I was discussing upgrade options with my GC and the insulation contractor. We talked about the pay back on spray foam insulation. The insulation contractor suggested I would see a better payback using 1/2 energy shield insulation board on all of the exterior walls.This would be in addition to 5 1/2 inches of R-21 Unfaced Fiberglass Batt Insulation.Does anyone have experience or thoughts on using insulation board on exterior walls.It seems like a pretty good option versus 2 of R-13.6 closed cell spray and 3 1/2 inches of R-11 unfaced fiberglass batt. The closed cell option is a $4500 adder.The house is in New Hampshire, so we have some pretty cold winters.he insulation contractor suggested I would see a better payback using 1/2 energy shield insulation board on all of the exterior walls.
