If you’re planning a home upgrade or a window replacement in the Greater Toronto Area, chances are you’ve come across casement windows. These aren’t new to the Canadian market — in fact, they’ve been a favourite among homeowners for decades. But what makes them stand out? In this blog, we’ll walk you through what is a casement window, are casement windows better than other types, and give you a solid idea of how much casement windows cost in Canada.

Let’s clear the fog on one of the most practical window styles available today.

What is a Casement Window?

Simply put, a casement window is a side-hinged window that opens outward using a crank mechanism. Think of it as a mini-door for your wall — but for fresh air. Unlike sliders or hung windows that open vertically or horizontally along a track, casement windows swing out completely, allowing you to capture more breeze and natural light.

They’re built with energy efficiency in mind, thanks to their compression seal, which offers a tighter close than sliding models. That means fewer drafts, more consistent indoor temps, and lower heating bills — especially handy during our long Ontario winters.

At Polaris Windows and Doors, our casement window models are made with maintenance-free vinyl, multi-point locking systems, and fusion-welded corners for superior durability and security.

Key Features of Casement Windows

Casement windows come with features that serve both function and style. Here are some you’ll find in our most popular installations across the GTA:

• Crank handle for smooth operation

• Full swing-out design for better ventilation

• Energy Star rated glass with Low-E coating

• Triple-pane options for insulation

• Multi-point locks for security

• Noise reduction for a quieter home

• Custom sizing to fit heritage and modern homes alike

Because of these features, casement windows are often the go-to choice for homeowners who value practicality, comfort, and longevity.

Are Casement Windows Better Than Other Types?

This is the million-dollar question, and the answer depends on what you prioritize. But let’s break it down by comparing them to some common window styles.

1. Versus Sliding Windows

Sliding windows only open halfway and use brush seals, which can leak air over time. Casement windows open fully and use compression seals, offering better energy savings and a more complete breeze.

2. Versus Single or Double Hung Windows

Hung windows open vertically and are easier to break into if left unlocked. Casements are more secure with inside crank locks and tougher access from the outside.

• Single Hung Windows

• Double Hung Windows

3. Versus Awning Windows

Awning windows open upward, making them ideal for rain. Casement windows offer better cross-ventilation and a clearer view with larger glass panels.
