MONOPACT®

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 TSG means that in case of a “failure”, large fragments will be produced. After further processing into laminated safety glass (LSG made from HSG), the products that are created add a high residual load-bearing capacity to the existing advantages of toughened glass.

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

Other than minimizing spontaneous breakage, the properties of heat-soaked TSG and its breakage pattern in the event of glass breakage are no different from those of conventional tempered 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 tempered safety glass in windows and façades at an installation height greater than 4 m above the ground and as structural glazing.

The monolithic heat-soaked tempered safety glasses can be further processed into laminated safety glass (LSG) or multi-pane glazing.

Our monolithic MONOPACT® TSGs 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 TSG—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 VdS (Association of Non-Life Insurers).
