Paul Mallory Owner-Builder Support Project - Santa Fe, NM
After lots of deliberation I chose to insulate the exterior of the house with 2” rigid foam boards. I couldn’t find mineral wool boards that weren’t almost three times the cost and months out on delivery. It was unfortunate, but I wanted my project to continue to move forward and not be held up waiting for deliveries. I attached the insulation with 5” spiralized nails with a head. The 4” weren’t deep enough.
