Warm sunlight flooding through a window is great when it’s cold, however normal windows allow most of this heat to leak right back out of the building.

Altair louvre windows by Breezway are available with clear glass blades with a microscopic layer of metallic oxide, or Low e glass, thin enough to be invisible to the naked eye, but thick enough to improve the insulating properties of the glass.

The result of this louvre window technology is sunlight streaming into the home and staying there, as the louvre window's insulation becomes comparable to that of a double glazed window, all without compromising views.
