WHY is Lourves Glass Window is great for you?

It’s not uncommon to see short, wide windows (particularly Altair Louvre Windows) installed near the ceiling and above head height. These windows are commonly known as highlight or clerestory windows and besides looking great, they also offer a number of specific benefits.

Create a thermal chimney to naturally cool your building.
Hot air rises. Inside a building this means that the air near the ceiling is generally warmer than the air near the floor. Positioning windows near the ceiling provides a way for warm air to flow out of the building which encourages cool, outside air to be drawn in through the lower windows. This ‘thermal chimney’ effect avoids warm air being re-circulated inside the building resulting in a more comfortable living space. Thermal chimneys are especially beneficial on still days when there is no breeze to generate cross-flow ventilation.

Very short, very wide windows are popular for this application and Altair Louvres are an obvious choice not only because they maximise ventilation, but also because they remain functional, unlike other window types which require more square shapes to function properly.

Benefit 2: Ventilation, light and privacy.
Positioning windows above head height results in vertically angled sightlines. This means that the only thing that neighbours and passers-by can see through the window is your ceiling! This privacy removes the need for blinds or curtains on windows positioned up high and allows ventilation to be maximised while maintaining privacy.

Another often unexpected benefit of windows positioned up high is that they give pleasant diffused light. Being positioned up high generally results in the window being close up to the eaves of the building. As a result the eaves fully shade the windows for most of the day, resulting in a pleasant glow of diffused light rather than dazzling shafts of direct sunlight.

Benefit 3: Light, ventilation and security.
There are plenty of options for making Altair Louvre Windows more secure (see our blog post on “Impenetrable Security” for more info), but the simple fact is that a window that is out of reach is a more difficult and therefore unpopular target. This allows windows installed up high to be confidently left open, knowing that even if a potential intruder manages to climb up to and through the window, they would still face a significant drop down to the inside floor below the window so are most likely to ignore highlight and clerestory windows.

The Palmair 152mm fixed clip louvre system provides blades fixed at angle of 48 degrees every 89mm, for permanent ventilation. The fixed louvre is used where permanent ventilation, light, privacy, or a degree of weather proofing is required. Although the fixed clip louvre does not meet water penetration requirements, the angle and positioning of the blade holder ensure sufficient cover from adverse weather conditions.

The injection mold blade holder is designed to accept 5 to 6.38mm glass, aluminium or timber blades. The recommended maximum span of the blades is 90mm, thoughened glass is also an option for higher wind road areas.

Selecting The Right Aluminium Finish

Surface finishes are either Polyester powder coated (50 mm minimum thickness) or anodised (minimum 15 mm thickness)

Unless otherwise specified all Breezway products are finished with standard powder coat formulations from leading powder suppliers. However, overtime there will be weathering off the finish, resulting in a gradual change in appeareance. This will be evident loss in gloss, chalking, color change and erosion of powder coating. Selecting the right powder for the atmospheric conditions of the site together with correct maintenance will be critical to the ongoing appearance of the finish.

The application of high durability powder will reduce this deterioration and is essential for severe industrial, coastal or tropical environment.

Note that industry accepted color variation can occur during the aluminium anodising process.
