Safety glass

Glass is not just a transparent material that creates brightness and a feeling of spaciousness. In fact, through special refining and machining processes, glass can also perform protective functions in a variety of ways. That is why our safety glazing product range includes our thermally toughened and laminated safety glass. They are suitable for all applications that demand enhanced safety characteristics or high resistance to thermal, dynamic or static loads.

Safety glasses in different variants

Our safety glasses are available as thermally toughened safety glass, heat-soaked thermally toughened safety glass, laminated safety glass as well as heat strengthened glass. All variants are eminently suitable for both exterior and interior applications, and their entire surface can be enamelled or printed prior to the tempering process.

Thermally toughened safety glass

Function & properties:

Our thermally toughened safety glass have a higher flexural strength achieved through a thermal treatment and produce a characteristic breakage pattern. The tempering process makes these glasses considerably more resilient and allows them to be subjected to up to five times greater stress than standard float glass. In the event of breakage, the fine, crumbled, blunt fragments – typical of thermally toughened safety glass – also greatly reduce the risk of injury. This, coupled with the small size of the individual crumbled pieces, creates a certain safety characteristic. Thanks to the fracture behaviour that occurs over the entire surface, our glasses can be easily fitted with an alarm. This can be done by placing an alarm loop in one corner of the glass and connecting it to an alarm system. Any destruction of the glass also causes damage to the alarm loop and automatically triggers an alarm. This system has been tested and approved by the German VdS (Association of Non-Life Insurers).

Applications:

In the façade, linear or punctiform supports and accessible glazing, such as partition walls, door panels, all-glass installations, fall protection glazing, glass floors, roofs or even glass columns and pillars.

Glass Type:

The monolithic thermally toughened safety glass can be further processed into laminated safety glass or multi-pane glazing.

Heat-soaked thermally toughened safety glass

Function & properties:

Other than minimizing spontaneous breakage, the properties of heat-soaked thermally toughened safety glass and its breakage pattern in the event of glass breakage are no different from those of conventional thermally toughened safety glass. During the heat soak, critical inclusions in the glass are destroyed and the glass now meets the statutory safety requirements for the use of heat-soaked thermally toughened safety glass in windows and façades at an installation height greater than 4 m above the ground and as structural glazing. 

Applications:

In the façade, linear or punctiform supports and accessible glazing, such as partition walls, door panels, all-glass installations, fall protection glazing, glass floors, roofs or even glass columns and pillars. 

Glass Type:

The monolithic heat-soaked thermally toughened safety glasses can be further processed into laminated safety glass or multi-pane glazing.

Laminated safety glass

Our laminated safety glasses consist of two or more layers of glass, which are bonded together with one or more elastic intermediate layers. This is usually a polyvinyl butyral (PVB) film. Depending on the requirements, the materials of the film differ: For example, there are softer films with sound-absorbing properties and particularly tear-resistant films for attack-resistant glazing. In addition, coloured films can be used to meet architectural preferences.

The applications of our safety glasses at a glance:

• Standard applications: Sure-footed in everyday life
• Fall protection glazing: For protection from falling
• Attack-resistant glazing: Insulating glass with impact and penetration resistant properties

Standard applications

Function & properties:

Our laminated safety glazing can be used to realise partition walls, floors, stairs or roofs made of glass. One of the many ways in which our glass provides protection is by ensuring that in the event of glass breakage, no large glass elements fall onto the traffic areas below it. 

Applications:

Partition walls, floors, stairs, roofs made of glass

Glass Type:

As monolithic laminated safety glass or in combination with multi-pane insulating glasses (double glazing, triple glazing) 

Fall protection glazing

Function & properties:

People should be protected from falling by appropriate vertical or horizontal glazing. The fall protection function is only achieved through the combined action of glass, frame and the proper attachment to the building structure. According to DIN 18008-4, fall-protection glazing is divided into categories A, B and C, which differ in terms of their areas of application, the types of glass and glass structures that can be used, and additional requirements.

Applications:

Balcony parapet walls, floor-to-ceiling glazing above the ground floor. 

Glass Type:

As monolithic laminated safety glass or in combination with multi-pane insulating glasses (double glazing, triple glazing)

Attack-resistant glazing

Function & properties:

Glass with impact-resistant or penetration resistant properties makes it more difficult for burglars and violent criminals to break through the glass and windows. The effort and time required for the attack are increased. Thus, often the “object of desire” already becomes uninteresting for the perpetrator. After damage by projectiles, striking tools or even after explosions or gunfires, the laminated safety glazings, which have been tested to standards, still exhibit considerable stability. This too provides the required protection to persons and property. The test of attack-resistant properties is carried out in accordance with the European standards EN 356 (impact and penetration resistance) and EN 1063 (ballistic security). The attack-resistant properties of our attack-resistant glazing are divided into the following four categories:

• PA: with impact resistant properties
• PB: with penetration resistant properties
• BR/SG: with bullet resistant properties
• ER: with blast resistant properties

Applications:

Façades and windows, roof glazing, winter garden glazing, noise reduction glazing

Glass Type:

As monolithic laminated safety glass or in combination with multi-pane insulating glasses (double glazing, triple glazing)

Heat strengthened glass

Function & properties:

Heat-treated glass with high flexural strength and high temperature resistance. Like tempered safety glass, it is subjected to a thermal tempering process, but in such a way that the tensile and compressive stresses induced are lower. When such a glass pane breaks, some radial cracks run from the centre of the break to the edge of the pane – similar to the fracture behaviour of normal float glass. The lower pre-stressing compared to thermally toughened safety glass means that in case of a “failure”, large fragments will be produced. After further processing into laminated safety glass (made from heat strengthened glass), the products that are created add a high residual load-bearing capacity to the existing advantages of toughened glass.

Applications:

As laminated safety glass, suitable for overhead glazing, structural glazing and point fixed glazing systems.

Glass Type:

The monolithic heat strengthened safety glasses can be further processed into laminated safety glass or multi-pane glazing.
