Window flashing before or after housewrap
DuPont has two different manuels for flashing windows. I think the more common way is to install and flash the windows after the housewrap. Is that the best way though? What happens if water gets behind the housewrap? Would it not make more sense to install and flash the windows to the sheathing, then install the housewrap over that?
my sheathing is plywood. I plan on taping the joints. Windows have a nailing fin. Sheathing will be covered with Tyvek, rain screen and hardie siding.
