SEDAK: BIG IN DETAIL

By firing the colours in the
tempering furnace, they are
permanently bonded to the
surface and the print is ex-
tremely resistant. The glass
produced for BAU 2017
was printed with a photo
showing how an insulating
glass unit is siliconized on
the world’s largest insu-
lating glass line in sedak’s
production hall.
CURVED
WITH PRECISION
Cold-bending during lami-
nation enables sedak to
produce curved glass of
very high quality. Dur-
ing the lamination process
in the autoclave, only the
foils between the glass lay-
ers melt. After cooling, the
glass therefore appears
in perfect quality without
any roller waves or other
defects.
Cold-bent multiple lami-
nates redefine the possi-
bilities of glass processing.
The fabrication requires an
absolute precision and di-
mensional accuracy. sedak
presented a 20 millime-
tre thick triple laminate of
1.28 by 3.68 metre sam-
ples similar to the model
that had been installed on
a mega yacht. The bending
line with a rise of 120 mil-
limetres is diagonal so the
glass pane nestles perfectly
against the ship’s spheri-
cally shaped hull. Beside
the high demand for preci-
sion, the glass panes have
to pass leak tests for usage
under water. But the archi-
tectural sector also benefits
from cold-bent glass since
