Peel & stick – Under or over the strapping
I’m in the process of building a thick foam covered wood framed house.
It’s a 2×6 wall with 2.5″ of XPS, followed with 1.5″ of polyiso foil faced and taped. In order for me to apply my vinyl siding i need to add 1×4 strapping and 2×10 windowbucks as the foam is so thick
I’m uncertain on whether of not to put the peel and stick membane over the 1×4 strapping or under?
My windows are new contruction and have nailing flanges
I have included a picture of what is going on… if i go over the 1×4
you will have to imagine the green membrane under the 1×4 of the other option, but i think you can all see what i’m after.
I was planning caulking the nailing flange and then adding a peel and stick over top of the nailing flage as well
Is this correct?
