Altair® Louvre Window Sizes

Altair Louvre Windows are custom manufactured to order, meaning there is a wide flexibility in sizes available. There are no standard blade widths, most louvres bays are between 600mm and 900mm but can extend up to 1200mm if using the Stronghold System.

Heights

 

Standard heights do exist and are based around the chosen blade height of 102mm and 152mm. Multiples of these blades give standard window heights. Off Standard heights are available but this will add cost and result in a fixed louvre blade to act as a filler piece.

The type of window frame chosen will also affect the standard heights. Proprietary frame height will be based on the sizes for Altair Louvres plus an allowance for the outer frame type chosen. This is best discussed with your window fabricator and builder.

There are no changes to standard heights when using Altair Louvre Windows with the Stronghold. For more information, please visit the Stronghold System page.

Widths

 

There are no standard louvre blade widths.

The desired window width can be achieved through multiple louvre bays. When determining the bay widths possible a rule of thumb is the higher the wind and water performance required, the shorter the blade should be.

In cyclonic regions the bay widths may be a maximum of 600mm or in other geographic areas with lower wind loads they may extend to 900mm or more. The window frame can then be designed with multiple bays to achieve the desired frame width. With Breezway’s framing systems this can be up to 4 metres wide.

For Powerlouvre Windows, the minimum bay widths are:
2-9 blade high Powerlouvres – minimum bay width = 400mm
10-18 blade high Powerlouvres – minimum bay width = 500mm

Please note: Some off-standard heights are not available with 152mm Powerlouvres and no off-standard heights are available with 102mm Powerlouvres.

Please speak to your local window manufacturer for advice on your specific circumstances.

Maximum Blade Widths: Typically a louvre bay width (i.e the length of the blade) can be 600mm to 900mm, however Breezway can offer bay widths up to 1200mm if using the Stronghold System (please refer to the Product Performance Warranty for more information).

When replacing windows or installing new windows, a rule of thumb is the higher the wind and water performance required, the shorter the louvre blade should be. In cyclonic regions the bay widths may be a maximum of 600mm or in other geographic areas with lower wind loads they may extend up to 900mm.
