I am in northern Minnesota . I was going to do a SIPS house but live where labor is cheap.
Yet... I don't want to do stick...it's a cabin and the mice will infest it....bats will get into the crawl space.
So..since my local store built his own walk in cooler using thick EPS from Home Depot... I figured I'd put up a slab..use 2x4 versus
2x6...12? inches set back from edge and glue EPS on the stick frame..leaving 3 1/2" for wiring, plumbing, ducting etc. And put plastic then gypsum board on the inside of the 2x4 sticks. When I pour the floor I will also do a "strom closed...6x10 walk in... Iam in tornado country. Then I would glue ext plywood or est strand board over the EPS outside like the laminators and side it or elastomeric stucco it.Oh... I will have to pay for a SIPS roof or..maybe I will put trusses in ..put moisture sheet over that, then EXT plywood then glue 6" EPS then more plywood then steel roof.
What do you think?
