Low Emissivity (Low E)

Low-emission glass is a clear glass with an ultra thin metallic coating.
  • Saves on energy costs, for both heating and cooling.
  • Reduces condensation
  • Reduces fading of interior furnishings, such as carpets, drapes and furniture

Triple Pane

Maximize energy savings while minimizing noise pollution and condensation. Three panes of glass are spaced apart and sealed to form a glazed unit with an air space between each glass.

Argon Gas

Clear, colourless and odourless, a naturally occurring gas.
  • Increases a windows ability to insulate. Because argon gas does not conduct heat as readily as air, it further reduces the heat transfer between the inside and the outside, helping to keep heat in during the winter and heat out in the summer.
  • Provides the real comfort benefit of increasing the temperature of the inner glazing. A warmer surface is much more comfortable to be near.
