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.

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.

Hammerglass Windows

300 times stronger & half the weight of ordinary glass

Hammerglass Windows, No more broken windows!

Do you have problems with broken glass, burglary or vandalism? Hammerglass is a durable abrasion-resistant polycarbonate sheet, 300 times stronger than glass – and virtually unbreakable. With their unique coating, Hammerglass sheets are resistant to most chemicals and acids. The coating also provides a UV protection of 99.96% so that the glass will not become cloudy, bleached or otherwise age over time.

What is Hammerglass?

Virtually Unbreakable Hammerglass is a durable abrasion-resistant polycarbonate sheet, 300 times stronger than glass – and virtually unbreakable. With its unique surface coating of silicon oxide (can be compared to a layer of glass) Hammerglass sheets are resistant to most chemicals and acids. The coating also provides a UV protection of 99.96% so that the glass will not become cloudy, bleached or otherwise age over time.

Various Thicknesses & Dimensions Hammerglass is available in 4, 6, 8, 10, 12, 15, 17 and 20 mm sheets. Typically, the sheets measure 2000×3000 mm, but we can make larger or smaller sheets to minimize wastage in larger series of the same size.

Certified Security Rating Hammerglass is certified according to Security Class P8B, which is equivalent to the highest safety rating for anti-burglary grilles and rolling shutters. To obtain this classification the glass must withstand 70 blows with an axe. After 72 axe blows, the Swedish National Testing and Research Institute gave up the test. They had to use a forklift truck twice to pull the axe out of the glass!

Instead of security grilles and roller shutters

Hammerglass is the new generation of unbreakable glass in nanotechnology treated polycarbonate. In addition, Hammerglass provides a whole system of unbreakable glass solutions for new construction, conversions and Add-Ons. Hammerglass is an appropriate protection in any environment where there is the risk of burglary or vandalism: shops, shopping malls, public buildings, municipalities, schools, sports centres, police stations, offices and industries – but also in private homes and apartments.Preventing burglaries is about buying time. If a thief thinks that it will take too long to break in, he usually won’t continue. The weakest point of most buildings is usually windows and doors with glass panes. Replacing glass panes with unbreakable Hammerglass sheets significantly increases security.

Hammerglass is certified according to Security Class P8B, which is equivalent to the highest safety rating for anti-burglary grilles and roller shutters. We deliver to trained dealers across the country, and to all window and aluminium producers.

Protection against vandalism

Nothing is more frustrating than replacing a pane of glass, only to have to replace it again two weeks later because the same window got smashed again. Frequent changes of glass in exposed environments cost large sums. The additional cost of switching to Hammerglass is quickly recovered. Hammerglass sheets can withstand incredible amounts of force. It is impossible to break a Hammerglass window with a kick, a baseball bat makes no dent – not even a paving stone thrown at full force can smash a Hammerglass window.Thanks to its specially developed coating, Hammerglass is highly abrasion-resistant and withstands most chemicals. Graffiti can be removed with solvent. The surface layer also provides 99.96% UV protection, which means that the glass will not become cloudy or discoloured over time.

Can Hammerglass burn?

6 MYTHS about Hammerglass – which it is time to shatter.

We fully understand that old knowledge can persist. But when it is no longer true and also thwarts a good and safe result, we gladly wave the teacher’s stick and sort out the misunderstandings. Hammerglass differs in many important aspects from “ordinary” PC and other materials. These are the most persistent myths we encounter:

 

1. Hammerglass turns yellow with time.

NO. Hammerglass does not turn yellow. The early polycarbonates did that and there are still polycarbonate variants that turn yellow after a while. Hammerglass should not be compared to “regular” polycarbonate. Hammerglass is hard-coated, almost unbreakable and has a nanotechnological surface of smooth silicon oxide that provides UV protection of 99.96%. 

2. Hammerglass becomes cloudy when cleaned.

NO. Thanks to its smooth surface, graffiti can be wiped off with regular detergent and the Hammerglass surface remains transparent and optically clear.

3. Hammerglass burns.

NO. Hammerglass self-extinguishes when ignited.

4. Hammerglass can be compared to plexiglass.

NO. The term plexiglass refers to most “plastic sheets in general”, which in itself is wrong because Plexiglas® is a proprietary brand for the polymethylmethacrylate (PMMA) acrylic plastic. Hammerglass is 300 times stronger than glass whereas plexiglass is only about 30 times stronger than ordinary glass. Plexiglass is sensitive to scratches, gets a milky surface on contact with solvents and burns on ignition.

5. Hammerglass can be compared to acrylic plastic.

NO. For the same reasons as myth number 4. Acrylic burns, it is sensitive to solvents and cracks on impact. Hammerglass does not. Acrylic is easier to hot-mould than polycarbonate, but Hammerglass can be hot-moulded and bent to the desired shape with special tools, still retaining all the advantages that distinguish the material from acrylic.

6. Hammerglass gets scratched as easily as any other plastic.

NO. The hard-coated, smooth surface of Hammerglass is scratch-resistant. It will get scratched over time if particularly exposed, but not to the same extent as acrylic or plexiglass.
