Premier Security Consultants is an official supplier of Hammerglass products
Hammerglass, which is made by specialists in Sweden, is 300 times stronger than glass and is half the weight. It is available in 6, 8, 10, 12, 15, 17 and 20 mm sheets, and is recognised and licenced by Secured by Design and certified according to BS EN 356, 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. In the case of Hammerglass, the Swedish National Testing and Research Institute gave up the test after 72 blows and then had to use a forklift truck twice to pull the axe out of the glass!
Glazed doors and windows are the most vulnerable part of any building design. However, in the retail market, they are crucial to displaying merchandise as well as contributing to the overall aesthetics of a shop front.
Smash and Grab burglaries are favoured by thieves due to the small amount of time it takes to carry out and the high-value reward that comes with it. Latest Metropolitan Police figures show that moped-enabled crime has risen from 1,053 in 2014 to 7,668 in 2017. So how can smash and grab robberies be prevented? Carrying out attacks with an axe, sledgehammer, brick or other devices, thieves can break through a shopfront window in as little as 20 seconds.
This problem is completely eliminated with Hammerglass.
Hammerglass is 300 times stronger than normal glass and is tested to Security Class P8B (equivalent to the highest safety rating for grilles and roller shutters). Featuring a unique coating of silicon oxide, Hammerglass is almost as resistant to scratches as normal glass, providing a high level of protection with all the aesthetic properties of normal glass.

FIVE THINGS THAT WON'T BREAK HAMMERGLASS
Produced by a specialist team in Sweden, Hammerglass is an extremely durable and resilient solution. 300 times stronger than normal glass, Hammerglass has the capability to withstand an incredible amount of force. Here are five things that won’t break Hammerglass:
- 72 Axe Blows
To adhere to security class P8B, a safety rating most typically associated with grilles and rolling shutters, Hammerglass has to be able to withstand 70 axe blows. In safety testing, the process was abandoned after 72 blows. A forklift truck was called upon twice to remove the axe from the glass, a true testament to just how strong Hammerglass is!
Stiletto heels may still be in vogue, but the pressure created by the force on the heel can cause irreparable damage to glass and other materials. In November 2014, a visitor wearing stilettos caused the glass walkway above Tower Bridge, London, to crack. The 530kg panel easily succumbed to the pressure of the heel and has also cracked under the force of a small glass bottle which had been dropped. Hammerglass, however, can survive the pressure of 1,200 women wearing stiletto heels before cracks appear.
- Pressure Washer
Pressure washers are extremely powerful pieces of equipment and can easily cause harm to someone if they walk into the path of the stream of water. Astoundingly it would take 1,739 pressure washers, aimed at the same time, to damage Hammerglass – although it is not advised to clean your windows with this many!
Despite their heavy weight, Elephants don’t exert that much pressure when they move, as they keep two feet on the floor at all times when walking. Because of this, Hammerglass can withstand the pressure of an astonishing 24,000 elephants.
- Gun Shots
Although bullet-proof glass is largely considered to be a myth, as ‘bullet-proof glass’ is actually not glass at all. The preferred term is ‘bullet-resistant’, with the material actually made out of acrylic, polycarbonate, or Glass-Clad Polycarbonate. Hammerglass is resilient enough to stay in-tact under the pressure of large volumes of gun shots. In fact, it would take 174 continual gun shots to cause even a crack in Hammerglass.
Hammerglass is a virtually unbreakable glass solution for either commercial, residential or industrial use. To find out more about Hammerglass, contact us on 0208 559 8295 to find out how we can help you.
*Calculations based on the strength of annealed glass, which can typically withstand between 40MPa and 70MPa of pressure. Hammerglass is 300 times tougher than annealed and its resistance would be 12,000-21,000MPa.
Types of Hammerglass
Hammerglass is the new generation of unbreakable glass in nano surface-treated polycarbonate, and provides suitable protection in all environments where there is a risk of glass breakage, burglary or vandalism: In shops, shopping centres, public areas, local government property, schools, sports facilities, police stations, offices and industrial premises – but also in private houses and apartments.
Preventing burglary is all about buying time. When a burglar finds that it is taking too long to break into a property, the attempted break-in is more often than not abandoned. The weakest point in most properties is frequently its windows and doors with glass panes. If these flat glass panes are replaced with unbreakable Hammerglass panes, the result will be a real increase in burglar protection. Nothing is more depressing than replacing a vandalised or broken glass pane, only to find two weeks later that the same pane has been broken once again. Repeated glass replacement in exposed environments is a very expensive undertaking.
The cost of replacing existing glass with Hammerglass, on the other hand, is low when compared with what a burglary or an act of vandalism costs the property owner in terms of money, inconvenience, wasted time and – last but not least – the unpleasant realisation that a stranger has entered his/her private home or office. In the case of new build properties or extensions to existing properties, the additional cost entailed by ordering windows with Hammerglass panes is only marginal. Hammerglass is an effective, safe and worthwhile protection against burglary and vandalism.
No more broken glass
An 8 mm Hammerglass panel is as strong and durable as 24 mm armoured glass, a bolted-on security grille or a roller shutter certified as being of Protection Class 3. It is impossible to kick in a Hammerglass pane, a baseball bat will have no effect on it, and not even a paving stone thrown with full force is capable of breaking the pane.
Hammerglass thus provides excellent protection for property against burglars and vandals, and also personal protection from projectiles and explosions, for example. Hammerglass is certified as being of Security Class P8B, which corresponds to the highest protection class for security grilles and roller shutters. In order to qualify for this protection class it is required that the material withstand 70 axe strokes. It is worth noting that, when the test was terminated after 72 axe strokes, the axe had still failed to make a hole in the Hammerglass pane.
For re-glazing with unbreakable glass in an existing building, suitable for example for older window sashes. Normally the outer or inner pane is replaced with Hammerglass, but intermediate glazing in linked sashes also occurs. At a thickness of 6 mm, supplementary glazing with Hammerglass Single contributes to a noise reduction of 30 dBRw. The system is approved as being of up to Security Class P8B (corresponds to Protection Class 3).
An insulating glass system consisting of Hammerglass in combination with any glass in a double or triple glazing structure: Sun protection glass, low energy glass, laminated glass, Cotswold etc. Hammerglass Insulate has a U-value as low as 0.65 in a triple glazing configuration. The system also contributes to excellent noise reduction. Hammerglass Insulate is certified as being of up to Security Class P8B. 5 years full insulating glass warranty.
Hammerglass Add-On for complementary glazing over an existing sash or frame is a discrete alternative to a security grille or roller shutter. It does not advertise the fact that there is something in the property to be protected – for example a computer room in a school – which is precisely the risk posed by a security grille. The profile in cold-rolled steel plate lacks leverage points and thus it cannot simply be pulled away in an attempted break-in. Hammerglass Add-On will not compromise the existing architecture.
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.
