In the realm of modern architecture, windows are not merely openings in the walls but integral components that contribute significantly to a building's aesthetics, functionality, and energy efficiency. Among the diverse range of window options available, aluminum alloy fixed windows stand out as a popular choice for various construction projects. These windows, characterized by their fixed sashes that remain immovable, offer a unique set of advantages that make them suitable for a wide array of applications.

 Main Features

 High Light Transmittance

One of the most prominent features of aluminum fixed windows is their exceptional light transmittance. With no opening sashes to obstruct the view, these windows provide an unhindered and expansive field of vision. This makes them an ideal choice for large-area glass designs, such as those found in contemporary office buildings, luxury residences, and public spaces. The absence of moving parts allows for a seamless expanse of glass, maximizing the amount of natural light that floods into the interior. In a residential living room, an aluminum fixed window can transform the space, making it feel more open, airy, and inviting. The sunlight streaming through not only brightens the room but also has a positive impact on the occupants' mood and well-being. In commercial settings, such as retail stores or restaurants, the high light transmittance can enhance the display of products or create an attractive ambiance for customers.

 Strong Sealing

Aluminum fixed windows excel in terms of sealing properties. Since they lack moving parts, they inherently offer better air tightness and water tightness compared to openable windows. This is particularly crucial in regions with varying weather conditions. In areas prone to strong winds and heavy rainfall, the tight seal of fixed windows effectively prevents air leakage and water seepage. The airtight nature of these windows helps to maintain a stable indoor temperature, reducing the need for excessive heating or cooling. This not only contributes to energy savings but also ensures a more comfortable living or working environment. In addition, the excellent wind and dustproof effect of aluminum fixed windows keep the interior free from dust and debris, reducing the frequency of cleaning and maintenance.

 Stable Structure

The stable structure of aluminum fixed windows is another significant advantage. Without the wear and tear associated with hardware components in openable windows, these fixed windows have a longer service life. The absence of hinges, locks, and other moving parts means there is less likelihood of mechanical failures. This reliability is especially valuable in large-scale construction projects where the replacement or repair of windows can be costly and time-consuming. In high-rise buildings, for example, aluminum fixed windows provide a durable and low-maintenance solution. Their robust construction can withstand the test of time, even in harsh environmental conditions. The low maintenance cost associated with fixed windows is also appealing to property owners, as it reduces long-term expenses and allows for more efficient property management.

 Flexible Design

Aluminum fixed windows offer remarkable design flexibility. They can be customized to fit virtually any size or shape requirement. For projects that demand extra-large windows, these can be fabricated with the use of tempered or laminated glass to enhance safety. The ability to create oversized fixed windows is particularly beneficial for creating dramatic visual effects. In a penthouse apartment, an extra-large aluminum fixed window can provide a breathtaking panoramic view of the city skyline. Architects and designers can also play with different shapes, such as circular or arched fixed windows, to add a touch of uniqueness to a building's facade. This design flexibility allows for seamless integration with various architectural styles, from modern and minimalist to traditional and ornate.

 Energy Saving and Environmental Protection

When equipped with insulated or Low-E (low-emissivity) glass, aluminum fixed windows exhibit excellent thermal insulation performance. Insulated glass consists of multiple panes of glass with an air or gas-filled space in between, which acts as a barrier to heat transfer. Low-E glass, on the other hand, has a special coating that reflects heat back into the room during winter and blocks the sun's heat in the summer. In cold climates, the thermal insulation properties of these windows help to keep the warm air inside the building, reducing the reliance on heating systems. In warmer regions, they prevent the ingress of excessive heat, minimizing the need for air conditioning. By contributing to energy conservation, aluminum fixed windows not only benefit the building occupants in terms of reduced utility bills but also play a role in environmental protection by lowering overall energy consumption.

 50 & 55 Series

 Series

The 50 series non-thermal break and 55 series thermal break aluminum fixed windows offer distinct features tailored to different needs. The 50 series non-thermal break windows are a cost-effective option for projects where thermal performance is not the primary concern. They are suitable for areas with relatively mild climates or in applications where the focus is more on basic functionality and aesthetics. The 55 series thermal break windows, on the other hand, are designed to provide enhanced thermal insulation. The thermal break feature, which involves the use of a non-conductive material (such as nylon or polyamide) to separate the interior and exterior aluminum profiles, reduces heat transfer through the frame. This makes the 55 series an ideal choice for regions with more extreme temperature variations.

 Profile Thickness

Both the 50 and 55 series come with profile thickness options of 1.4/1.6mm. The choice of profile thickness depends on factors such as the size of the window, the expected wind loads, and the desired level of structural integrity. A 1.4mm profile thickness may be sufficient for smaller windows or in areas with lower wind pressures, while a 1.6mm thickness offers added strength and durability for larger installations or more challenging environmental conditions. The profile thickness also contributes to the overall appearance of the window, with a thicker profile often giving a more substantial and robust look.

 Glass Notch

With a glass notch of 23mm, these series are designed to accommodate a specific glass configuration. The recommended glass for both the 50 and 55 series is 5+12A+5mm. This combination consists of two 5mm thick glass panes separated by a 12mm air gap (denoted by 'A'). The air gap acts as an additional layer of insulation, further improving the thermal performance of the window. The 5+12A+5mm glass configuration strikes a balance between cost and energy efficiency, making it a popular choice for a wide range of applications.

 Window Type

As part of the fixed window category, both the 50 and 55 series offer a static window solution. Fixed windows in these series are primarily used for their light transmission and aesthetic qualities. They can be installed as individual units or combined to create larger glass expanses.
