Cut to
Exact Length
Tab
Measure the required dimensions to
cover window trim. Also, determine
the required lengths of trims.
Cut trim sheet to the measurements
and form each sheet on a bending
break. (Fig. 1)
Trim sheet should be installed in the
following order: bottom, sides, top.
Place the trim sheet on the window
frame and mark it for cutting.
Create tabs into the trim sheet (both
ends of bottom piece and tops of both
side pieces) so that it covers the edge
areas.
Miter the bottom of the side pieces
and both ends of the top piece. (Fig. 2)
Nail into place using painted aluminum
or stainless steel trim nails. Pre drill
nail holes and do not nail tight. The
top piece should be the last section to
be nailed into place. (Fig. 3)
NOTE: Dissimilar Materials:
Direct contact of aluminum products
with certain dissimilar materials,
or contact with water run-off from
dissimilar materials, is likely to
result in corrosion. Accordingly, care
should be taken during installation
to avoid such contact of aluminum
with dissimilar materials including
dissimilar metals (e.g. copper, zinc,
steel, etc.), concrete, stucco, asbestos
siding, pressure treated/pretreated
lumber, masonry, roofing materials or
roofing systems containing metallic
granules or strips, or corrosive non-
metallic materials.
A barrier must be used to separate
trim from any pre-treated lumber.
Optional barriers include: plastic,
house wrap, roofing felt, foam, or a
high quality primer or paint.
