Adjustable Louvres allow you the greatest flow of air of any window when fully open. The air flow is able to be varied by changing the pitch of the louvres and by closing some blades and leaving others open. Louvres allow almost unrestricted view while maintaining ventilation. Consider this product for breezeways or to allow natural cooling by air flow through a home. Our Louvre windows can be supplied with a large variety of adjustable blades and combined with adjoining fixed sidelights within the main frame. 152mm or 102mm wide blades are available in Glass, Western Red Cedar or Aluminium adjustable blades – all can be fitted into the LouvreMaster™ window. One of the main features with our Louvre windows is the ability to fit flyscreens into the main frame without adaptors, trims, screws or unsightly turnbuckles. This saves money and is aesthetically pleasing. The 417 Series sun control shutter is designed for external sun and or privacy control in fixed panels or moving panels in the form of a hinged, sliding or a Bi-folding door.

Stronghold® System

The Stronghold System by Breezway is available as an added feature for your Series 525 Louvres to add strength and safety to your building.

Altair Louvre blades are retained by a pin that passes through the clips, bearing and blade. Once installed, the pins cannot be removed without tools and the blades are prevented from being removed from the clips. Pins are visible on the inside/underside of the clips.

The Stronghold System is ideal for multi-storey residential applicationsand enables bay widths of up to 1200mm. Please refer to the Breezway Product Performance Warranty for more information.

Mechanically Retains Blades
Complies with Fall Prevention requirements where blades are mechanically retained without obstructing outdoor views and minimises the risk of blades being dislodged by impact.

Residential Buildings
Ideal for windows more than 2m above ground or those requiring extra strength with the benefits of natural ventilation and added safety for your family.

Naturally Ventilated Buildings
Energy efficient Altair Louvres with the Stronghold System allow abundant fresh air and natural light to flow into the building to help save on running costs.

Safeguarding Against Falls
Louvre windows with the Stronghold System and with restricted openings comply with the new provisions in the Building Code of Australia for Fall Prevention through openable windows and have passed testing to the Australian Window Association’s industry code of practice “ICP.005 – Protection of Openable Window Testing Specification.” As the glazed area can be opened to allow airflow they can be used to maximise natural ventilation in multi-level applications compared to other window types.

If blades need to be removed from an Altair Stronghold Louvre Window or if broken blades need to be replaced, the removal process requires tools and will destroy certain components requiring replacement prior to new blades being re-installed.
