Why we love architectural windows

Custom shapes & styles

Dare to be original! With our architectural windows, you can choose the geometric shape you want: with its one-piece frame, thinner than our other models, it can be bent to your measurements. It's your chance to stand out from other homes in your neighbourhood.

Incomparable lighting

Use architectural windows alone or combined with any other window models to adjust glass surface and make your living space even brighter.

A touch of elegance

Without a doubt, architectural windows add a unique touch to your home with their distinctive, antique look. They also fit well with contemporary or country-style homes, depending on the shape you give them.

Vaillancourt energy efficient glass (double or triple)

Our energy efficient glass is equipped with a microscopic metallic film. In addition, an inert gas (argon) is added between the glass panels to preserve interior heat in winter and coolness in summer.

More than just helping relieve condensation issues, energy efficient glass offers unmatched performance and substantial savings.

Standard characteristics

Flexible frame in the architectural window

The thinner, fixed one-piece frame in architectural windows can be bent to form geometric shapes that will satisfy all tastes and styles. This type of frame is also used for transom windows in doors and windows to allow more glass surface due to its thin frame.

1 U factor – W/m2-K (Btu/h ft2-F): Indicates the rate of a material's transfer of heat. The lower the U factor, the higher the window's performance.

2 Solar Heat Gain Coefficient (SHGC): Indicates the solar energy that can pass through the window. The higher the coefficient, the higher the window's performance.

3 ER factor: Indicates a window's global energy efficiency. The higher the ER factor, the higher the window's performance.

R factor: Indicates the degree of resistance in a material's temperature transfer. The higher the R factor, the higher the window's performance.
