Dualair® System Now Compatible with Flat 150mm Commercial Framing

27 March 2026

The Breezway Altair Dualair System has been developed to deliver a high performance, sophisticated secondary glazed louvre window for the commercial market and is now available with most flat 150mm commercial framing. The system provides excellent ventilation to keep buildings naturally comfortable while offering high water penetration resistance, sound acoustics and increased thermal performance.

Superior aesthetics are achieved through the primary and secondary window being identical window types and both contained within a single frame, saving on installation costs too. The outside louvre gallery can utilise glass blades for uninterrupted views. Alternatively aluminium blades or patterned glass can be used for adjustable external shading, privacy or decorative effects on the building facade.

High Water Penetration Resistance – The Dualair System can achieve up to 620 pascal ratings at floor to ceiling heights. This is a 20% performance improvement at window sizes twice as wide and three times as high.

Sound Insulation – Through the use of two louvre galleries inside one frame, significantly high Rw ratings of 35 can be achieved to reduce outdoor noise.

Thermal Insulation – U-values ranging from 2.4 to 3.4 give comparable performance to double glazed windows with thermally broken frames.
