Note! If the existing exterior trim (casing) is to be wrapped with color-
matched aluminum cladding, this cladding MUST be professionally
installed prior to the installation of the clad exterior cover strips. The
following instructions are for a simple butt joint application. A miter
joint application is feasible at the installer’s risk; be sure to allow for a
weep gap.
1. On metal clad
double-hung and
casement windows,
cut and apply clad
exterior cover strips.
a. Measure the
distance between
the existing side
jamb trim pieces
and subtract 1/8".
Cut the head clad
exterior cover
strip to length.
Center and tap
the head strip
into the accessory
groove.
b. Cut two side
jamb clad exterior
cover strips,
leaving a 1/8"
weep gap at the
sill. Tap the strips into the accessory groove.
c. Cut the sill clad exterior cover strip (for Premium windows only,
a 14° sill adaptor may be used in place of cladding strip) to fit
between the two side jamb strips, leaving a 1/16" gap above the
sill. Tap into the accessory groove.
