Bagaimana Jendela Aluminium Menangani Pergerakan atau Fleksi Bangunan?

Buildings expand, contract, and sway under thermal shifts, wind loads, or seismic activity. Aluminum window systems adapt through engineered anchor and gasket design. Anchors between window frames and sub-frames use slotted holes and rotating brackets, allowing 10–15 mm of lateral movement without transferring stress to glazing or seals. Continuous compression gaskets cushion the frame-panel interface, accommodating differential movement between aluminum panels, window frames, and concrete or steel structure. Pressure-plate systems secure panels and windows but feature masked fasteners beneath removable covers, enabling the frame to slide slightly within the pressure plate groove under movement. For suspended aluminum ceilings above windows—commonly in soffits—the ceiling carrier channels use clip-in panels with spring-loaded retainers, permitting 5 mm vertical deflection while maintaining alignment with the window head. Thermal isolation blocks in the mullion-transom grid also break conductive paths, reducing movement forces. Together, these details create a resilient envelope where windows, facades, and ceilings move harmoniously, preventing seal failure and preserving the integrity of the building skin.
