Ballistic protection

In a changing world where gunfire, terrorist attacks, vandalism and burglary are increasingly becoming a part of everyday life, there is a growing need for advanced protective products. Hammerglass Ballistic Protection comprises unique, lightweight ballistic-resistant solutions in protection classes BR4-NS and BR6-NS, where laminated glass sheets are combined with a Hammerglass sheet to provide the lowest possible weight and thickness. Based on our experience and knowledge we are able to supply personal protection for risk objects within state and local authorities, industry and for the private citizen. Our splinter-free solutions are extremely suitable for the protection of premises where threats may arise: Foreign embassies, national and local government offices, banks, jewelry stores and other retail outlets, hotels and private residences.

Classification of bullet resistant glass

BR1 The lowest ballistic protection class where a stronger glazing panel is tested with a light weapon caliber .22 LR. To pass the test, the panel must withstand 3 shots fired from a distance of 10 metres.
BR4 Ballistic protection class according to which the glazing panel is tested with a .44 Magnum revolver. To pass the test, the panel must withstand 3 shots fired from a distance of 5 metres.
BR6 Higher ballistic protection class where a stronger glazing panel is tested with a high-speed weapon (automatic carbine) and 7.62x51 NATO ammunition (also known as 30-06). To pass the test, the panel must withstand 3 shots fired from a distance of 10 metres.
NS The glazing panel meets the NS (No Splinter) class requirements if the inner glass layer is not broken in the test. NS classification means that no glass splinters or fragments enter the protected space in the event of gunfire.

Ballistic-resistant glass is certified in accordance with European Standard EN 1063. The various levels of protection are indicated by classes BR1 to BR7, where BR1 is the lowest protection class and BR7 the highest. The most common protection classes are BR4 and BR6. Hammerglass Ballistic Protection is tested by Beschussamt Ulm in Germany and certified as compliant with protection classes BR4-NS and BR6-NS.

Same protection – lower thickness, lower weight

Bullet proof or bullet resistant glass is available in a variety of thicknesses depending on the required level of protection. Hammerglass Ballistic Protection comprises a number of glass sheets laminated together with a Hammerglass sheet. This splinter-free solution is thinner and weighs considerably less than comparable glass-only solutions, and this proves a great advantage in many situations – not least where sliding and swing doors are involved. A BR6-NS glazing solution comprising glass alone is 63 mm thick and weighs close to 160 kg/m². By using Hammerglass in the package, the thickness is reduced to 39 mm and the weight to 90 kg/m².
