EXR1 / EXR2 explosion-proof glasses - Hammerglass

With the increasing threat and risk of attacks and explosions in densely populated urban areas, the need for advanced security glass for windows, doors and glass partitions increases. In sensitive urban locations, such as government buildings, embassies, banks and the like, Hammerglass offers highly effective protection that will not shatter or shatter in an explosion. In addition, the entire solution is thinner and weighs significantly less than comparable solutions based on normal glass. In addition to explosion protection, the system also offers effective barrier protection against burglary.

Explosion-tested safety glass

In the event of a powerful explosion, conventional panes of glass shatter even at a great distance from the explosion, often resulting in serious splinter injuries. In objects that are in close proximity to the explosion, even shatterproof windows are crushed, although they are made of toughened or laminated glass. Hammerglass' explosion-proof solutions hold the panes firmly in place, even in the event of a powerful explosion.

Hammerglass panes have been subjected to a series of tests in accordance with EN 13124-2. A series of explosions were carried out at different distances from the Hammerglass disk. It was demonstrated that 12mm Hammerglass panes withstand the blast generated by the explosion of 3kg of TNT at a distance of 3 metres.

Unique shatterproof lightweight solution

Explosion protection panels are available in various configurations and thicknesses depending on the level of protection required. The Hammerglass explosion protection solution, consisting of a 12mm thick Hammerglass glass pane mounted in a strong steel frame, is compatible with the building facade. The steel frame keeps the entire package in place even in the event of a powerful explosion. This shatterproof solution is thinner and weighs significantly less than comparable solutions based on regular glass.

Protects people and property

More and more shops in sensitive urban locations are opting for Hammerglass in steel profiles for their shop windows. Our system offers effective barrier protection against break-ins. At the same time, it offers explosion protection without the risk of splintering and significantly higher safety for the staff working in the shop. The installation does not cause any visible damage to existing shop windows.

CERTIFICATIONS

Hammerglass has undergone a long series of tests to ensure the material's strength and performance meets all burglary, ballistic and blast protection requirements. Hammerglass AB is ISO 9001:2015, ISO 14001:2015 and ISO 45001:2018 certified as well as PPAP for the automotive industry.

Intrusion protection

Hammerglass is certified according to the European standard EN 356 with security class P8B, which corresponds to the highest protection class for security grilles and roller shutters. To qualify for this protection class, the material must withstand 70 ax blows. It is worth noting that when the test was completed, after 72 strokes, the ax still had not punched a hole in the Hammerglass sheet.

Fire

Bulletproof glass is certified according to the European standard EN 1063. The different levels of protection are indicated by the classes BR1 to BR7, where BR1 is the lowest and BR7 is the highest protection class. The most common protection classes are BR4 and BR6. Hammerglass Ballistic Protection has been tested by the Beschussamt Ulm in Germany and certified with protection classes BR4-NS and BR6-NS (No Splinter).

Explosion

A series of tests on Hammerglass panels has been carried out in accordance with EN 13124-2 at SP (Technical Research Institute of Sweden) in Borås. Hammerglass panels in different formats were mounted in different steel frames. Then seven explosions were carried out from a distance of 3 and 5 meters respectively. As a result, 12 mm Hammerglass panels were found to withstand the blast generated by detonating 3 kg of TNT from a distance of 3 meters.
