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.

Standard characteristics

Custom architectural windows

Flexible frame in the architectural window

It is possible to bend the thinner fixed monoblock frame of the architectural window into geometric shapes that will satisfy all tastes and styles. This type of frame is also used as a transom for doors and windows and offers a larger glass surface area thanks to its slimmed‑down frame.

Vaillancourt energy‑efficient glass (double or triple)

Energy‑efficient glass features a microscopic metallic coating. Additionally, an inert gas (argon) is inserted between the panes, which helps retain heat in winter and cool air in summer. Besides preventing condensation issues, energy‑efficient glass offers unmatched performance and substantial savings.

¹U 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.

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

³ER 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.
