Squaring
Before attaching Solexx, it is important to make sure your greenhouse frame is as square as
possible. Do not use the Solexx paneling to square your structure. Solexx rolls may not be
perfectly square.
Expansion and Contraction
We recommend installing Solexx paneling when the temperature is around the average local
annual temperature or a little warmer. If this is not possible, store Solexx in a heated area near
the average annual temperature before it is installed. Solexx will expand and contract as the
temperature changes throughout the day. This expansion and contraction does not impact the
performance of Solexx. By installing Solexx when it is warmer (in an expansion state), you will see
less deflection (waving) in the paneling from rib to rib during the hotter months of the year.
Once it cools off for the day, the paneling will contract and pull itself taut again. Installing Solexx
when it is cooler will not affect the performance of the material, but you will see more deflection
(waving) in the paneling from rib to rib due to the expansion of Solexx. From our experience, you
do not need to predrill holes like you do when installing polycarbonate.
Attaching Screws
Commercial installation of Solexx involves the overlapping of one panel with another panel. That
is why our panels and rolls are slightly wider than standard 4’ (1.21m), 5’ (1.52m) or 6’ (1.83m)
greenhouse panels. This allows for variances in the on-center spacing of the support poles and
the creation of a good seal between the panels. The screws are attached directly through the
panel and into the framing. If you are installing Solexx over a polycarbonate metal frame, you
can screw the paneling directly onto the existing frame. A self-drilling screw with a neoprene
washer is recommended when attaching Solexx paneling to metal framing. For wooden
structures, a wood screw with a neoprene washer is recommended. To conform to the
requirements outlined in the Solexx warranty, usage of a neoprene washer screw is required for
all installations. Any use of a non-neoprene washer screw, nail or large metal washer will void
the warranty.
Where Solexx overlaps on the frame and on the outer edges of the panel, attach a screw every
4” – 6” (10-15cm), do not caulk between the layers. Attach screws into any additional framing
support every 12” (30cm) if you desire. Be careful not to over-torque the screws, or you may
crush the paneling; the washers should just slightly dimple the paneling. You may want to drill
pilot holes into a metal frame to prevent damage to the paneling if the screw slips.
Cutting Solexx
It is helpful to attach the panel to your structure first before you cut, and then use a sharp, thin
utility knife to follow the frame as a cutting guide. Our experience has found a flip-back utility
knife works best. This type of knife cuts Solexx cleanly due to the way the blade is held by the
knife. We recommend cutting the panel with two passes of the knife and using a straight edge to
ensure straightness of your cut.
