ENERGY STAR Rated Casement Windows

Window Mart’s casement windows feature an excellent ENERGY STAR rating. They are made from 100% lead-free uPVC compound and boast a unique multi-chamber construction that boosts thermal performance.

What is a Casement Window?

Casement Windows are an attractive addition to any home, providing unparalleled ventilation and ease of operation. Commonly used in bathrooms or kitchens because of their ability to increase airflow, casement windows are hinged along one side. The main difference between casement and awning windows is the direction which they open, as awning windows are hinged along the top of the sash. With the simple turn of a handle, the supporting arm opens and closes casement windows to either the left or right. Casement windows conveniently open to 90 degrees, allowing for easy cleaning from inside or outside your home.  These windows also feature an excellent seal, which makes them one of the most energy efficient options on the market.

Window Mart casement windows are available in a wide array of colours, sizes, and configurations. We custom build every casement window to fit your home, complete with special features like window grills or custom hardware. At Window Mart we guarantee 100% customer satisfaction with our top-rated products and window installation services.

FAQs

What are casement windows and how do they open?

Casement windows are side-hinged windows that open outward with a crank handle, providing excellent ventilation and unobstructed views. This design maximizes airflow and usability compared to many other window styles.

Are casement windows energy efficient for Canadian climates?

Yes. Casement windows seal tightly around all sides when closed, reducing draft and heat loss — a key factor in energy performance for cold Alberta, Saskatchewan and Ontario winters or humid BC summers. They perform very well compared to other operable styles.

How do casement windows compare to fixed windows?

Casement: Offers ventilation and airflow control.

Fixed: Doesn’t open but can provide slightly higher overall insulation because there’s no operable sash.

Casement windows still deliver excellent insulation while letting you open them for fresh air

Are casement windows easy to clean and maintain?

Yes — the full-opening design lets you access both inside and outside glass from indoors in many installations. Regular cleaning of the crank mechanism and track helps maintain smooth operation.

Can casement windows improve home ventilation?

Absolutely — because they open fully outward, casement windows can capture breezes more effectively than other operable styles, improving airflow throughout your home.

How secure are your casement windows?

Yes — our casement windows use multi-point locking systems and tight compression seals that make them harder to force open than many sliders or hung windows.

Can casement windows be customized in size and style?

Yes — you can typically choose frame colours, grille patterns, and hardware finishes, and casement windows can be grouped or paired with fixed units for larger openings or design impact.

Can the casement windows qualify for energy rebates in Canada?

Yes — when they meet ENERGY STAR® Canada standards, casement windows may qualify for federal and provincial rebates. We can help evaluate eligibility based on your product choices and location.

How should I choose between casement and other window styles?

Ask yourself:
Is ventilation and airflow important?
Do you want maximum airtight performance?
Do outdoor clearance or room layout affect operation?
Our team can help you match style and performance to your home’s needs.

How do I clean the outside glass of a Casement window from the second floor?

You don’t need a ladder! Our modern Casement hinges are designed to open to a full 90 degrees and slide the sash slightly away from the frame. This creates a gap that allows you to reach your arm through and wipe the exterior glass safely from the inside of your home.
