In Australia’s construction industry, window and door systems must meet strict national standards to ensure safety, durability, and performance.
Among these, AS2047, AS4284, and AS1288 are the three most recognized standards — and though they’re related, each focuses on a different aspect of design and testing.
AS2047: Overall Window and Door Performance
AS2047 (Windows and External Glazed Doors in Buildings) is the mandatory certification for all external windows and glazed doors used in Australian buildings.
It assesses the entire system performance, rather than individual components.
The test evaluates wind pressure resistance, water penetration, air infiltration, and operating force.
In other words, a product that passes AS2047 can withstand heavy rain, high winds, and frequent use — while maintaining its structural integrity and smooth operation.
AS2047 is the essential benchmark that determines whether a window or door is suitable for installation in Australia.
Without AS2047 compliance, no window system can legally be installed in residential or commercial projects.
AS4284: Facade and Curtain Wall System Testing
AS4284 (Testing of Building Facades) applies primarily to curtain wall and facade systems used in high-rise and commercial buildings.
It simulates real environmental conditions — including dynamic wind, rain, and pressure differentials — to evaluate how an entire wall system performs under extreme weather.
While AS2047 focuses on a single window unit, AS4284 evaluates a complete wall assembly.
This makes it crucial for large-scale developments and architectural facades, where air and water sealing, drainage, and structural performance must work as a unified system.
Simply put, AS2047 ensures a window works properly, while AS4284 ensures a building’s entire facade stays watertight and secure.
AS1288: Glass Safety and Installation Standard
AS1288 (Glass in Buildings – Selection and Installation) governs how glass should be selected, sized, and installed in buildings.
It ensures that the type and thickness of glass used are safe for their intended location, based on wind load, height, and exposure.
This standard specifies minimum thickness, edge support, and glass type — whether toughened, laminated, or safety glass.
It’s especially critical for areas such as bathrooms, balustrades, and high-traffic zones where glass breakage could endanger people.
AS1288 isn’t about window performance — it’s about glass safety.
Together with AS2047 and AS4284, it ensures every window system in Australia is both structurally sound and safe to use.
How They Work Together
In real projects, these three standards complement each other.
AS2047 verifies the window’s performance as a system,
AS1288 ensures the safety of the glass used,
and AS4284 applies to advanced facade systems in high-rise or commercial settings.
At M&C Windows & Doors, all our export products are designed and tested according to AS2047 standards.
Our glazing and installation procedures strictly follow AS1288,
and for large-scale facade projects, we support AS4284 testing and certification as well.
Together, these standards ensure our windows deliver the reliability and performance Australian clients expect.
AS2047, AS4284, and AS1288 each address a critical aspect of window and facade construction — performance, structure, and safety.
Understanding them helps builders, architects, and homeowners make informed decisions when choosing door and window systems.
