Alloy Grade: 6063‑T5 (standard for architectural window & door profiles)
Surface Treatment: Anodizing, powder coating, electrophoresis, wood grain transfer
Performance: Windproof, waterproof, sound insulation, heat insulation, anti‑aging
Structure: Stable frame design, high tightness, strong deformation resistance
Tolerance: High dimensional accuracy for smooth assembly and installation
The thermal break casement window is mainly composed of the following aluminum profiles:

These extruded aluminum profiles provide a reliable and versatile solution. With their ability to withstand harsh weather conditions and maintain structural integrity over time, they are a preferred choice for architects, builders, and homeowners alike.
The thermal break casement window is mainly composed of the 5 systerms:
Profiles systerm:The profile system refers to the main frame materials and structure of the broken bridge aluminum window, including the design and manufacturing process of profiles such as window frames and window sashes.
Thermal break systerm:The Thermal insulation system mainly refers to the function of the Thermal Break Strip. By breaking the aluminum alloy profiles through the thermal break strip, the heat conduction is effectively blocked.
Sealing systerm:The sealing system includes sealing rubber strips, sealing wool strips, silicone sealant, etc., which are used to prevent the penetration of air and water and improve air tightness and water tightness.
Glazing systerm:The glass system refers to the types and structures of glass used in Windows, such as insulating glass, double-glazed glass, low-emissivity glass, etc., mainly for heat insulation, sound insulation and lighting.
Hardware systerm:The hardware system includes hardware accessories such as locks, hinges, slides, and handles, which are used to achieve the functions of opening and closing, fixing, and operating Windows.
