I was quoted $3.45 sq ft for the 2 x 4, R26 panels and $4.98 sq ft for the 2 x 6, R42 panels. Panels are 8, 9, 10, & 12 ft long. Shipping is $500 to $1100 from Idaho. These are the contractor builder prices. The foil on both sides is supposed to minimize reductions in R value. You can router channels for wiring and refill the foam and foil tape, but I plan to do a electrical raceway built into the baseboard. Labor is probably more but my time, since I am retired, doesn't really add up too fast. Crane cost for the sips is eliminated.
