Aluminum casement windows are hinged windows that open outward like a door, typically operated with a crank or handle. They are attached to the frame by one or more side hinges, allowing the window to swing open fully for maximum ventilation and easy cleaning.
Key Features:
- Excellent ventilation and unobstructed views
- Tight seal when closed, improving energy efficiency and sound insulation
- Durable aluminum frame, resistant to rust, warping, and weather
Aluminum casement windows are a popular choice for modern and minimalist designs due to their sleek profiles, strength, and low maintenance.
