What are the advantages of the frame material of aluminum sliding windows for home and how are their water tightness and air tightness?

Advantages of the frame material of aluminum sliding windows for home:
Lightweight and high strength: Aluminum alloy material, with its low density and high strength, makes the window frame lighter and easier to install and transport while ensuring structural stability.
Strong corrosion resistance: Aluminum alloy has good corrosion resistance. Even in humid or harsh climatic conditions, aluminum alloy sliding windows can maintain the integrity and beauty of the window frame and extend its service life.
Easy to process and maintain: Aluminum alloy material is easy to cut, bend and weld, making it easy to make window frames of various shapes and sizes. At the same time, its surface is smooth, not easy to accumulate dust, and cleaning and maintenance are relatively simple.
Good thermal insulation performance: Although aluminum alloy itself has good thermal conductivity, reasonable thermal insulation design and treatment, such as the use of broken bridge insulation technology, can effectively reduce heat transfer and improve the thermal insulation performance of windows.
Environmentally friendly and recyclable: Aluminum alloy is a recyclable material that conforms to the concept of modern green buildings and helps reduce resource waste and environmental pollution.

Water tightness and air tightness of aluminum alloy sliding windows for home:
Good water tightness: When designing aluminum alloy sliding windows, sealing strips or sealants are usually set between the window frame and the window sash to ensure that the window can effectively prevent rain penetration when closed. This design allows the window to maintain good waterproof performance even on rainy days to prevent indoor moisture.
Strong air tightness: Similarly, through reasonable sealing design, the aluminum alloy four-piece sliding window can fit tightly when closed, reducing air circulation and thus improving the air tightness of the window. This helps to maintain a stable indoor temperature, reduce energy consumption, and improve living comfort.
