Hammerglass Add-On is a complete integrated system of effective burglar protection designed for external or internal installation over existing windows. Hammerglass Add-On can be fitted to fixed or openable windows as well as to glass- and door sections. The Add-On profile protects and reinforces existing wooden frames, and this in turn reduces maintenance costs to a minimum. The system also provides energy savings and improvements in the U-value, as well as a noise reduction of 30 dBRw. Hammerglass Add-On is recommended by insurance companies as an alternative to anti-theft grilles and roller shutters.
Many thieves have learned how to remove grilles/roller shutters by attaching a chain to a vehicle tow bar and simply pulling the grille away from the window. Apart from interfering with the view into a shop, the grille has in many cases given the shopkeeper a false sense of security. Hammerglass Add-On provides increased protection against burglars and vandals for shops, shopping centres, public premises, industrial premises, offices, petrol stations, chemists, health centres and the like. The profiles used in the Hammerglass Add-On system are made from cold-rolled steel. In an attempted break-in the material does not offer any leverage as the steel profile only gives way at the breaking pointing itself, in contrast to the more rigid aluminium profiles which can be bent up if a tool is pressed in under the profile. Hammerglass is certified as providing protection up to Security Class P8B, which corresponds to Protection Class 3 for grilles and shutters.
Hammerglass Add-On System S is primarily used for external security glazing. In certain cases however the S profile may also be fitted internally. Hammerglass Add-On System S is fitted externally as protection against burglars and vandals, or internally as burglar and personal protection. Supplied in any RAL or NCA colours.
Hammerglass Add-On System F is used for internal security glazing, and as intermediate glazing in linked sashes. Hammerglass Add-On System F is fitted internally as burglar and personal protection. Supplied in any RAL or NCA colours.
Hammerglass Add-On System U is used primarily for internal security glazing. In certain cases however the U profile may also be fitted externally. Hammerglass Add-On System U is fitted internally as burglar and personal protection, or externally as protection against burglars and vandals. Supplied in any RAL or NCS colours, and also available in copper plate.
Hammerglass Add-On is installed only by certified installers in order to guarantee the highest quality. The glazing material consists of 4, 6, 8, 10 or 12 mm Hammerglass. The glass is fully bonded along the rim, and is fitted with coach bolts to the steel profile for optimum strength. Installation will not compromise the existing architecture. All Hammerglass panes are laser-marked with a logo and production number for traceability for the purposes of internal quality assurance and security in the event of warranty issues.
