Glasstec 2016: sedak Presents Curved Multiple Laminate at glass technology live

Cold Bent During Lamination - Glass Laminates for Shipbuilding

Extremely heavy, extremely thick and processed with an extreme precision - with its multiple, elliptical laminates cold bent during lamination, sedak (Germany) shows, what can be done with glass. At the special show "glass technology live", the leading fabricator of (functional) glass in maximum formats up to 3.2m x 16m, presents a triple laminate. The glass expert shows a pioneering solution that opens new possibilities also for the shipbuilding sector.

The exhibit exemplarily 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 the shipbuilding industry.

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.

"glass technology live" is a joint exhibition of 30 participants under the leadership of the University of Stuttgart (graduated engineer and architect Stefan Robanus). It takes place from 20th to 23rd September 2016 in Düsseldorf within the scope of glasstec. (hall 11/ D42)
