Standard Features

  • Welded frame corners prevent leaks, adds strength and keeps window square
  • Thermal pane glass insulates against noise
  • 4 1/2" welded vinyl frame complete with a built-in 3/4" return ready to accept the interior finish of your choice

Energy Efficiency

  • Double glazed, sealed unit with 5/8" air space for insulation
  • "Low E" glass or "Low E" argon gas-filled for better insulation (optional)
  • Multi-chamber design for optimum insulation and strength
  • Triple glazing available as an option

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.


Translucent pebbly finish that allows light in but obscures view for privacy. Most often used in bathrooms.

Grey or Bronze Tint

Glue Chip

Transparent and colourless. A lovely fern-like pattern on one surface, resembles a window after a visit from Jack Frost. Makes a pleasant background for any window.

Acid Etch
