When installing an aluminum alloy window, it's important to ensure that the window closes properly with even gaps around the frame. The deviation between the sash and the frame, or the parallelism of adjacent sides, should not exceed 2 mm. The window should open smoothly and function easily without any resistance.
To check the sliding mechanism, make sure the track is installed flat and free of obstructions. Gently push the window to test if it slides smoothly without any sticking or jerking. Any unevenness in the track can affect the performance and lifespan of the window.
The frame and cross frame of the balcony’s aluminum window must be securely fastened to the balcony railing and the top structure. Typically, this is done using nails or rivets embedded in concrete. For added stability, painted angle steel is often used during installation. It's crucial not to fix the window directly to brick walls, nor to use wooden wedges in place of a nail gun. The gap between the upper track and the top rail should be filled with cement mortar to prevent water leakage into the room during rainy weather.
Additionally, the wall thickness of the aluminum profile should not be less than 1.2 mm, and the joint thickness between the window frame and the wall should not be less than 1.5 mm. These specifications help ensure the durability and structural integrity of the window over time.
