sedak knowhow in incomparable quality

Glass lamination: the perfect combination of aspirations and quality

Only a few companies in the world can perform glass lamination as perfectly as sedak, including oversize formats.

Laminated glass from sedak is produced by bonding together two or more panes of glass with elastic, tear-resistant sheets of polyvinyl butyral (PVB), SentryGlas® (SG) or ethylene vinyl acetate (EVA). Laminated safety glass from sedak reduces the risk of injuries upon breakage of the glass, increases the residual loadbearing capacity of the laminated pane, and also insulates.

Air out, perfection in: laminating glass in a vacuum

In order to exclude air inclusions during lamination, sedak prepares the glass/interlayer composite in clean-room conditions using a vacuum method. Autoclaves then bond double and multiple laminates into one permanent unit.

sedak laminated safety glass can also be produced from hot-bent panes, and we can also bend panes in the autoclave during the laminating procedure using the cold-bending process.

The composite properties of sedak laminated safety glass set standards; they are more or less the equivalent of a monolithic pane of the same thickness. Laminated safety glass from sedak exhibits an enormous adhesion and bond strength between the interlayer and the glass. sedak laminated safety glass with SentryGlas® interlayer has an optimized post-failure behavior. It is especially used as a façade element or safety glass, for overhead glazing or special constructions like e.g. all-glass staircases. Laminated safety glass is preferably used in facade elements, for overhead glazing, for building thicker glass units or for safety glazing.

The special treatment of the edges during lamination results in edges with an outstanding finish. Our edging has huge functional and visual benefits, especially for edges exposed to the weather, and helps edges to withstand much higher, permanent loads.

Innovative sedak glass products with SentryGlas® interlayer

For improved stiffness and load-carrying capacity of glass structures, sedak has been using and perfecting the special bonding properties of SentryGlas® sheets in the laminating process for a long time. The groundbreaking outcome of this commitment is a glass product marketed under the names GlasCobond® for architectural applications and GLY-MarineCobond® for nautical projects. Both products are registered sedak brands produced and marketed exclusively by sedak.

Only through laminating with SG sheets is it possible to build bridges, stairs, roofs, and floors in glass with amazingly few structural members.

Our acquired experience, sedak’s production technology, and the awareness of quality demands in SG laminating have benefited processing of PVB, EVA, and TPU laminates and all other interlayer materials.

Special laminations and connectors laminated between the plies

Intensive sedak R&D makes it possible to laminate the most diverse materials between the plies of glass, e.g., sheet metal, paving stones, projector screens, etc., thus expanding design options and lending a unique appearance to glass laminates. Innovative solar control options can also be permanently integrated into the laminated glass.

sedak can likewise laminate the most diverse connectors and fasteners between the panes of glass for facade glazing, glass fins, floors or other elements in sizes of up to 3.6m x 20m (138in x 787in).

Laminating material in between glass layers offers several benefits. That includes not only the protection from environmental influences like rain or sandstorms but also a considerably easier and more thorough cleaning. Thus, the product's quality is preserved and its lifetime significantly lengthened.


Ready to install ex works: metal components bonded to the glass

The sedak laminating process makes it possible to bond fasteners like e.g. handrails directly at the factory. Bonding metal elements to glass is also possible. We position fasteners invisibly and accurately, which significantly simplifies erection on site.

Performing sealing jobs on site often results in ugly bubbles. As a solution to this problem, sedak applies all types of sealing material at the factory to achieve a blister-free finish. This method is especially advantageous whenever the back of the sealing is visible through thick glass.
