High Performance Altair® Louver Windows

Altair® Louver Windows seal tightly to give the best performance possible from a louver window.

60 years experience manufacturing louver windows
Judging the performance of a louver window can be done in two ways, firstly by its performance in the field and secondly by its performance in a laboratory testing environment.

In field performance
The Altair Louver design now has some ten years field experience in Australia, Hawaii and across the world and is widely recognised as a proven performer to International Standards.

Altair Louvers & Hurricane Yasi

On 2nd February 2011 many of our customers were hit by Australia’s largest Hurricane, Category 5 Hurricane Yasi with wind speeds up to 180mph. You can learn more about Hurricane Yasi and read how our customer’s Altair Louvers performed.

Laboratory testing
Over 150 tests have been completed on Breezway louver products in a range of sizes and many more trials during Product Development. These are conducted by National Certified Testing Laboratories (NCTL) in the American Association for Laboratory Accreditation (AALA) program and the National Association of Testing Authorities (NATA) accredited laboratories in Australia. Tests have been successfully completed Structural Test Pressure at 52.5psf (145 MPH Wind Velocity) and 5.25psf Water Resistance.

Product Design

Altair® Louvers are a high quality window system that is built to last.

The Altair® Louver gallery


The Altair Louver encompasses many innovative and patented inventions that provide improved product strength, performance and flexibility to our customers. Please note there are other louver windows on the market, so it is important to check that you are getting a genuine Altair Louver.

Louver Blade Clips


The clips are designed to ensure the louver blade is fully engaged and when closed a smooth continuous surface is created for improved aesthetics, cleaning and draining of water.

The Altair Louver clips incorporate patented concealed primary and secondary drainage channels that direct the flow of any water to the outside of the building. This is a fundamental contributor to the high water performance of the Altair Louver.



The bearings in the Altair Louver are manufactured from high quality acetal. Acetal is a high strength plastic that ensures a long product life through its high strength, low friction properties and high resistance to fatigue.

Breezway’s patented bearing is injected moulded and incorporates a “living hinge” system that when engaged with the clip and louver channel provides a system that pulls the clip in tight against the channel for improved sealing when closed and disengages in the open position for easy operation.

The bearing of the Altair Louver is also designed to fit deeply inside the Altair Louver clip to grip the louver blade and provide a positive engagement, increased strength and greater resistance to forced entry.

Rack and Pinion




The bearing and clips pivot via T shaped operating bars that engage with the bearings through a rack and pinion mechanism. This provides distribution of load and enables a strong locking force and ability to exceed 40,000 open/close cycles. That’s three times a day for over thirty five years.

The Altair louver is made from aluminum, stainless steel and industrial grade plastics. The Altair Louver handles are made of high strength acetal and stainless steel. The acetal in particular provides a high strength, flexible handle, which unlike aluminum handle it will spring back to its original shape and position, even when bent severely.
