A coated or tinted glazing with optical properties that is transparent to some wavelengths of energy and reflective to others. Typical spectrally selective coatings remain transparent to visible light while effectively reflecting short-wave and long-wave infrared radiation.

This term applies to two or more panes of glass separated by insulation along the edges and air in the centre to deliver significantly greater thermal efficiency and condensation resistance for windows.

An inert gas, commonly argon, is hermetically sealed between the glass panes instead of air. Because gas is a superior thermal insulator compared to regular air, it optimizes the overall insulating and U-value performance of the window.

AS2047 is the mandatory minimum specification for windows and doors used in Australia, including compliance with the Glass Standard AS 1288. Products undergo rigorous laboratory verification tests including:

• AS 4420.2 Deflection Test: Assesses maximum structural deflection under positive and negative wind load pressures.
• AS 4420.3 Operating Force Test: Verifies opening sashes operate smoothly without excessive effort.
• AS 4420.4 Air Infiltration Test: Measures air leakage to guarantee optimal acoustic and thermal insulation.
• AS 4420.5 Water Penetration Resistance Test: Ensures high pressure resistance against water entering the building.
• AS 4420.6 Ultimate Strength Test: Applies at least 1.5 times the design wind pressure to confirm structural integrity in critical conditions.

The 6063-T5 high-quality thermal break aluminium profile integrates an insulating barrier between the interior and exterior aluminium sections. This thermal barrier prevents conductive heat transfer, keeping interior environments cool during summer and warm during winter while reducing HVAC power consumption.

A complete range of hardware brands is offered including German (Roto, Siegenia, Geze), Australian (Doric), and premium domestic systems. Surface finishes include powder coating, anodized, electrophoresis, wood grain textures, and fluorine carbon coatings to suit diverse architectural styles.
