Window Technology

Using multiple glazings, innovative coatings and insulating spacers, windows used in Super E® homes improve on virtually every aspect of traditional windows, to provide:

Lower heating costs
More natural light
Minimal noise from outdoors
Reduces condensation and draughts
Low-e coatings reduce fading of furniture and carpets
Greater living comfort overall

Windows are a key feature of every Super E® home. Windows in Super E® homes have at least two layers of glass, making them resistance to heat loss and outside noise.

Each glass layer is separated by an air space to provide insulation. Some windows fill the air space with inert gas, such as argon gas, which makes the window even more resistant to heat loss and noise transmission.

Insulating spacers also separates the layers of glass. Many windows in non-Super E® homes do not provide an effective insulating spacer, allowing heat to be lost through the window frame.

Most windows in Super E® homes also have a low-e coating. “Low-e” stands for low-emissivity. This thin coating reduces the amount of heat radiated, helping keep the inside cool in the summer and warm in the winter. Although the low-e coating is transparent, it also helps reduce fading of carpets and furniture by cutting the intensity of the sun’s rays.

All Super E® windows must pass stringent tests for air tightness, water tightness, wind load resistance and ease of operation.
