5
WARNING! To avoid injury, use at least two people to install.
Adequately support the window until completely fastened.
Areas such as Florida and the Texas TDI region have different
anchoring requirements based on product certification. For
information on specific products, visit www.floridabuilding.org
or www.tdi.texas.gov and follow the anchoring schedule given in
the drawings for the product instead of the anchoring schedule in
thisdocument.
Note! Fastener (anchor) heads must be flush. Do not dent nailing fin.
1. Run a continuous 3/8"
bead of sealant around
the interior side of the nail
fin/trim 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 n/trim
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).
