Stealth Armed Glass
Stealth Armed Glass is where advanced glass technology meets intelligent security—without compromising on style. Each toughened glass panel features an invisible metal coating that enables it to be connected to an alarm system, forming part of a 24/7 monitored security solution.

This innovation turns your glazing into an active defence layer, silently alerting you to intrusion attempts without altering the clean, frameless aesthetic of your property.
Also available in a double-glazed option, Stealth Armed Glass pairs a toughened, alarm-ready outer panel with an interior laminated safety glass for enhanced strength, insulation, and sound control.
Please note: Stealth Armed Glass is currently in pre-release and not yet available on the market. Be among the first to experience the future of integrated security.
This is smart security for modern living—elegantly embedded in every pane.

What is Stealth Windows?
Stealth Windows are a next-generation flush aluminium-frame glazing system designed to be used with casement aluminium window frames that blend advanced aesthetics with modern performance. Each glass panel features digitally printed borders that are fused into the glass during the toughening process—creating a sleek, borderless appearance where the frame and silicone are completely concealed from the outside.
This innovative design gives the illusion of frameless glass, resulting in a smooth, uninterrupted surface that reflects surrounding architecture and nature—enhancing both the exterior and interior look of any building.
More than just a visual upgrade, Stealth Windows offer improved security, structural strength, and compatibility with advanced features like double glazing and Armed Glass technology. It’s the future of window design—where form, function, and lifestyle meet in perfect balance.

Frequently Asked Questions
/ Design, lifestyle and modern living
Stealth Windows combine minimalist aesthetics with innovative glazing technology. By eliminating visible external glazing beads, the glass becomes the focal point, creating clean lines and a refined architectural finish. The glass is bonded to specially designed aluminium profiles from the inside, helping to improve resistance to external tampering. The result is a contemporary window system that brings design and security together.
Windows have a significant influence on the appearance of a building. Stealth removes the conventional external glazing beads that interrupt the glass surface, creating a cleaner, more streamlined finish. Whether used in a new home or a renovation, Stealth helps achieve a more contemporary architectural look without changing the essential function of the window.
Modern architecture increasingly emphasises clean lines, natural light and simplicity. Conventional glazing beads can create visible divisions around the glass, while Stealth offers a more seamless appearance. This makes it an attractive option for architects and homeowners looking for understated detailing that complements contemporary interiors and exterior finishes.
Stealth is designed to complement modern living by combining a refined appearance with practical functionality. Its clean glazing lines work beautifully with open-plan interiors, outdoor entertainment areas and contemporary architectural designs. With suitable glass specifications, Stealth can also support improved thermal comfort and help make indoor spaces more enjoyable throughout the year.
The digitally printed ceramic paint border conceals the structural silicone bonding, creating Stealth's signature clean finish. The border is applied before toughening, during which the ceramic paint fuses into the glass.
Standard options include black, white, matt stone grey and charcoal. Additional colours can be produced on request, providing greater flexibility to coordinate with aluminium frames, interior finishes and the overall architectural design.
Yes. Stealth offers an exciting opportunity to modernise suitable existing aluminium windows without necessarily replacing the entire frame. Because Stealth is built around standard aluminium casement frame profiles widely used in South Africa, the existing frame may be retained while the glazing system is upgraded, subject to a technical assessment.
This can provide a cleaner, more contemporary appearance and enhanced resistance to external glass removal without the cost and disruption of replacing every frame.
/ Smart upgrades and value-added opportunities
In many cases, yes. Stealth is designed around standard aluminium casement frame profiles used by manufacturers throughout South Africa. Where the existing frame is suitable and in good condition, it may be possible to retain the frame and replace the existing glazing with a Stealth Glass unit.
This creates an opportunity to upgrade the appearance and glazing security of existing windows while reducing the need for extensive frame replacement. Each installation must be assessed to confirm compatibility and suitability.
Renovations do not always require the removal of every existing window frame. Where standard aluminium casement frames remain suitable, Stealth can offer a practical way to modernise their appearance through an upgraded glazing system.
This can help property owners achieve a more contemporary finish while potentially reducing material waste, building work and disruption compared with a complete window replacement.
Attractive windows can contribute to a property's overall presentation and perceived quality. Stealth combines contemporary styling with innovative glazing and optional integrated alarm technology, giving property owners a distinctive feature to include in their renovation or new-build plans.
While the effect on resale value will depend on the property and market, Stealth offers a way to invest in both appearance and functionality.
Stealth can be specified with suitable Low-E glass and compatible double-glazing configurations to help reduce unwanted heat transfer and improve indoor comfort. The actual performance depends on the glass specification, frame configuration, building orientation and installation quality.
For projects where thermal efficiency is a priority, the appropriate glass options should be confirmed during the design and quotation process.
Yes. Stealth removes conventional external glazing beads and uses structural silicone bonding within specially designed profiles, making the glass more difficult to remove from outside. For additional protection, Stealth Armed Glass can connect compatible glass to an alarm system.
This approach allows property owners to pursue a clean architectural appearance without relying solely on visible security bars or external security additions. Security performance depends on the complete installation and specified system.
Yes. Stealth's specialised glazing system can be incorporated into suitable aluminium window and door configurations. This allows architects and homeowners to create a more consistent aesthetic across different glazed openings, including selected door applications.
The appropriate profiles, dimensions and glass specifications must be confirmed for each configuration.
