The DualairTM Component System

The DualairTM Component System

Breezway’s new Altair Dualair Component System has been carefully designed to deliver a high performance dual glazed louvre system to the commercial market.

Dualair at a Glance

The secondary glazed unit for commercial applications

The Altair Dualair Louvre Component System is a secondary glazed unit with sophisticated aesthetics and reduced installation costs making it ideal for apartment or school projects, particularly those with high Rw or low U-value requirements.

Water Penetration

Significantly improved water penetration resistance. Up to 620Pa Water Penetration Resistance at floor to ceiling window sizes.

Maximum Ventilation

Maximum ventilation to keep building occupants comfortable all year round.

Aesthetics

Single window unit gives better aesthetics. Using aluminium or patterned blades can create a decorative effect to the building facade.

Reduced Installation Costs

Secondary glazing within a single frame results in a single installation occasion.

Acoustic Insulation

Excellent sound acoustics to reduce outdoor noise – Rw ratings up to 35.

Thermal Insulation

U-values ranging from 2.4 to 3.3 give comparable performance to double glazed windows with thermally broken frames.

Shading / Privacy

Use aluminium or patterned glass blades on outer blades to provide shading and privacy.

Dualair Component System 3D Models

Online viewing of 3D models is a relatively new technology. Please note the models shown below are rendered animations only. For more technical detail please view the CAD and BIM model section below. Viewing 3D models requires a fast internet connection and reasonably high speed computer processor. Viewing may not be possible on some older computers. We recommend Google Chrome for the best viewing results.

NOTE: Whenever you see this symbol logo-mark-25x25 click on an illustration to view a 3D interactive version. Rotate the model by using your left mouse button or pan the model by using your right mouse button. Use your mouse wheel to zoom. Please note this is a rendered model only.

Dualair System Standard Heights

While the Altair Dualair Component System is available in all of the standard heights noted, 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 Altair Dualair Louvre Gallery standard heights please see the size chart on the right. Off Standard heights and 102mm heights are not available.

Dualair System Widths

There are no standard Altair Louvre widths. The Dualair System is only supplied as a component system for single bays however the bay width may be affected by Building code rules. Please discuss with your Breezway Dealer and builder.

Altair Powerlouvre Windows

  • Minimum bay width for 2-9 blade high windows = 400mm
  • Minimum bay width for 10-18 blade high windows = 500mm

A tight specification will help to make sure that what you specify ends up in your building thereby achieving your design objectives.

The louvre windows shall be Breezway Altair Dualair Secondary Glazed Louvre Windows.

Unique features:

  • Altair Louvres in a secondary glazing configuration within 150mm commercial glazing.
  • Minimum acoustic rating of R’w.35.
  • Maximum U-value of 3.8 W/m2.K.
  • Optional pressure equalising design and patented drainage channels for superior water performance.
  • Patented ‘Living Hinge’ design that pulls the clips tightly against the channel when closed for superior water performance and air infiltration.
  • Low profile keylock with lock barrel housed inside the louvre channel.
  • Passed testing to 40,000 open/close cycles for long operational life.
