This 12-step face-sealed window installation series shows the sequence for a properly weatherlapped installation of the window unit but not the rough opening. A face-sealed installation like this is appropriate for low to moderate weather exposure. This installation series is also for the window unit going in before the weather-resistive barrier (building paper or housewrap).

Details that show the complete and final configuration of window installations are fine, but window installation step-by-step series are where the rubber meets the road.
