Using high-strength chain winders and stable friction stays, the window opens smoothly and holds firmly at multiple positions, providing flexible ventilation and safe day-to-day use.
Strong Sealing & Weather Resistance
The perimeter EPDM gaskets and engineered drainage chambers ensure reliable air tightness, water tightness, and wind load resistance — suitable for coastal and inland regions.
High Thermal Performance
With thermally broken aluminium profiles and insulated Low-E glazing, the system reaches a calculated whole-window U-Value of 1.832 W/m²·K, significantly reducing heat transfer and enhancing overall comfort.
Balanced Solar Control
The glazing system provides a whole-window SHGC around 0.48–0.56, offering an ideal balance between winter solar gain and summer heat rejection for mixed climates like South Australia.
Maximum Daylight & Wide View
Slim sightlines with a visible light transmittance of 0.645 keep interior spaces bright and clear throughout the day.
Condensation Resistance
The thermal break design improves inner-surface temperatures, reducing the likelihood of condensation and ensuring year-round comfort.
Thermal & Non-Thermal Options
Available in both non-thermal aluminium and thermally broken series to meet various energy-efficiency standards and project budgets.
Compatible with Double Glazing
Suitable for all standard IGU options including Low-E, Argon-filled, laminated, and sound-control glass configurations.
