IMPORTANT
:
Under no circumstances should a
support structure allow force or weight to be applied to
polycarbonate panels! Supports must span from rafter
to rafter when used. Consult a contractor if needed for
additional information. Take additional steps to protect
polycarbonate panel surface.
Use of a lift is strongly
recommended.
If bracing and U-channel trim were installed during
panel installation, skip this section and continue with the
installation of baseboards.
