How do you strengthen glass?

Laminating glass: Demand and quality perfectly combined

sedak glass laminates are created by connecting two or more panes of glass using elastic, tear-resistant films made of polyvinyl butyral (PVB), SentryGlas® (SG), ethylene vinyl acetate (EVA) or special films such as TPU. sedak laminated safety glass (VSG) reduces the risk of cuts or stab wounds in the event of glass breakage, strengthens the residual load-bearing capacity of the glass composite and has a sound and heat insulating effect.

Air out, perfection in: glass lamination in a vacuum.

Laminating glass without air pockets, sedak produces the pre-lamination under clean room conditions and using a vacuum process. In autoclaves, double or multiple laminates fuse to form an inseparable unit.

sedak VSG can also be made from thermally bent glass panes. Even during the lamination process in the autoclave, panes can be bent using so-called lamination bending.

The composite properties of sedak VSG in conjunction with SentryGlas® film set standards: they almost correspond to monolithic glass of the same thickness. There is an extremely high level of adhesion and bond strength between the film and the glass. sedak VSG with SentryGlas® film has an optimized post-breakage behavior. It is preferably used as a facade element, for overhead glazing, as safety glass or for special constructions such as all-glass stairs.

Through the special treatment of the edges during lamination, we give them an excellent quality. This is both functionally and visually a significant advantage for the exposed, especially for the weathered glass edge. In this way, it is able to carry away significantly higher and permanent loads.

Innovative sedak glass products with SentryGlas® film.

In order to improve the rigidity and load-bearing capacity of glass constructions, sedak has long been using and perfecting the special bonding properties of SentryGlas® film (SG) in the lamination process. The groundbreaking result of this commitment: a glass refinement product that bears the brand name GlasCobond® in the architectural sector and the name GLY-MarineCobond® in the marine sector.

Both are registered trademarks and are manufactured and distributed by sedak. Only lamination with SG film enables glass bridges, glass stairs, glass roofs and glass floors with surprisingly little supporting structure.

The experience gained, the sedak production technology and the quality awareness in SG lamination also benefit the processing of PVB, EVA and TPU laminates and all other interlayers.

Special laminations and laminated connecting elements.

Intensive sedak research and development make it possible: a wide variety of materials can be laminated between two panes of glass. For example sheet metal, stone slabs, projection films and other materials. They expand the scope for design and give the glass laminate a unique look. Innovative sun protection options can also be firmly integrated in the glass composite. In addition, sedak can laminate glass and laminate a wide variety of connecting elements. Be it in facade panes, glass swords, horizontal glazing or other elements up to 3.6m x 20m.

Laminating materials has a number of advantages. This includes not only protection against environmental influences such as rain or sandstorms, but also considerably easier and more thorough cleaning. The quality of the product is preserved and its lifespan is significantly extended. How diverse we are when we laminate glass can be seen from these application examples:

sedak lamination competence

Ready for assembly ex works: lamination or bonding of metal parts to the glass.

With the sedak lamination process, it is possible to attach fastening parts such as handrails directly in the factory. It is also possible to glue metal parts to the glass. Invisible and highly precisely positioned, they significantly simplify on-site assembly.

If seals or bonds are made on the construction site, visible bubbles often appear. sedak, on the other hand, already applies a special filler layer to all types of sealing. This process is of particular interest where the back of the seal is visible through thick glass structures.
