High Security Building Envelopes from a Single Source

Specifying high security façade systems, doors and windows just got easier. Sälzer GmbH has been specialising in innovative high security systems for over 50 years and became part of the Schüco family in 2018.


The Sälzer range has now been fully integrated into the Schüco product catalogue enabling high security requirements to be fulfilled from a single source, even in modern building envelopes with large expanses of glass.

What sets the Sälzer suite of products apart is the fact that multiple security requirements can be combined in the same system. A highly burglar-resistant façade, for example, can be built to be bullet or blast-resistant in some areas, or it can provide equal protection against all three threats.

Not only does the system allow different requirements to be met but there are no sight-line differences when transitioning between the high blast resistance façade to low blast resistance facades. What’s more, the high-security façade can be seamlessly combined with a section of façade that does not provide any protection.

This uniform design has been achieved through the close collaboration of the two building envelope specialists from the planning and development stages. The S1es-50/S1es-60 high-security façade was based on the Schüco FWS 50/60 (Façade Wall System, 50/60 mm face width) mullion/transom façade.

All Sälzer designs are thoroughly tested and certified by independent institutes, often far beyond the standard requirements.

The S1es-50/S1es-60 high-security façade system offers burglar resistance up to resistance class RC 5 as well as bullet resistance up to FB7. It can also withstand a blast test with 500 kg of explosives. As a result, the high-security façade offers a high degree of resistance to burglars armed with heavy equipment and assailants with long firearms, as well as terrorist attacks.

The high-security system is complemented by a wide range of tested and certified high-security Sälzer doors and windows. A variety of design options is available including dual colour systems, outward opening and motorised options, and high security sliding doors.

Look no further when designing a building envelope that requires the comprehensive protection provided by Sälzer’s high security system range and the design quality, precision engineering and technical advice for which Schüco is renowned.
