Silex Windows and Doors

Canadian Craftsmanship, Unmatched Performance

About Our Name

Our name, Silex, is rooted in the very essence of our products. It comes from the Latin word for “silica,” the chemical foundation of window frames and glass. Silica’s natural complexity resonates with our commitment to innovation. We recognize its potential in its various forms, both natural and synthetic, to create windows and glass that are not only beautiful but also remarkably durable.

Choosing Silex reflects our dedication to building upon a strong foundation. Just as silica forms the base for countless natural wonders, it provides the core for our high-quality window and glass solutions. We are committed to crafting products that stand the test of time, much like the enduring presence of silica throughout our planet’s history.

Our Advantage

Environmentally Friendly

Fiberglass Strings are made mostly from silica sand (sustainable natural resource), the lineal manufacture process consume the least embodied energy when compared to other common window frame materials such as Aluminum and PVC.

Low Maintenance

Fiberglass is the most stable material in virtually unlimited colors and an interior wood veneers. The maintenance-free frames stay true to form due to strength of materials. No need for sanding, painting, or staining.

Low Thermal Conductivity / Energy Efficient

Pultruded Fiberglass profile insulates better than any of the traditional window and door materials. The thermal conductibility ratio is 500x less than aluminum. Insulating the frame and sash components reduces the conductivity even further, allowing for the creation of some of the most energy efficient window and door systems.
