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

This term applies to two or more panes of glass separated by insulation at the edges and air in the centre to provide greater thermal efficiency to a window.

An inert gas, usually argon, is sealed between the panes of glass in a window instead of air. Gas is a better insulator than air, increasing the thermal value of the window.

It is the mandatory minimum specification for windows and doors used in Australia, including compliance with the Glass Standard AS 1288. The following performance tests are undertaken to verify product performance:

• AS 4420.2 Deflection Test: Positive and negative wind pressures are applied to the face of the window to test maximum deflection under wind load.
• AS 4420.3 Operating Force Test: Verifies that an opening sash is capable of opening and closing without undue effort.
• AS 4420.4 Air Infiltration Test: The air leakage of a window is tested to ensure energy and acoustic efficiency.
• AS 4420.5 Water Penetration Resistance Test: Designed to ensure no water leaks through the window into the building.
• AS 4420.6 Ultimate Strength Test: Negative and positive wind pressures are applied to at least 1.5 times the design wind pressure to prevent failure in unusual wind conditions.

Our products come with a 10-year quality guarantee. If any window or door experiences issues during the warranty period, you can contact us for an exchange or servicing.

Yes, each category offers multiple options for profiles (thermal break/non-thermal break aluminium or UPVC), glazing types, top-tier international hardware, security mesh, and surface finishes. Customers can freely combine options to tailor their ideal energy-efficient windows and doors.
