Windows & doors

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 windows

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.

Window systems

Hammerglass AB supplies ready-made systems which are suitable for more or less all window types and fenestrations. We supply to trained retailers across the country, and to all window- and aluminium producers. Our authorised retailers are accustomed to providing an integrated approach when assessing customers’ protection needs. They are also able to offer advice on other parts of the property where security may need to be reinforced.

HAMMERGLASS SINGLE

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). MORE>>

HAMMERGLASS INSULATE

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 noise reduction of up to 37 dBRw. Hammerglass Insulate is certified as being of up to Security Class P8B. 5 years full insulating glass warranty. MORE>>

HAMMERGLASS ADD-ON

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.
