Aluminum casement windows have carved out a significant niche in the world of window designs, being a popular choice across various building types. These windows are characterized by their hinged installation on one side of the window sash, which is then connected to the window frame. Based on the direction of opening, they are classified into external casement windows and internal casement windows. This type of window has a simple yet effective structure, allowing for flexible opening mechanisms. It also offers easy cleaning access and provides excellent sealing performance when closed, making it one of the most widely utilized window types in civil buildings.

Main Features

Opening Methods

Inward Opening

Inward - opening aluminum casement windows offer the distinct advantage of being extremely easy to clean. Homeowners can simply reach out from inside the room to wipe down the window panes, eliminating the need for potentially dangerous exterior cleaning, especially in multi - story buildings. However, a drawback of this opening method is that it occupies indoor space when opened. In smaller rooms, this can be a significant consideration as it may impede furniture placement or movement within the room. For example, in a compact urban apartment with limited floor space, an inward - opening casement window might restrict the area available for placing a bookshelf or a small table near the window.

Outward Opening

Outward - opening casement windows are highly valued for their space - saving design. They do not intrude into the indoor area when opened, which is ideal for rooms where space is at a premium. This makes them a popular choice for living rooms, bedrooms, and even commercial spaces such as offices. However, in high - rise buildings, special attention must be paid to wind resistance. Strong winds can put significant stress on outward - opening windows, and proper engineering and installation techniques are required to ensure their safety. In a high - rise building in a windy coastal area, for instance, outward - opening aluminum casement windows need to be designed with reinforced frames and high - quality hinges to withstand the powerful gusts.

Tilt & Turn (Top - hung)

The tilt & turn or top - hung variant of aluminum casement windows is a versatile option, particularly well - suited for high - rise buildings. This type of window allows for a slight tilt, which provides ventilation while also offering rain protection. The tilt angle can be adjusted to control the amount of air flow, and even during light rain, the window can be left tilted to let in fresh air without water entering the room. Additionally, the tilt & turn mechanism enhances security as the window can be set to a partially open position that is difficult to breach. In a luxury high - rise condominium, tilt & turn aluminum casement windows not only add a touch of elegance but also provide a practical solution for residents to enjoy fresh air while maintaining safety and protection from the elements.

Structural Components

Frame + Sash

The frame and sash of aluminum casement windows are constructed from high - strength aluminum alloy profiles. These profiles offer excellent durability, being resistant to corrosion, rust, and warping. In areas with high humidity or near coastal regions, such as the Gulf Coast in the United States or the tropical islands, aluminum alloy profiles are highly suitable as they can withstand the harsh environmental conditions. An optional thermal break design is available for those seeking enhanced insulation. Thermal breaks, usually made of materials like polyurethane or nylon, are inserted between the inner and outer parts of the aluminum frame. This design significantly reduces heat transfer, making the window more energy - efficient. In colder climates, buildings with aluminum casement windows featuring thermal breaks can experience lower heating costs as the heat is retained within the building more effectively.

Hardware

The hardware components of aluminum casement windows, including hinges, handles, and locking points, play a crucial role in the window's performance. High - quality hinges are essential for smooth and reliable opening and closing of the window. They need to support the weight of the sash over an extended period without sagging or malfunctioning. Handles are designed for easy operation, and their ergonomic design can enhance the user experience. Locking points are vital for security, and multiple locking points can be installed to provide better protection against break - ins. The quality of the hardware also impacts the sealing performance of the window. Well - fitted hardware ensures that the window closes tightly, preventing air and water leakage. In a commercial building where security and energy efficiency are top priorities, investing in high - end hardware for aluminum casement windows is a wise decision.

Glass

Aluminum casement windows are typically equipped with either insulated glass or laminated glass, depending on the requirements. Insulated glass, which consists of two or more glass panes separated by a spacer filled with air or an inert gas like argon, offers excellent sound and thermal insulation. It helps in reducing outside noise, creating a quieter indoor environment. In urban areas with high traffic or near industrial zones, buildings with insulated glass in their aluminum casement windows can provide a more peaceful living or working space. Laminated glass, on the other hand, is prized for its safety features. It is made by bonding two or more layers of glass together with a plastic interlayer. In the event of an impact, the plastic interlayer holds the glass pieces together, preventing them from shattering and causing injury. This makes laminated glass a suitable choice for areas where safety is a concern, such as in schools or in buildings located in earthquake - prone regions.

Sealing Performance

Aluminum casement windows utilize multi - layer sealing strips, which give them a significant edge in terms of sealing performance compared to sliding windows. These sealing strips are made of materials like rubber or silicone, which are flexible yet durable. The multi - layer design creates a tight seal around the window sash when it is closed. This results in superior windproof capabilities, ensuring that strong winds do not force air into the building, which could otherwise cause drafts and increase energy consumption. In terms of waterproofing, the tight seal prevents rainwater from seeping through the window joints, protecting the interior of the building from water damage. Additionally, the excellent sealing also contributes to better soundproofing. In a building located near a busy airport or a major highway, aluminum casement windows with multi - layer sealing strips can effectively reduce the amount of noise that enters the building, creating a more comfortable and quiet environment.
