Many people underestimate the role of the window frame in energy efficient home design. Without windows our homes would be dark and uninviting. Windows play a critical role in your home’s comfort and energy consumption. They set the tone of your home by providing daylight, views, ventilation and a sense of spaciousness.

The use of modern performance glass and the thermal break technology in Dowell ThermaLine™ allows the home owner to have large windows while delivering outstanding energy efficiency and comfort. In fact, the most energy efficient windows result from a combination of both an insulated frame and the right glass to achieve superior energy performance.

Dowell ThermaLine™ windows have been rated as the most energy efficient thermally broken aluminium windows on the Australian residential market today, based on a glass to glass comparison*.
