Energy Benefits of Louvre Windows Over Other Window Types

  • Ventilation through the whole window area as they open twice as wide as other window types.
  • Ventilation no matter which direction the wind is blowing in comparison to awning or casement windows.
  • Maximum ventilation through large or unusually shaped window spaces that other window types cannot accommodate.
  • Ventilation through internal windows to further cool and refresh the building.

Energy savings for a mixed mode (hybrid) system are on average 59%

Carnegie Mellon


Controlled studies in 1999 and 2000 showed that as ventilation rates increase, children perform school work with greater speed. And the performance of adults was also shown to improve with higher ventilation rates

Wargocki, P., D.P. Wyon et al.

1999 & 2000

Increased outdoor ventilation rates and natural ventilation significantly reduces respiratory illness, flu’s and absenteeism by9-20%.

Fisk/LBNL 2000 as quoted by Vivian Loftness in Green Cities keynote address

Non-corrosive materials to accommodate harsh weather.


Easy to clean from inside the building.


Screening and security options available to secure buildings after hours.

Solar Control

When it comes to solar control, Altair Louvres:

  • Can achieve a Solar Heat Gain Coefficient between 0.2 and 0.72 using glass blades.
  • Can use timber or aluminium blades to completely block out the sunlight while still allowing maximum ventilation through the window.


Altair Louvre Windows provide tight sealing due to:

  • The patented living hinge design that prevents water and air penetration between the clips and the channels.
  • An over centre locking mechanism which applies strong locking pressure between blades when fully closed.

Thermal Insulation

Altair Louvre Windows can achieve low U-values. For example:

  • Altair Louvre Windows can achieve low U-values required for energy efficiency compliance/excellence (ranging from 2.5 to 6.9).
  • In extremely cold climates, louvre-fixed lite-louvre combination windows are a good way to achieve good ventilation and very low U-values.
  • Altair Louvres with metal mesh screens have WERS ratings available which significantly reduce the window’s U-value as the glass blades and the screen act in a similar way to double glazing.

Can Breezway Louvres be used with Mixed-Mode Cooling?

Breezway commissioned an independent study set in climate zone 5 (where 40% of Australia’s population is based) showed that by turning air conditioning off and using Altair Louvre Windows for cooling natural ventilation when appropriate had an annual air conditioning load decrease of 23%.

This far outweighs the benefits of sealing a building up tightly with fixed windows to improve the efficiency of air conditioning systems.
