Louver Blade Options

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

Blade Dimensions

 

Blade height
Altair Louver Windows are available with two blade heights: 4” and 6”.

Blade length
The length of the louver 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 louvers be?”.

Blade thickness
The Altair Louver design has been optimised for 1/4″ thick glass and 9/16″ thick wood blades. The use of other thicknesses will compromise the performance of the product and are not warranted by Breezway.

Blades for Stronghold
Blades that are mechanically retained by the Stronghold System (i.e. A high strength acetal pin that is inserted through the Stronghold clip, bearing and blade) are available for use with 1/4″ thick, 4″ or 6″ drilled glass or aluminum blades. For more information, visit the Stronghold System page.

Blade Material

 

Altair Louver blades can be made from glass, wood or aluminum blades.

Glass

Obscure, etched, grey, bronze, tempered for extra strength and safety, with a clear low e coating for enhanced energy efficiency, or good old sparkling clear glass! As long as it’s 1/4″ thick, almost every type of glass can be incorporated into an Altair Louver Window.

For more detailed technical information please view our Glass Blades document below.

Wood

Western Red Cedar wood blades let the breeze in and create privacy at the same time while reducing the amount of heat passing through the window. All woods can be stained to blend in with your home.

Aluminum

Aluminum blades are virtually maintenance free, can’t rust and never need painting. Our aluminum blades are offered in white, clear and bronze. Custom colors can be ordered including Decowood for that eye-catching wood look.

Key consideration

Blade type

Comments

Increased glass safetyTempered Glass
Tempered glass is around 5 times stronger than un-tempered 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 tempered glass in certain situations in the building. Tempering all glass blades is an extra precaution that is available.
Wood and AluminumWood and aluminum obviously do not shatter at all.
Clear views and maximum daylightClear GlassClear glass will maximize these considerations. Tinted glass can also be very effective with only slight reductions in daylight.
Increased insulationClear low e Glass and WoodClear glass with a low emissivity coating and wood have insulating properties to reduce the heat transfer through the blade.
Protection from heat gain due to direct sunlightGlass – tinted grey or bronze
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).
Wood and AluminumWood and aluminum are solid blades and very effective in this role.
Heat gain from direct sunlight is desirableClear GlassIn 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 – satina
This glass is obscure to provide privacy while also letting in daylight while closed.
Aluminum and WoodAluminum and wood are solid blades that will provide complete privacy while closed, but need to be open to provide daylight.
Color, visual impactAluminumAluminum blades are available in white, clear or bronze. Custom colors are also available (ex Australia) including decowood.
Wood warmth or lookWoodOur Western Red Cedar blades provide the wood “look” and the insulated benefits of wood.
Aluminum – wood grain finishAluminum blades can be finished with wood look powdercoat. This provides the appearance of wood, with the low maintenance of aluminum.
