls on 16 inch centers. Currently there is no insulation in the walls or floor and 5 1/2 inches of fiberglass on the attic floor.
Attic Unvented (~R30) 5 1/2 inch fiberglass batt with 2 inches of rigid poly iso foam.
Walls (~R20) 3 1/2 inch fiberglass batt with 1 1/2 inches of rigid poly iso foam.
Floor (~(R13) 2 inches of closed cell foam.
Windows triple pane low e argon gas filled.
Is this a balanced insulation plan? I am looking for the most bang for my buck and was wondering if these insulation levels made sense together?
