3/4" foam board insulation help
So I just picked up 17k sqft of foam board insulation. It is 200 sheets of 4x21' by 3/4" thick. If I remember right, it is R4.
I'm building a two story and right now I'm framing. I've got 2x6 construction and OSB sheething with house wrap on the outside of that. I was thinking of hanging the foam insulation on the outside of the building vertically. This would allow very few cuts. I was thinking 3 layers and offset the seams so they don't line up.
My question is, what tape do I use on the seams?
What fasteners do I use to fix to the house?
With 2.25" of insulation on the outside, what do I need to do about putting on horizontal siding?
thanks
Austin
