IGLU® System
Double glazed louvre
The revolutionary Altair® IGLU® Double Glazed Louvre System allows maximum ventilation through the window opening while providing high thermal performance.
The IGLU double glazed louvre is ideal for use in colder climates, or any applications that require higher levels of thermal insulation.

Features
Maximum Ventilation
Award Winning
Acoustic Performance
Superior sound isolation of Rw30 ideal for noisy areas.
Thermal Insulation
Customisable
Various customising options including frames, blades, colours and automation.
Frameless Glazing
No thermally compromised framing and with blade-to-blade sealing.
- 90% ventilation as per the NCC Definition of a ventilation opening. Using a more conservative and realistic definition of the ventilation opening, the thicker IGLU blades will reduce the ventilation opening to approximately 80% of the total window area.
- Winner of the 2023 Good Design Award and 2023 AGWA Design Award for ‘Most Innovative Window System’.
Ventilation
Natural ventilation is important in any home or working environment. It helps keep the air we breathe clean and fresh, preventing mould or moisture build-up whilst maintaining a connection with our outdoor environment. The IGLU Double Glazed Louvre System opens twice as wide as other window types to offer maximum ventilation and capture breezes no matter the wind direction.
Compliant & Safe
The IGLU Double Glazed Louvre incorporates the Stronghold® System to ensure compliance with Fall Prevention requirements. It has also passed BAL-40 testing for use in bushfire prone areas. With increased acoustic performance and the low-risk pinch or edge impact hazards due to soft seal-on-seal closure make the IGLU System ideal for education environments.
Energy Performance
The 22mm IGLU Blade, comprising of 5mm Low E glazing, 12mm Argon Gas filled spacer, and another layer of 5mm Low E offers the highest thermal performance of any residential louvre. This double glazed louvre is WERS rated and is ideal for use in colder climates, or any applications that require higher levels of thermal insulation.
Enhance energy efficiency and comfort with the IGLU® Double Glazed Louvre System
The Altair IGLU Double Glazed System maximizes ventilation with wide openings and provides superior wind and water performance, while also offering improved energy efficiency and excellent thermal ratings, making it ideal for energy-efficient projects.
The IGLU Clip utilises the Breezway Stronghold® System, granting superior blade retention, with all the other benefits the Stronghold System offers. The stepped nature of the IGLU Blade allows for the internal glazing layer to be retained within the clip, while the outer glazing layer finishes flush with the clip. This allows for a completely flat aesthetic to the outside of the window.
Breezway Altair IGLU Blades do not have thermally comprimising aluminium framing. Instead, the blades are capped top and bottom by rubber blade-to-blade seals, embedded into the IGU sealant, with a clean ceramic print running the perimeter of each blade to conceal the IGU spacer, while still drawing the eye through to the view outside.
