Vinyl windows are one of the most popular choices for homeowners in Canada, known for their durability, energy efficiency, and relatively low maintenance. Behind every window, however, there is a carefully engineered process that brings together raw materials, custom manufacturing, precision glass, and advanced hardware.
From Raw Materials to Extrusions
The process begins with polyvinyl chloride, better known as PVC. This plastic compound is blended with stabilizers, impact modifiers, and colorants to create a formulation suited for long-term performance in Canada’s climate. The result is a durable material that resists fading, warping, and cracking even after years of exposure to harsh winters and hot summers.
Once the PVC compound is prepared, it is heated and forced through a die in a process known as extrusion. These extrusions are the building blocks of vinyl window frames and sashes. Every window manufacturer works with extrusion suppliers who shape the profiles to match their own specifications. This means the design, thickness, and chamber structure inside each profile can be customized for strength, insulation, and aesthetics. In other words, while vinyl windows may look similar on the surface, the internal engineering often varies from one company to another.
The Glass: A Canadian Standard
No window is complete without glass, and in Canada, most residential glass comes from two primary manufacturers: Cardinal Glass and Guardian Glass. These industry leaders supply the insulated glass units (IGUs) that provide energy efficiency, noise reduction, and security. Their glass products are often coated with specialized low-emissivity (Low-E) coatings, which help regulate indoor temperatures by reflecting heat back inside during the winter and blocking excess heat in the summer.
By sourcing from Cardinal and Guardian, Canadian window companies ensure consistent quality and performance that meets or exceeds national energy efficiency standards.
Hardware: The Details that Matter
The final element of a high-performing vinyl window is its hardware. Components such as locks, hinges, and operators may not always be the first thing a homeowner thinks about, but they are critical for both functionality and security. At Interlink Doors & Windows, hardware is sourced from Assa Abloy, a global leader in access solutions. Their reputation for precision engineering and durability ensures that every window not only operates smoothly but also provides long-lasting protection.
Bringing It All Together
From the raw PVC extrusions to the glass sealed units and precision hardware, the manufacturing of vinyl windows is a coordinated process that combines chemistry, engineering, and craftsmanship. Each element is selected and designed to withstand Canadian conditions while providing homeowners with comfort, style, and peace of mind.
