Finally, the exterior foam work has begun. Rigid closed cell foil faced foam (called Iko Enerfoil) arrived the 1st week of April and Scott's crew has moved quickly to begin the process of attaching the foam to the house.
Virtually all the shingles have been stripped and 2 layers of foam have been installed, with the seams taped and each layer staggered to ensure a more effective air barrier.
Remaining is some of the detailed air sealing work that will need to fill in all the gaps by the windows, doors, at the bottom and top of the foam. Scott Sorensen (contractor) and Olaf Vollertsent (architect) have had many conversations about where to spray foam, how to seal the foam at the corners, what screws to use to attach the foam and then the strapping, etc. etc. Complicated stuff but necessary.
