Technical Features Of Aluminum Alloy Casement Windows

In terms of technical specifications, the core advantage of aluminum alloy casement windows lies in the soundness of their structural design. The window sash is connected via butt hinges or friction hinges, offering high load-bearing capacity that supports larger glass panes. Regarding profile design, the wall thickness of primary load-bearing sections often exceeds 1.8 mm, ensuring the window remains undeformed during long-term use. In terms of sound and thermal insulation, the use of triple-pane insulating glass and a thermal break structure allows the window assembly to achieve a heat transfer coefficient as low as 1.0 W/(m²·K) and sound insulation exceeding 40 dB. Additionally, the drainage system is typically designed to be concealed, preventing rainwater backflow.
