Which would you recommend for exterior insulation in climate 5 Habitat for Humanity home?
I specifically mention Habitat for Humanity, as this means, the work is executed by volunteers and quality control may be an issue. Will the taping and flashing be done exactly right..? Which solution would offer a most “fool-proof” option? I specifically worry about reverse flashing created by somewhat incorrectly installed horizontal tapes. Read couple of articles on that…
So, the house is two story, slab on grade, with most likely vinyl siding. 2×6 construction and OSB sheating, unless we opt for some SIP or other system. I decided that I would not be able to trust ZIP installation. The two high runners right now are 1” polyiso sheets and high density rock wool board. Could someone chime in on pros and cons?
