What are casement windows?

A casement window is a side-hinged window that swings outward like a door and is typically operated with a crank handle for smooth opening and secure locking. Casement windows provide excellent ventilation and wide, unobstructed views, making them one of the most energy-efficient window styles available.

Ideal for both classic and contemporary homes, modern casement windows combine sleek design with high-performance insulation — a practical choice for Alberta’s changing seasons. Whether installed individually or in combination with fixed panes, they enhance natural light, airflow, and year-round comfort.

At Best Solution Windows and Doors, each casement window is ENERGY STAR® certified and custom-built to your home’s exact measurements for a seamless fit and long-lasting value. Proudly serving homeowners across Calgary, Edmonton, and nearby Alberta communities.

Casement windows styles

Single Casement Window

This design features a single sash that is hinged on one side and swings outward like a door. A single casement window is ideal for smaller rooms or tighter wall spaces, offering clean lines and effective airflow while maintaining a minimalist profile.

Double Casement Window

Double casement windows include two sashes hinged on opposite sides of the frame. When opened, they swing outward from the center, creating a wide, unobstructed opening. This style not only improves cross-ventilation but also enhances panoramic views, making it a favorite in living rooms and master bedrooms.

Triple Casement Window

Triple casement windows combine three independently operating sashes within one frame. This configuration delivers maximum flexibility in ventilation and daylight control, while maintaining a clean, symmetrical look. It’s especially useful in larger wall openings or for those looking to maximize energy efficiency.

Custom Casement Window

Custom casement windows are crafted to precisely match your desired dimensions, form, and aesthetic style. Whether you want arched tops, asymmetrical framing, or integrated grilles, this option offers full design freedom. Custom styles are perfect for blending architectural creativity with modern window performance.

Advatanges of Casement Windows

Energy Efficient

Casement windows are built with advanced materials and precision-sealed frames to reduce heat loss and minimize air leakage. As a result, insulation is enhanced, reducing energy costs and supporting stable indoor temperatures across all seasons.

Excellent Ventilation

Thanks to their full outward swing and flexible sash positioning, casement windows allow maximum airflow into your home. Even a slight opening captures passing breezes, making them an excellent choice for rooms that need better natural ventilation.

Security Features

Engineered with multi-point locking mechanisms and durable stainless-steel hardware, casement windows provide strong protection against forced entry. Their design ensures a tighter, more secure seal, giving you peace of mind without sacrificing style.

FAQ

How do casement windows open and operate?

Casement windows are mounted on side hinges and swing outward in the same way a door does. Most often, they are opened using a crank handle that provides smooth movement and secure closure. This outward-opening design allows for excellent ventilation and clear sightlines while maintaining energy efficiency.

Are casement windows suitable for small or narrow spaces?

Yes, casement windows work perfectly in tight or narrow areas. Their side-hinged mechanism allows the sash to fully open outward, making the most of limited space while still offering strong airflow, natural light, and ease of use.

Can casement windows be installed in combination with other window types?

Absolutely. Casement windows can be combined with fixed, picture, or even bay and bow windows to create a custom look and meet specific performance needs. Whether you want to increase ventilation, expand your view, or enhance curb appeal, they integrate seamlessly with other styles.

What kind of security features do your casement windows have?

Casement windows from Best Solution Windows and Doors feature multi-point locking systems and tight-sealing frames for enhanced security. Their design prevents forced entry when closed, offering peace of mind without compromising on ventilation or aesthetics.

What makes modern casement windows different from traditional designs?

Modern casement windows are engineered with advanced materials and performance upgrades. Compared to traditional models, they feature slimmer frames, improved thermal insulation, and cleaner sightlines. At Best Solution Windows and Doors, our modern casement windows come with ENERGY STAR® certification, multi-point locks, and customizable finishes to match today’s design trends and energy efficiency standards.

What should I consider before starting a casement window replacement?

Before starting a casement window replacement, consider your home’s layout, ventilation needs, and style preferences. Casement windows are great for areas that benefit from full airflow, natural light, and clear outdoor views. It’s also important to assess your current window openings and desired features. Our project managers will guide you through sizing, configurations, and finishing options to ensure your new windows match both your home and your budget.
