The pane of PYRANOVA® secure glass was first subjected to a fire test for 30 minutes and then attacked with a 9 mm Luger army pistol. The extremely hot glass laminate from SCHOTT resisted three shots fired from a 9 mm caliber gun at a speed of 400 m/s.

Glass laminates from SCHOTT are the world’s first specialty glasses that have been successfully tested against simultaneous multiple attacks from fire and gunshot.

Various security glasses used previously provided protection against different types of attacks, but they were only able to protect against one particular type of attack at a time for a given emergency. PYRANOVA® secure and NOVOLAY® secure laminates from SCHOTT are unique in that they successfully stand up to different forms of successive attacks; i. e. a glass laminate damaged by gunshots still offers reliable protection from a fire. In the same manner, a glass pane will still stand up to gunshots after being exposed to a fire.

”This is a world first,” explains Helmut Kugelmann, Sales Manager for SCHOTT Technical Glass Solutions in Jena. ”To meet these unique demands, we have developed new, special, multifunctional laminated constructions that are made up of both highly tempered and extremely effective fire protection glass types. This type of complex structure is necessary in order to ensure that our new products are able to resist multiple simultaneous attacks,” he adds.

Testers from two independent institutes, the Beschussamt Ulm (Ballistic Test Facility in Ulm) and the Institute for Building Materials, Solid Construction and Fire Protection at the Technical University of Braunschweig, approved the tests. In this case, these extremely strong safety glasses were subjected to consecutive fire and ballistic tests.

The test certificate confirms that the glasses met the two test standards DIN EN 1363 (Fire Protection) and DIN EN 1063 (Bullet Resistance). Due to the fact that the European legislature only requires that protective glasses meet EN safety standards individually, SCHOTT became the world’s first company to voluntarily subject its safety laminates to a combination of tests.

”With our safety glass, we now offer the chance to effectively protect buildings from multiple assaults, for example bullet strikes followed by a Molotov cocktail attack. We are therefore quite confident that our glass products will be of great interest when it comes to developing security strategies for government buildings, embassies and consulates,” Helmut Kugelmann explains. The development of the new safety glass range has received support from the Thuringian State Government and the European Regional Development Fund (EFRE) as part of the research project ”Second ­Generation Multifunctional Safety Glazing” (2011 FE 0156) since October 2011.
