Natural Ventilation and Altair® Louvre Window: A perfect match for healthy living

Natural ventilation is crucial for maintaining the quality of indoor air in any environment. It not only helps to keep the air we breathe clean and fresh but also allows us to stay connected to nature. In addition, it can significantly reduce our energy expenses.

Over the years, Louvre Windows have undergone significant changes since they first appeared in the late 1930s. Despite these changes, they remain a popular and functional choice for windows. Breezway Altair Louvre Windows, in particular, have a unique design that allows them to open twice as wide as other window types. This design feature provides maximum ventilation and enables a natural cooling effect in living or working spaces without the need for artificial air conditioning systems.
