Breezway Louvre Windows

WHY is Louvre Windows 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.
