The Dualair^® Component System

Secondary Glazed Louvres

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. This makes it ideal for apartment or school projects, particularly those with high Rw or low U-value requirements.

Watch a video about the benefits of the Dualair System

Water Penetration

Significantly improved water penetration resistance up to 620Pa at floor to ceiling window sizes.

Maximum Ventilation

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 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 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
