sedak will present a triple laminate at glass technology live during glasstec
Extremely heavy,
extremely thick and processed with an extreme precision – with its
multiple, elliptical laminates cold bent during lamination, sedak
shows what can be done with glass. At the special show “glass
technology live” during glasstec, the leading fabricator of
(functional) glass in maximum formats up to 3.2m x 16m, is presenting
a triple laminate. The glass expert will show a pioneering solution
that opens new possibilities also for the shipbuilding sector.
The exhibit shows a
20mm thick triple laminate in the dimensions of 1.3m x 3.7m in a way
it has already been installed in a yacht’s hull. The glass pane was
cold bent during lamination with a rise of 120mm and a diagonal
bending line. It therefore nestles perfectly against the ship’s
spherically shaped hull. The edge has been ceramic-ink printed to
protect the bonding against UV radiation and to ensure a flawless
visual quality. “Besides this glass pane, 39 elliptical glass
laminates with 15 different bending radii were installed in the mega
yacht,” says Ralf Scheurer, project manager at sedak. The single
laminates have a weight between 85kg (double laminates) and 1,250kg
(10-layer laminates). The latter ones are 12.8cm thick and were
installed in the yacht’s lower bow. Despite different dimensions,
each of the 40 glass panes has an area of about 4.0sqm.
The 10-layer
laminate passed the required leak test 50m under water (load
pressure: 50t/m²). The glass has been registered as a trademark for

This cold bending
technique has been optimized by sedak. Prior to lamination, the glass
lay-up is bent to the required shape on a bending rig. Afterwards,
the lay-up is bonded together in the autoclave.
That process
requires clean-room conditions under which the fully tempered or
heat-strengthened glass panes are assembled to form the laminate. In
order to avoid air bubbles and to ensure a high-quality product, the
glass lay-up is laminated in a vacuum bag.
sedak uses a
shear-stiff SentryGlas® interlayer so that the glass maintains its
curved shape after the lamination process in the autoclave.
The advantage of
cold bending during lamination: no surface deformation and therefore
the best visual quality that a bent glass can offer.
sedak
supplies monolithic glass, multi-layer glass units, and functional
insulating glass in dimensions up to 3.2m x 16m: processed, tempered,
laminated, printed, coated, and cold bent. The manufacture of glass
up to 15m is fully automated thanks to the world’s largest
insulating glass line.
