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.
A single louver window bay contained within a single frame.

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.
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:
Maximum Glass Blade width subject to windload & fall prevention:
Maximum Stronghold Glass Blade width subject to windload & fall prevention:
For allowable length of blades refer to AS1288 and Breezway Louver Window Product Performance Warranty.
