SL2 Window System Dimensions
SL2 Standard Heights
While Altair Louvre Windows 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.
Please note:
- Standard sizes will save money and improve lead times.
- 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.
- Some off-standard heights are unavailable when using 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.
SL2 Widths
There are no standard Altair Louvre widths. The maximum width of a single continuous window with multiple bays is 4000mm. Maximum widths greater than 4000mm are possible through coupling two single continuous windows on site or at the window fabricator’s factory. The bay width may be affected by Building code rules. Please discuss with your Breezway fabricator and builder.
