One of the most significant advantages of aluminum window frame extrusions is their exceptional durability. Aluminum is inherently resistant to rust, corrosion, and various weather conditions, making it an ideal material for windows that must withstand the elements. Unlike wood, which can warp, rot, or be affected by termites, aluminum maintains its integrity over time. This strength ensures that the window frames will operate smoothly and remain visually appealing for years, reducing the need for frequent maintenance or replacement.
