b. If installing a
window with
fasteners through
the jambs,
secure with a #8
screw until fully
seated (without
deforming vinyl).

window using the
stop in method, this
installation assumes
installation from the
interior with exterior
stops applied before
window installation.

frame by a minimum
of 1/8".

exterior stops and verify it is properly shimmed until square, level,
and plumb.
c. Apply backer rod and sealant or low expansion foam on the
interior between the window frame and rough opening on all
four sides.
d. Install interior stops on all four sides.
4. Inspect window for square, level and plumb (adjust shims or remove
and reinstall if necessary).
5. Fasten window in a similar manner through the remaining corners,
and then through the rest of the fastener locations. If installing
fasteners in the sill, apply silicone sealant to the screw threads and
the head of the screw in the window frame (use more sealant as
necessary to completely seal the screw head to the frame), or use a
gasketed head screw.
6. Insert plugs into fastener holes not located in any operating track.
Seal plugs in the sill with silicone. Replace track fillers if applicable.
7. On some double
hung operating units

hardware is mounted

adjustment. Install
jamb adjuster screws
until captured (first
‘click’), the screw
may then be screwed
in or out to adjust
the jamb as needed.
Replace lower sash.

expander (optional)
over the head of the
window as shown.

apply sealant to
the inside edge of
the outside stop.
Set window with
a sill adapter fully
against the outside
stop. Continue with
“All Installations.”
