| Al: welcome to the forums! They are correct in that you will need to install the OSB prior to the siding. If I were doing it, I would pull the windows and doors and reinstall over the osb. Definitely use a metal flashing on top of the windows and doors. I like to use what I call Pella tape (probably comes in other brands) to seal the sides of the windows prior to siding installation. Your tyvek should be wrapped around the openings made by removing your windows, and the windows reinstalled.
The newer poly materials for trim is great. Of course it won't rot, it takes paint just fine and doesn't warp if installed properly. This would eliminate having to wrap the trim with metal. |
