Installation Instructions
for Vinyl Windows without Nailing Fin (JII011)
4. Inspect the window for square, level, plumb and twist (Reference
the Product Installation Tolerance Table).
5. Repeat the steps above for each installation clip.
6. For products with a rating of PG 50 refer to “Special Fastening
Requirements”. Install clips are not meant to be used on WZ3-
Impact product.
7. Once the window is secured proceed to Section 6 – Install Drip Cap
C.) STOP-IN METHOD
NOTE: This method is typically used in a “pocket” style installation where
a vinyl window is set into an existing window frame that has a sloped sill.
The existing opening should be sound and weather tight prior to installing
the vinyl window.
Exclusions: This install method excludes windows with pre-applied
extension jambs and impact units.
1. Make sure the sloped sill
adapter has been installed
onto the window.
5. Along each side apply a shim 4"- 6" from each corner and in the
middle of the window frame (shims should be cut 1/4" - 1/2" back
from the interior face of the window frame). NOTE: Some hung
windows have a “jamb jack” along each side. Engage the #8 x 2" at
head screws until the rst click is heard and then adjust the jamb jack
as needed prior to adding shims.
6. Apply additional shims to the side and head jambs as necessary to
ensure window position within the opening is plumb, level, square
and without twist. Larger windows usually need additional shims.
Shims can be secured with sealant or adhesive (Reference the
Product Installation Tolerance Table).
7. Apply head expander if needed. Insulating material may be placed
atop of the window frame prior.
8. Create a continuous interior
air seal by applying lower
expansion polyurethane foam
or backer rod and sealant
between the newly installed
window frame and existing
opening. The depth of the
air seal should be
approximately 1/2".
9. Apply interior and secure
stops to all four sides of the
opening. Stops should overlap
the interior face of the frame
by a minimum of 1/8".
10. Refer to Section 7 – After Installation for relevant information.

2. The opening should be
prepped so that only the
exterior stops are in place.
Make sure stops are of an
adequate size so they will
overlap the exterior face of
the frame by a minimum
of 1/8" on both sides and
the head. NOTE: If a stop
is present along the bottom
make sure this will not block
drainage from the weep
holes or from under the
sloped sill adapter.
3. Apply sealant to the interior
face of the side and
head stops.
4. Set the window into the
opening so the exterior face
of the frame makes full contact with the sealant
and stops.
