The free side of the opening for the operable portion of the window was attached with screws driven through the frame.
A light pencil mark about 1/2 inch up from the unit's bottom helped guide the placement of the flashing and keep it away from the weep holes.
Workers sealed the window to the opening using a tape that repels water and allows vapor to pass through it.
Once the top of the tape was adhered to the window frame, the rest of it was adhered to the dam and to the sill flashing tape.
The jamb flashing was first adhered to the window frame and then extended over to the rough-opening flashing.
