Bullet Proof Glass
In an ever more violent world where gunfire, terrorist attacks, vandalism and burglary are becoming part of everyday life, the need for advanced protection products is increasing. Hammerglass ballistic protection comprises unique, lightweight bullet-resistant solutions in the higher protection classes BR4-NS and BR6-NS (No Splinter), where laminated glass sheets are combined with a Hammerglass sheet to provide the lowest possible weight and thickness. With our years of experience and extensive knowledge we are actively developing personal protection means for high-risk targets within national and local authorities and industry and commerce, as well as 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, media companies, VIP-residences, military establishments, nuclear power stations etc.
Same protection – Lower thickness – Lower weight
Bulletproof or bullet-resistant glass is available in a variety of thicknesses depending on the required level of protection. Hammerglass ballistic glass solutions comprise 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. Mounting in Hammerglass stainless steel bullet-proof reinforced partitions (Security Classes FB4 and FB6, EN 1522) provides complete protection against ballistic attacks. The ballistic resistance relates to both the glass and the accompanying frame.

CLASS | WEAPON | CALIBER | DISTANCE |
VELOCITY | SHOTS | LAMINATED GLASS | HMG PRODUCT |
BR4-NS | Handgun | .44 Magnum | 5 m | 440 m/s | 3 | 47 mm – 118 kg/m² | HmG BR4NS 23 mm – 54,0 kg/m² |
BR6-NS | Rifle | 7.62×51 mm | 10 m | 830 m/s | 3 | 63 mm – 159 kg/m² | HmG BR6NS 39 mm – 90,0 kg/m² |
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 7.62×51 NATO ammunition (also known as .308 Winchester). 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. |
