How to install windows if I build with 2″ rigid foam?
Hi. I live in zone 5. I want to build my house not only with 2 x 6 stud walls for extra insulation but also with 2″ of rigid foam as that is what the article I read said I would need so I don’t have a cold wall.
I do not think I want to have the rigid foam next to my house sheathing so I want to put the house wrap my lumber yard sells over the sheathing like normal before the rigid foam covers it. So I am wondering, should I install the house wrap like normal homes do and then build a 2.75″ deep x 2″ wide frame around the window opening nailed through the house wrap, osb, and trimmer stud so my window is on the same plane as my siding?
If this is the best option, what will I do to flash the window or the opening since it is built out?
