In panel installations, trim is
typically overlaid on top of the
panel. Special attention needs
to be paid to trim flashing at the
tops of openings. Below is one
method for properly flashing trim in
a panel application:
1) After installing the window, cut
and install a
1
/4-in. thick shim
above the window. The shim
should be the same width as the
trim, and it should be as long as
the width of the window.
2) Over the shim, install flashing
wide enough to cover thickness
of the trim and long enough to
cover the trim head piece.
3) Install the panel to the window
and around the shim taking care
not to damage the flashing and
leaving a
1
/4-in. gap between
the panel and the horizontal part
of the flashing.
4) Install the trim around the win-
dow, slipping the head piece
under the installed flashing.
1 Install
1
/4-in. thick shim
over the window.
2 Install ashing over the
shim and under the water-
resistive barrier.
3 Cut and t panel around the shim and
ashing, Leave
1
/4-in. gap between the
ashing and the upper panel.
4 Install window trim
under the ashing.
