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
: Use three 4' x 12' panels to cover
the area between
same two rafters
.
Complete the steps that follow to install the roof panels.
ATTENTION:
Tek screws (#FA4482) and washers
(#102921) are used to secure all polycarbonate panels to
the framing.
Choose one 12' corrugated polycarbonate panel and
1.
position it between the end rafter and the first interior
rafter. Start the panel an inch
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.)
Place the panel at the desired height above the ground
2.
and on top of the end rafter. Align panel with the center
of the rafter pipe and 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 upper end of the first panel to the
top of the end rafter until the top panel is in position.
Choose another 12' panel and move to the other side
3.
of the frame between
the same rafters
. Attach the
panel as described.
Center the top 4' x 12' panel on the frame and secure
4.
as previously described. Allow the panel to evenly
overlap the upper ends of the two (2) lower panels to
complete the installation of the first set of panels.
NOTE:
To this point, the first run of roof panels (three
panels in all) should be in place and secured to the top
of the end rafter only.
DO NOT INSTALL FASTENERS ALONG THE INSIDE
Use 104709 strips
to seal the panel-to-
baseboard connection.
