What Are Hybrid Windows? Steel-Reinforced Windows Explained

If you are shopping for replacement windows in the GTA, you may have heard of hybrid windows. They combine the insulation of vinyl with the strength of metal. Here is what they are, how they compare with standard vinyl, and whether they are right for your home.

Window & Door Specialist has supplied and installed replacement windows in the GTA since 1985, and hybrid windows are now one of our most requested upgrades.

What Are Hybrid Windows?

A hybrid window has a vinyl (uPVC) frame with a steel and aluminum skeleton inside. The vinyl outside insulates and resists weather. The metal core adds strength and keeps the frame straight and stable over time.

Hybrid vs Standard Vinyl Windows

Benefits of Hybrid Windows

• Strength: the reinforced core resists bending, warping and sagging.
• Stability in Canadian weather: holds its shape through hot summers and cold winters.
• Security: a stronger frame supports multi-point locking.
• Quiet: multi-pane glass options help reduce outside noise.
• Low maintenance: no painting, like vinyl.

Security is a priority? Pair hybrid frames with laminated security glass.
