INSTALL THE CORRUGATED ROOF PANELS
The corrugated roof panels are attached to the tops of each
rafter using Tek screws and washers. These panels are
designed to span the 48" on-center rafter spacing, which
allows each panel to overlap the previous panel.
CONSULT THE MAIN COVER DETAILS DIAGRAM IN
THE QUICK START SECTION OF THIS DOCUMENT
FOR ROOF PANEL INSTALLATION DETAILS.
Panels are installed beginning at one end of the
greenhouse and working toward the other end. All panels
are installed between two rafters and over the greenhouse.
The overlap seams are secured before moving to the next
rafter.
REQUIRED PANELS (5)
: Four 4' x 8' panels are used to
cover the lower sections between the rafters—two panels
on each side. The single 4' x 12' panel is used to cover the
top section between the
same two rafters
.
Complete the steps that follow to install the roof panels.
ATTENTION:
Tek screws (#FA4482B) and washers
(#102921) are used to secure all polycarbonate panels to
the framing.
1. Choose one 8' corrugated polycarbonate panel and
position it between the end rafter and the first interior
rafter. Start the panel an inch or so
above
the lower
edge of the baseboard as shown below.
NOTE:
Install a section of the 104709 horizontal
closure strip under the edge of the panel
before
attaching the panel to the rafters. See the arrow above.
The horizontal closure strip (104709) can also be
installed flush with the top of the baseboard to prevent
dirt and debris from filling the spaces between the
polycarbonate and the baseboard. (See the dashed
line in the photo above.)
2. Place the panel at the desired height above the ground
and on top of the end rafter. Align panel with the center
of the rafter pipe.
3. Attach the panel to the
top of the end rafter
and to the
baseboard.
ATTENTION:
Install Tek screws and washers at 16"
intervals along the panel edges for all roof panels. The
lower and upper ends where different panels overlap
are secured every 12". Be sure to
position the panel so
that it reaches the second rafter.
DO NOT
attach the first panel to the second rafter at
this time.
Attach it to the end rafter only
.
The next panel will overlap the previous panel, which is
the repeated pattern for the length of the greenhouse.
DO NOT
secure the end of the first panel to the top of
the end rafter until the next panel is in position.
4. Choose another 8' panel and align it with the center of
the end rafter as described Step 2.
5. Position this second panel so that it overlaps the top
edge of the first panel
no more than 2 inches
, and
fasten the panel in place.
Panels are not to scale. Drawing is used for illustration
purposes only.
Use 104709 closure
strip for the baseboard
and panel connection.
