Three Key Reasons to Choose Hammerglass ADD-On

Property owners, retail chains, and public institutions face a common challenge: How to achieve security and burglary protection without compromising on aesthetics or cost-efficiency? Traditional solutions like grilles and shutters are often perceived as unattractive, difficult to access for maintenance, and in some cases, intimidating for visitors.

Hammerglass ADD-On offers a modern, discreet, and tested window security solution that neither affects the building’s appearance nor requires extensive renovations.

A New Generation of Burglary Protection

Hammerglass ADD-On is an invisible, vandal-proof protection system mounted on the inside or outside of existing windows. The design combines shatterproof, nearly unbreakable glass with break-proof steel profiles. Installation uses full-surface adhesive and through bolts for maximum stability.

ADD-On has been installed in thousands of windows – in schools, shops, and government buildings – where the need for safety is combined with demands for a stylish and maintenance-free solution.

  1. Aesthetics & Easy Installation

    Hammerglass ADD-On is designed to replace external grilles without affecting the building’s appearance. Its discreet design makes it virtually invisible, and installation does not require window replacement.

    Example: ICA retailer Marcus chose ADD-On to avoid the "prison grille" look and improve the appearance of his store.

  2. Insurance-Approved Protection

    Contrary to popular belief, insurance companies do not require traditional grilles to approve burglary protection. Hammerglass ADD-On has been tested according to the same standards as grilles and shutters and is therefore accepted in most insurance cases. This means property owners can combine design and functionality without risking loss of compensation in the event of damage.

  3. Durability & Minimal Maintenance

    ADD-On is made of Hammerglass – a nano-treated material 300 times stronger than regular glass. It does not yellow, it is scratch-resistant, and it withstands all weather conditions. The installation is future-proof and requires virtually no ongoing maintenance.

    The result is a long-term investment that eliminates many of the issues and costs associated with, for example, rolling shutters, broken grilles, or damaged windows.

     

Conclusion: Security Without Compromise

Choosing Hammerglass ADD-On provides a modern, tested alternative to traditional burglary protection. It’s a complete solution that combines high security and discreet design with minimal maintenance and cost-effective installation. An investment that offers both safety and freedom.
