Take
polycarbonate
sheet
halves connected
by adhesive tape on
frame from end. Install
polycarbonate
with
outstanding of the edge
out of end plane for 10-
20 mm. If side edge
of polycarbonate are
essentially nonparallel
to frame arcs’ edges, it
means that the frame
is not leveled before
screw tightening and
this operation should
be repeated. Following
sheets of polycarbonate
are prepared in similar
way and installed with
overlapping on previous
sheet for width of arc
profile.
Slide assembled ridge
profile from end side for
11.
For top coverage,
cut 6x2.1 m sheets
in halves per 3x2.1 m
pieces keeping right
angle of cutting line to
sheet side edge. Then
put halves together by
cutting line with aligning
the side edges and
positioning protective
layer outside. Eliminate
mismatch of edges
after cutting halves and
adding them together by
cutting of outstanding
edge. If outstanding
exceeds 5 mm, level both
edges by ruler to provide
right angle of cutting
edge to side edges.

with adhesive tape and
then join the halves with
