INSTALL WINDOW
WARNING! To avoid injury, use at least two people to install.
Adequately support the window until completely fastened.
1. Run a continuous 3/8"
bead of sealant around
the interior side of the nail
fin on the side jambs and
head. On the sill, leave at
least a 2" gap every 8"
where it will contact the
rough opening.
2. Place window onto the
shimming support and tilt
into the rough opening.
The window sill must rest
on and be fully supported
by the shimming support.
3. Fasten window through
the nailing fin between
3"- 7" from one upper
corner.
4. Shim at each interlock, or
in the center, and within
4"- 6" of each corner on
the side and head jambs.
Apply additional shims to
the side and head jambs
as necessary to ensure
window position within
the opening is plumb,
level, and square. Larger
windows usually need
additional shims. Shims can
be secured with sealant or
adhesive.
5. Inspect window for square,
level, and plumb. Test for
proper operation (remove
and reinstall if necessary).
