HAMMERGLASS ADD-ON

"The invisible shutter" – Complete burglar/vandal protection with break-proof profiles

The invisible shutter

Because we know that grilles and roller shutters are easily circumvented by ingenious criminals, Hammerglass offers "The Invisible Shutter" – Hammerglass ADD-ON. Apart from obstructing the view to a shop, the grille has in many cases given the shopkeeper a false sense of security because it is easy to pull off with the help of a chain attached to the vehicle's tow hitch. Hammerglass ADD-ON is the burglar protection that remains permanently in place.

Recommended alternative to grilles and roller-shutters

Hammerglass ADD-ON consists of a Hammerglass panel in a steel profile, which can be mounted both internally and externally to existing fixed or openable windows and door sections. The system provides effective protection against burglars. The ADD-ON profile in cold-rolled steel protects and reinforces existing wooden frames and significantly hampers attempted break-ins. 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. The system also provides energy savings and improvements in the U-value, as well as a noise reduction of 30 dBRw. ADD-ON is certified as providing protection up to Security Class P8B, and recommended by insurance companies as an alternative to anti-theft grilles and roller-shutters.

Installation and warranty

Hammerglass ADD-ON is installed only by recommended installers in order to guarantee the highest quality. The glazing material consists of 6 mm or 8 mm Hammerglass (10 mm or 12 mm Hammerglass for larger windows). Hammerglass is glued along the rim, then screwed through the steel profile giving the best result and a secure hold. Installation will not further 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.
