The SlimlineTM Window System

Suitable for narrow frame applications

Breezway Altair Louvre Slimline Window System

Featuring modern architectural lines, the Slimline Altair Louvre Window System has been developed to suit narrow frame applications and installation into concrete block construction when screening is not required. The Slimline Window System can effectively bring natural light and ventilation into the building to reduce the need for power-hungry artificial cooling systems.

Slimline 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.

For standard heights in the Breezway Slimline 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.
  • Slimline windows with multiple bays and heights of over 10 and 16 blades respectively for 152mm and 102mm Galleries will require Heavy Duty Mullions.
  • Slimline Window Systems with Fixed Galleries consist of 152mm clips and blades spaced as far apart as 102mm clips are spaced on normal galleries. Fixed galleries are permanently fixed with the blades at a 45 degree angle.
  • Slimline Window Systems with Fixed Galleries do not meet water penetration requirements.
  • Slimline Window Systems with Fixed Galleries are only available in standard heights.
  • Refer to the product performance warranty on possible height restrictions for different blade types.
  • Standard sizes will save money and improve lead times.

Slimline Widths

There are no standard Altair Louvre 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.
