Installation Guide

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 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 window,
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.
