Aluminum Casement Windows
Aluminum casement windows are a versatile and stylish choice for modern architecture. Hinged on the side and able to open outward or inward, they provide excellent ventilation, clear views, and a clean, timeless look suitable for both classic and contemporary spaces.
At Delanshini, each aluminum casement window is crafted with precision-engineered frames, premium hardware, and advanced sealing systems to ensure smooth operation, durability, and energy efficiency. Available in customizable sizes, colors, and glazing options, our windows bring the perfect combination of performance, comfort, and aesthetics to any residential or commercial project.
Advantages of Aluminum Casement Windows


Excellent Ventilation
Casement windows open fully outward, allowing maximum airflow into the room. This design captures side breezes effectively, improving indoor air circulation and comfort.


Energy Efficiency
When closed, the sash presses tightly against the frame, creating a superior seal that minimizes air leakage. Combined with thermal break profiles and insulated glass, this helps reduce heat transfer and energy costs.
Advantages of Aluminum Casement Windows


Durability and Low Maintenance
Aluminum is naturally resistant to rust, corrosion, and warping, making casement windows long-lasting even in harsh weather conditions. They require minimal upkeep—just occasional cleaning.


Modern Aesthetic Appeal
The slim aluminum frame offers a sleek and contemporary look that complements both residential and commercial designs. It allows for larger glass areas, maximizing natural light and outdoor views.


Smooth and Secure Operation
Equipped with high-quality hinges and multi-point locking systems, aluminum casement windows operate smoothly and provide enhanced security against forced entry.


Design Flexibility
Available in various colors, finishes, and opening configurations, aluminum casement windows can be customized to match architectural styles and individual preferences.

Top-Hinged Casement Window
Top-Hinged Casement Window is hinged at the top and open outward from the bottom. They are especially useful for ventilation even during rain, as the sash acts as a protective awning.

Casement Window Sizes
Standard Casement Window Sizes
There are no universal standard sizes for casement windows, as homes differ greatly in design, style, and age. However, manufacturers of pre-made windows typically offer a selection of commonly used sizes.While these standard sizes may not perfectly match every opening, they are generally close enough to allow installation with minor adjustments to the surrounding masonry or drywall.
Custom Casement Window Sizes
