What are the main types of windows available in Ontario, Canada?

The most common window types include casement windows, awning windows, hopper windows, sliding windows, double-hung windows, picture windows, and bay or bow windows.

Each is designed to solve a specific problem-whether you need better ventilation, more natural light, easier cleaning, maximizing energy efficiency, or a tighter seal against the wind.

Popular Window Styles for Ontario Homes 

Casement Windows: Best for Airflow & Energy Efficiency 

Casement windows are hinged on the side and open outward like a door. Because they open fully from top to bottom, they allow the most airflow into your home, making them the best option for ventilation.

They are also among the most energy-efficient windows because the sash presses firmly against the frame when closed, creating a tight, airtight seal.

Best for:

• Rooms that feel stuffy or need better airflow
• Hard-to-reach areas like over a kitchen sink
• Reducing drafts in cold rooms

Double-Hung Windows: Best for Easy Cleaning 

Double-hung windows are a traditional style where two sashes slide vertically. This allows you to open the window from the top, the bottom, or both.

The biggest advantage of modern double-hung windows is maintenance. Most are designed to tilt inward, so you can clean the outside glass from inside your room without ever needing a ladder.

Best for:

• Traditional or heritage-style homes
• Second-storey bedrooms for easy cleaning
• Rooms facing walkways where an outward-swinging window might be in the way

Sliding Windows: Best for Wide Openings 

Sliding windows move horizontally along a track. They are easy to use and generally have fewer moving parts than crank-style windows, making them very reliable over the long term.

Because they can be built in wider sizes, they are a practical choice for large openings where you want a clear view without a bulky frame in the middle.

Best for:

• Wide window openings
• Basement egress windows (emergency exits)
• Homeowners who want a simple, no-fuss design

Awning Windows: Best for Ventilation During Rain 

Awning windows are hinged at the top and open outward from the bottom. This design creates a small “roof” over the opening that keeps rain out while letting fresh air in.

Best for:

• Bathrooms or kitchens that need constant ventilation
• Maintaining privacy while the window is open
• Letting fresh air in even when it’s raining outside

Hopper Windows: Best for Basements & Compact Spaces

Hopper windows are hinged at the bottom and open inward from the top. They are compact, secure, and designed to improve airflow in smaller spaces.

Because of their shape and operation, hopper windows are commonly installed in basements, laundry rooms, and bathrooms where wall space is limited.

Their inward-opening design also helps create a tighter seal when closed, improving insulation and energy efficiency.

Best for:

• Basement window replacement
• Bathrooms and laundry rooms
• Small or narrow wall openings
• Improving ventilation in lower-level spaces

Picture Windows (Maximum Light and Efficiency)

Picture windows are “fixed,” meaning they do not open. Since they don’t have sashes that move, they are the most energy-efficient windows you can buy. They are purely designed to frame a view and bring in as much natural light as possible.

Best for:

• Living rooms with a view
• High or hard-to-reach spots where you only need light
• Maximizing insulation in rooms that already have other venting windows

Bay Windows & Bow Windows: Best for Expanding Views & Space

Bay and bow windows extend outward from the home, creating additional interior space and panoramic outdoor views.

These window styles increase natural light, improve curb appeal, and create a more open feel inside the home.

Best for:

• Living rooms and front-facing spaces
• Increasing natural light
• Enhancing curb appeal
• Creating additional seating or display space

How to Choose the Right Replacement Windows for Your Home 

The “best” window depends on the specific problem you are trying to fix.

• If your room feels cold: Go with casement windows. The way they lock into the frame creates the tightest seal against drafts.
• If you want to lower energy bills: Use a mix of picture windows (for maximum insulation) and casements (for airtight seals).
• If you struggle with cleaning: Choose double-hung windows. The tilt-in feature means you’ll never have to climb a ladder to clean your windows again.
• If you have an older home: Focus on custom-built windows. Older homes often have unusual sizes. A custom window is built to the exact millimetre of your opening, ensuring it actually seals properly and performs the way it should.
