INSTALL THE POLYCARBONATE ROOF PANELS
1. Take one 6' x 8' roof panel and remove the protective
film and place a mark on the UV-protected side as a
reminder to install this side toward the sun.
Use assistants when
setting the panels on
the frame. To prevent
interfering with the
installation of the end
panels and flashing, do
not allow the roof panel
to extend more than 1/2"
beyond the end rafter.
3. Set the prepared panel, with its UV-protected side up,
on the hat channel and position the outer edge
no more
than 1/2" beyond the outer edge of the end rafter
.
ATTENTION:
Apply tape
at the upper end of all
upper roof panels and to
both ends of all lower roof
panels to seal the cell
openings.

4. Position the panel square on the hat channel so that
a gap of approximately 1"- 2" remains between the
panels at the top when both panels are installed. Use
the center line on the top of the rafters as a guide to
determine and maintain the gap width.
5. Measure 24" in from the outside edge of the end rafter
and mark the location at each hat channel.
6. Verify that the lower edge of the panel is aligned with
the hat channel attached to the roof frame.
7. Secure the first panel to each run of hat channel using
Tek screws and washers installed through the panel
and into the hat channel at the first set of 24" marks.
(See the black dots for Tek screw locations above.)
NOTE:
Do not install any screws along the edge or
bottom of the panel. Aluminum profile and flashing are
installed later in these areas.
8. Take the first section of 8' H-Channel,
cut it 1" shorter
than the panel length
, and place it along the inside
edge,
flush with the top of the upper panel
.
2. Using the white vent tape, tape the open cells as
described below.

two Tek screws, and secure the H-channel to the hat
channel
near the upper edge of the panel
.
