Casement Windows 101: How They Work and Why Homeowners Love Them
Casement windows are a classic and highly practical window style, designed to offer wide-open ventilation and energy efficiency in one sleek package.
Unlike sliding windows, casements are attached to the frame by one or more side hinges and swing outward — much like a door — when you turn a crank handle.
Their design makes them incredibly user-friendly, especially in areas where traditional windows are harder to operate. A quick turn of the handle smoothly opens the sash outward, letting in fresh air from top to bottom.
Typical Features of Casement Windows:
Today’s casement windows still carry that traditional charm but have been vastly modernized with advanced materials, tight weather seals, and energy-efficient glazing — making them perfect for today’s homes, especially in challenging climates like Ottawa as highlighted in the Efficient Windows Collaborative’s guide to window types.

Typical Features of Casement Windows:
-
Shape and Proportion: Casement windows are usually taller than they are wide, giving a clean, vertical line that complements many architectural styles.
-
Installation Style: They can be installed as single windows or paired together in one frame, often cranking outward in opposite directions to maximize air circulation.
-
Usage Hotspots: Casements are a popular choice for:
-
Above kitchen sinks — where the crank mechanism makes opening easy even at awkward reaches.
-
Main floor living rooms and bedrooms — offering unobstructed views and excellent ventilation.
-
Upper floor bedrooms — prized for their wide openings and easy operation, especially for meeting modern egress (emergency exit) requirements.
-
Above kitchen sinks — where the crank mechanism makes opening easy even at awkward reaches.

Key Benefits of Casement Windows for Ottawa Homes
Casement windows aren't just stylish — they deliver a powerful combination of ventilation, energy efficiency, security, and ease of use, making them one of the smartest window upgrades for Ottawa homeowners.
Here’s why casement windows are so popular:
1. Excellent Ventilation: A Breath of Fresh Air
Casement windows open fully outward, allowing homeowners to catch side breezes and funnel fresh air directly into their homes.
In Ottawa’s crisp spring and fall seasons, a casement angled toward the wind acts almost like a sail, directing refreshing breezes indoors.
It’s no surprise they’re often called “a breath of fresh air” for living spaces, helping keep homes naturally cooler and better ventilated.
2. Superior Energy Efficiency: Seal Out Ottawa Winters
When closed, casement windows latch tightly, pressing the sash firmly against the frame’s weatherstripping to create an airtight seal.
This design results in lower air leakage rates than sliding or hung windows, making casements one of the top choices for energy-conscious homeowners (source).
In Ottawa’s harsh winters, this tighter seal helps reduce drafts, improves indoor comfort, and cuts heating costs.
In fact, research from the Efficient Windows Collaborative highlights that casement and awning windows generally outperform other types in terms of thermal efficiency.
3. Easy Operation & Maintenance: Effortless Everyday Use
With a simple crank handle, casement windows are easy to operate for people of all ages and mobility levels.
No lifting or pushing — just an easy turn of the wrist. This makes them ideal for:
- Seniors
- People with limited arm strength
-
Hard-to-reach spots like over kitchen sinks
4. Great Views & Abundant Natural Light
Unlike double-hung or sliding windows that often have a horizontal or vertical sash interrupting the view, casement windows offer a wide, unobstructed pane of glass.
This makes rooms feel brighter, larger, and more connected to the outdoors — whether you're admiring a lush summer garden or a snowy Ottawa backyard.
Fewer obstructions mean more natural light, which can boost mood, productivity, and even home value.
5. Enhanced Security: Peace of Mind Built In
Casement windows are known for excellent security thanks to their embedded locking systems.
Most models feature multi-point locks that engage at several points along the frame when cranked shut, making them extremely difficult to pry open from the outside.
Plus, because the entire sash swings outward, casement windows can also double as an emergency exit (egress window) if sized and installed correctly — an important feature for basement bedrooms or upstairs rooms.
Casement Windows and Egress Requirements in
Ottawa Homes
When planning a basement renovation or adding a bedroom in Ottawa, one critical safety feature you must consider is egress windows.
An egress window is a window large enough for a person to escape through during an emergency — and large enough for a firefighter wearing gear to enter.
According to the Ontario Association of Fire Chiefs, Ontario’s fire code requires that all bedrooms — especially in basements — must have an egress window that meets minimum size standards for safe exit and rescue access.

Why Casement Windows Are Ideal for Egress
Casement windows are one of the best window styles for meeting egress requirements.
Unlike sliding or double-hung windows, a casement swings fully outward, offering a clear, unobstructed opening without any center bar or sash blocking the way.
Even relatively small casement windows can qualify, because they allow access to nearly 100% of the frame size, whereas sliders and double-hung windows typically only open about 50%.
In Canada, the required clear opening for an egress window is typically at least 0.35 square meters (3.77 square feet), with no dimension less than 15 inches (source).
Choosing casement windows not only enhances safety but also improves overall home ventilation and energy efficiency, as emphasized by the Efficient Windows Collaborative.

Casement Windows: A Smart Choice for Ottawa's Climate
Beyond meeting safety codes, casement windows are an outstanding choice for Ottawa homes due to their energy-efficient design.
When closed, the sash presses tightly against weatherstripping, creating an airtight seal that minimizes heat loss — critical during Ottawa’s long winters.
According to the U.S. Department of Energy, casement windows typically outperform sliders and hung windows when it comes to preventing drafts and lowering energy costs.
For additional assurance, choosing ENERGY STAR–certified windows ensures your new installation meets top standards for thermal performance and insulation.
When selecting windows for your renovation, it’s important to think not just about appearance — but also about functionality, safety, and energy performance. The Canada Mortgage and Housing Corporation (CMHC) recommends carefully considering window upgrades as part of any home improvement project for long-term energy savings.

Comparing Casement Windows to Other Window Types
Choosing the right window style for your home isn’t just about looks — it’s also about energy efficiency, ventilation, and practical functionality, especially in Ottawa’s challenging climate.
Here’s how casement windows stack up against other common window types:
Casement Windows vs. Sliding Windows
-
Casement windows open outward with a crank, while sliding windows move horizontally along a track.
-
Energy Efficiency: Casements generally provide a tighter seal against drafts. According to the U.S. Department of Energy, sliding windows often have higher air leakage rates due to gaps in their sliding tracks, while casements compress tightly against weatherstripping when closed.
-
Space Considerations: Sliders don't project outward, making them ideal for areas along narrow walkways or patios.
-
Egress Situations: While casements are often better for airtightness, sliding windows can still be a good fit for wide but short openings — such as some basement egress windows.
For Ottawa's cold winters and high-efficiency needs, casements generally outperform sliders in keeping cold air out.
Casement Windows vs. Double-Hung Windows
-
Double-hung windows open by sliding vertically, while casements crank outward.
-
Energy Efficiency: Double-hung windows traditionally allow more air leakage compared to casements, which offer a full compression seal (Efficient Windows Collaborative).
-
Ventilation: Only half of a double-hung window opens for air, whereas casements allow full top-to-bottom ventilation.
-
Aesthetic and Space: Double-hungs provide a classic, traditional look and do not swing out over decks or walkways — ideal where exterior swing space is limited.
Casements offer better ventilation and modern styling, but double-hungs may suit locations where outward swing would interfere.
Casement Windows vs. Awning Windows
-
Awning windows are essentially casement windows rotated 90°, hinged at the top instead of the side.
-
Energy Efficiency: Both styles offer similar superior sealing against drafts (ENERGY STAR Canada).
-
Weather Performance: Awnings excel at allowing ventilation even during rain, as the sash sheds water away from the home.
-
Airflow Direction: Casements are better for catching side breezes, while awnings mostly vent upward.
-
Design Tip: Many Ottawa homeowners combine both — using casements for large windows and awnings for smaller spaces or above/below picture windows.
Both are excellent choices; it depends whether you prioritize side breezes or rain-protected airflow.
