High Performance Altair™ Louvre Windows

Modern materials and design, strict adherance to Australian and International standards, and exhaustive testing in a NATA (National Association of Testing Authorities) certified laboratory ensure that Altair™ Louvre Windows seal tightly to give the best performance possible from a louvre window.

Wind Rating

Site wind ratings determine the maximum allowable blade lengths. For more information on allowable blade lengths, please see the Altair™ Product Performance Warranty.

Maximum Ventilation

Altair Louvre blades open close to horizontal, thereby allowing maximum ventilation through the window to cool you down the way nature intended. In effect, you get twice as much ventilation as you would through a same sized sliding window or double hung window. For more information, visit the Energy Efficiency page.

Water Rating

The firm pressure between blades and the patented design of the 'living hinge' ensure that Altair™ Louvre Windows seal tightly when closed. On rainy days water is cleverly managed to the outside of the building through the dual drainage channels concealed within the clips and by the weatherstrip and drainage holes at the bottom of the window. Please refer to the Altair™ Product Performance Warranty for various water ratings.

Air Infiltration

Windows and doors that seal tightly minimise the amount of air that can leak out of them, helping heating and cooling systems to run more efficiently. Tight sealing windows avoid cold draughts in winter and even play a role in sound insulation.

Air infiltration ratings from www.wers.net – l/m²/sec at a pressure differential of 75Pa

	Breezway Altair™ Louvre Window (1.5 l/m²/sec)
	Building Code of Australia Standard for Residential Windows (5 l/m²/sec)
	Building Code of Australia Standard for Louvre Windows (20 l/m²/sec)
	NOTE: The lower the rating the more efficient the system.

Sound

The combination of tight sealing and the thick blades used in Altair™ Louvre Windows result in a STC rating of 24 – 27 depending on the blade type.

Corrosion Resistance

Altair™ Louvre Windows are made entirely from corrosion resistant aluminium, stainless steel and industrial strength plastics for long life durability.
