Aluminum Alloy

The primary material used in the construction of aluminum fixed glass windows is aluminum alloy. Aluminum alloys are created by combining aluminum with other elements, such as magnesium, silicon, copper, or zinc, to enhance specific properties. For window applications, alloys are selected for their high strength - to - weight ratio, which allows for the support of large and heavy glass panes without adding excessive weight to the building structure.

Aluminum alloys also offer excellent corrosion resistance. When exposed to air, aluminum forms a thin, protective oxide layer on its surface, which prevents further oxidation. This natural self - healing property makes aluminum windows highly durable and suitable for various environmental conditions, from coastal areas with high humidity and salt exposure to regions with extreme temperature fluctuations.

 Surface Treatments

To further enhance the durability and aesthetic appeal of aluminum fixed glass windows, various surface treatments are applied. Anodizing is a popular treatment method that involves an electrochemical process to thicken the natural oxide layer on the aluminum surface. This anodized layer not only provides superior corrosion resistance but also gives the aluminum a sleek, uniform appearance. Anodized aluminum can be left in its natural metallic finish or dyed in a range of colors to match the building’s exterior or interior design.

Powder coating is another widely used surface treatment. In this process, a dry powder is applied to the aluminum surface and then cured under heat, creating a hard, durable, and colorful finish. Powder - coated aluminum windows are highly resistant to scratches, chips, and fading, making them ideal for both residential and commercial applications. The vast array of colors and textures available through powder coating allows for extensive customization to meet the specific design requirements of any project.

 Sealants and Adhesives

Sealants and adhesives play a crucial role in the construction of aluminum fixed glass windows. High - quality sealants are used to create a watertight and airtight seal between the glass and the aluminum frame. These sealants are typically made of materials such as silicone or polyurethane, which are flexible, durable, and resistant to weathering. The sealant not only prevents water infiltration but also helps to isolate the glass from the frame, reducing the transmission of vibrations and noise.

Adhesives are used to bond the glass to the frame, providing additional structural support. Structural glazing adhesives are specifically designed for this purpose, offering high strength and durability. They allow for the creation of frameless or minimal - frame fixed glass windows, where the glass appears to be floating without visible frames, creating a modern and sleek aesthetic.
