Why we love sliding windows

As affordable as they are durable

Our sliding windows are our model with the least hardware, making them the most affordable and with the least long-term risk of breakage. In spite of simple construction, they are also more durable than other models.

They open gently

The panes open easily due to the simple and efficient tandem roller system integrated in our sliding windows. The nylon rollers are integrated under the moveable panes.

Flexible & versatile

You have many choices of configurations with sliding windows, whether single or double. They can be used in confined spaces such as apartments or basements. The tilt latch system on the panes also allows them to be clean from the exterior or interior.

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

Roller system for gentle sliding

Gentle sliding is guaranteed with our simple and efficient tandem roller system with integrated nylon rollers under moveable panes. Unlike other window systems, the limited amount of hardware parts gives this window an economic advantage and reduce long-term risk of breakage without compromising quality and durability.

Lock & practical tilt latch

The sliding window lock system combined with an integrated, aesthetically pleasing tilt latch system allows panes to tilt easily. With the help of buttons on each end, cleaning your windows from the inside is easy, too.

Strong screen

Screens offer a simple mounting system that is easy to clean. Manufactured in fiberglass, they are strong and tight. Screen frames are made of enamelled aluminium.

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.
