SL2® Louvre Window System

Suitable for narrow frame applications

Featuring modern architectural lines, the SL2 Altair Louver window system (52mm x 25mm) has been developed to suit narrow frame applications and installation into concrete block construction when screening is not required. The SL2 Louver window system can effectively bring natural light and ventilation into the building to reduce the need for power-hungry artificial cooling systems. A build out is required to fit a screen to the outside of the SL2 louvre Window Frame. The Easyscreen and Innoscreen Windows may be preferable if a screen is to be fitted.

While Altair SL2 Louver Window can be manufactured in any size specified, the wind and water rating for the building project will affect the maximum allowable window height and bay width. Please refer to the Altair Product Performance Warranty for technical information.

For standard heights in the Breezway SL2 Frame please see the size chart to the right. Off Standard heights are available but this will add cost and result in a fixed louvre blade to act as a filler piece.

Please note:

  • Standard Heights are measured from the lowest visible metal to the uppermost visible metal of the frame and excludes fins.
  • Off Standard Heights that are more than 5mm greater than or less than a Standard Height will have a top fixed blade to achieve the specified height. Off Standard heights that are within 5mm of a Standard Height will not have a fixed top blade.
  • Some off-standard heights are unavailable when using the 102mm Altair Louvre Galleries with the Stronghold System. For the SL2 System these include: Standard Height + 19mm to Standard Height + 30mm.
  • Refer to the product performance warranty on possible height restrictions for different blade types.
  • Standard sizes will save money and improve lead times.

SL2 Widths

There are no standard Altair Louver window widths. The desired window width can be achieved through multiple louvre bays (maximum bay width is 4000mm). The bay width may be affected by Building code rules. Please discuss with your Breezway Dealer and builder.

Maximum width based on rating of 1000Pa SLS are:
