From single-sash units to multi-panel combinations, aluminum casement windows offer flexible configurations for both residential and commercial applications.
Single Casement Window
A single casement window consists of one operable sash hinged on the side of the frame. It is commonly used for smaller openings where simple operation and effective ventilation are required. Single casement windows are often installed in kitchens, bathrooms, and compact living spaces.
Double Casement Window
Double casement windows feature two operable sashes within one frame, typically opening from the center. Also referred to as a twin casement window or double swing window, this configuration allows wider openings, improved airflow, and balanced appearance, making it suitable for larger window openings and living areas.
Triple Casement Windows
Triple casement windows, also known as 3 lite casement windows, combine three panels within a single window unit. The side panels are usually operable casement sashes, while the center panel may be operable or fixed depending on design requirements. This layout is ideal for wide openings where ventilation and panoramic views are both desired.
Thermal-Break Casement Window
Thermal-break aluminum casement windows consist of two separate aluminum profiles connected by a high-performance PA66 thermal insulation strip. This structure allows for different surface treatments inside and outside the frame. The exterior aluminum profile can be customized to complement the building’s façade, while the interior profile can match the room’s interior design, making it highly versatile for modern architecture.
PA66 Insulation Strip: The high-performance PA66 insulation strip breaks the thermal bridge, reducing the transfer of heat or cold through the aluminum frame.
Enhanced Thermal Insulation: The combination of the thermal break and double-glazed glass ensures outstanding energy efficiency for both hot and cold climates.
Excellent Sound Insulation: With the insulating strip and insulated glass, the window provides superior noise reduction, creating a quieter indoor environment.
