Stronghold® System
Strong & Secure
Altair Louvres with the Stronghold System are a logical inclusion when extra strength and safety is required in commercial or residential buildings.
Leaf Architecture finalised the design concept for this project with the objective of enclosing the school balconies and allowing the school to utilize the walkways between the classrooms. They integrated Breezway Altair louvres and the Stronghold System into the design. View project.
Safety without Compromise
The Stronghold® System is an Altair Louvre Window option that mechanically locks louvre blades into their clips to improve blade retention and safety. It is designed for applications requiring fall-prevention measures or additional strength, while retaining natural ventilation and outward views. Final compliance depends on the complete window configuration, opening restriction, installation and applicable building requirements.

Added Safety
Altair Louvres with the Stronghold System mechanically locks louvre blades into their clips to increase the amount of force the window can resist. With blades only able to be removed using a special tool, the window is more secure and your building is safer.
Extra Space
The Stronghold System can be used in multi-story applications. A balcony enclosure or wintergarden can be created to provide extra year-round living space or as a barrier against outdoor noise. Occupants can enjoy the winter sun in a protected spot or take advantage of fresh breezes.
Ventilation
The Stronghold System allows our windows to easily meet the fall prevention requirements of the Australian Building Code with only a slight reduction in ventilation, and without obstructing outdoor views. Ideal for use more than 2 metres above ground level or for windows that require extra strength for example in wet rooms.
Frequently Asked Questions
Why would I choose the Stronghold® System?
The Stronghold® System is ideal for projects where additional strength and safety are required, including multi-storey residential buildings, apartments, schools, healthcare facilities and commercial developments. By securely retaining the louvre blades within the window system, it helps create safer environments without sacrificing airflow or outdoor views.
How does the Stronghold® System improve building safety without compromising design?
The Stronghold® System has been developed to increase the strength and security of Altair Louvre Windows by mechanically locking the blades into place. This helps improve resistance to applied loads while preserving the clean appearance, natural ventilation, and unobstructed views that architects and designers value. Suitable for residential, education, healthcare and commercial projects, the system provides an effective balance between safety, performance and aesthetics.
Can the Stronghold® System help meet Australian fall prevention requirements?
Yes. Altair Louvre Windows with the Stronghold® System have been designed to assist with meeting Australian Building Code fall prevention requirements when used with suitable restricted openings. The system has been extensively tested and is commonly specified for applications where windows are located more than two metres above ground level.
Does the Stronghold® System reduce ventilation?
The Stronghold® System allows Breezway Louvre Windows to meet fall prevention requirements with only a slight reduction in ventilation. Occupants can still enjoy natural airflow, cooling breezes and unobstructed views, making it a practical solution for buildings where both safety and comfort are important.
