Louvre Blade Options

With Altair® Louvre Windows you can choose blades that best suit the windows function, such as maximising views, letting in/reducing sunlight, reducing glare, gaining privacy or creating your own design style.

Blade Dimensions

Blade height
Altair Louvre Windows are available with two blade heights: 102mm (4”) and 152mm (6”).

Blade length
The length of the louvre blade is typically based on the bay width required for the window application and any length restrictions to comply with Building Codes. For more information see FAQ “How wide can my louvres be?”.

Blade thickness
The Altair Louvre design has been optimised for 6mm thick glass. The use of other thicknesses will compromise the performance of the product and are not warranted by Breezway.

Blade heights of 102mm (4”) and 152mm (6”) available.

Blade Material

Key consideration

Blade type


Increased glass safetyToughened Glass
Toughened glass is around 5 times stronger than un-toughened glass. Not only is it harder to break, but if it does break, it breaks into small fragments with square edges instead of razor-sharp shards of glass. Building codes will require toughened glass in certain situations in the building. Toughening all glass blades is an extra precaution that is available.
AluminiumAluminium obviously do not shatter at all.
Clear views and maximum daylightGlass - clearClear glass will maximise these considerations. Tinted glass can also be very effective with only slight reductions in daylight.
Protection from heat gain due to direct sunlightGlass – tinted grey or green
Reduces the Solar Heat Gain when protection from direct sunlight is wanted. This will typically be a key consideration on western elevations (as windows facing the west are exposed to hot afternoon sun).
AluminiumAluminium is a solid blade and very effective in this role.
Heat gain from direct sunlight is desirableGlass - clearIn colder seasons heat gain from sunlight is a very desirable benefit. North facing windows will typically be clear glass to get this free heating benefit from nature.
PrivacyGlass – silkscreen
These glasses are obscure to provide privacy while also letting in daylight while closed.
Aluminium Aluminium is a solid blade that will provide complete privacy while closed, but need to be open to provide daylight.
Colour, visual impactAluminiumAluminium blades can be anodised or powder coated to a wide array of colours.
Aluminium – wood grain finishAluminium blades can be finished with a wood grain look powdercoat. This provides the appearance of timber, with the low maintenance of aluminium.
