Laminated safety glass
for new options in glass construction.



The laminated safety glass SIGLAPLUS® is a so-called glass sandwich allowing the use of glass in large dimensions. Both technically and aesthetically it meets the high demands which today are placed on innovative glass construction. SIGLAPLUS® is certified according to DIN EN 14449 and has the General Construction Approval Z-70.3-253 enclosure 1.

SIGLAPLUS® consists of two glass panes fixed together by means of a strong interlayer. To do so the experts at FLACHGLAS Wernberg make use of a specially developed procedure. Numerous tests have proven SIGLAPLUS®’ excellent quality regarding residual strength, edge stability and thermal resistance.

Another advantage: SIGLAPLUS® offers a variety of installation options. For fixation to the substructure, our stainless-steel holders for point-fixed glass units are the perfect solution.


The variant SIGLAPLUS® S is our laminated safety glass with shear bond. In order to be able to optimally guarantee its special quality it is subjected to additional in- and external tests. Regarding its production as well as its physical, chemical and mechanical qualities it equates the high standards of SIGLAPLUS®.

With SIGLAPLUS® S, a positive shear bond between the individual panes may be statically applied on the basis of the general type approval Z-70.3-253 Annex 2. This benefit allows for a reduction of the glass panes’ thickness of up to 30 percent without impacting the excellent structural properties and the attested stability of SIGLAPLUS®.

Due to weather-related loads such as wind or snow as well as live loads caused by people the shear bond between the single panes may vary. Within certain limits SIGLAPLUS® S allows to take this shear bond into account.


Both variants of our laminated safety glass are also available as UV-permeable alternative SIGLAPLUS® UV. It is used in botanical gardens, vivariums and winter gardens, for example.

All details at a glance.
