INSTALL CORRUGATED ROOF PANELS (continued)
6. Repeat the steps to install the lower two 4' x 8' panels
between the same two rafters for the other side of the
frame.
When attached, an opening at the top of the frame
between these two rafters will remain. Cover this
opening using a single 4' x 12' panel.
7. Center the top 4' x 12' panel on the frame and secure
as previously described. Allow the panel to overlap
the upper edges of the lower panels to complete the
installation of the first set of panels.
NOTE:
To this point, the first run of roof panels (5
panels in all) should be in place and secured to the top
of the end rafter only.
NO FASTENERS ARE INSTALLED ALONG THE
INSIDE EDGE OF ANY PANEL. THE NEXT SET OF
PANELS MUST OVERLAP THIS EDGE BEFORE
SCREWS AND WASHERS ARE INSTALLED.
See dashed line and arrows below.
8. Return to the first seam where two panels overlap and
cut a section of poly-latch U-Channel (#102197) so that
it fits between the rafters.
NOTE:
Position the channel at the seam
on the inside
of the greenhouse roof where panels overlap
. Install
Tek screws (#FA4482B) and washers from the outside,
through the two polycarbonate panels (where they
overlap), and into the poly-latch U-Channel to secure
the seam.
Install screws in the valleys of the panels.
Secure
all overlap seams as you work toward the other
end of the greenhouse
.
Use 4 Tek screws (#FA4482B) and 4 washers for each
seam to secure the roof panels to the U-Channel.
9. Once the seams for the first run of roof panels are
secured, install the next run of roof panels.
ATTENTION:
These panels will overlap the edges
of the installed panels and are secured to the rafter
common to the first set of panels. This is the pattern
throughout the length of the frame.
To more easily reach the rafter to secure this next run
of polycarbonate panels, roll the panel under or over
itself during the installation and unroll the sheet after
securing the edge to the rafter.
Install the horizontal closure strip (104709) between
the panel bottom and the baseboard and continue as
previously described.
