Product Description
Engineered for reliable, all-weather ventilation, our Aluminium Windows Top Hung features a top-hinged sash that swings outward from the bottom, with opening angles precisely held between 15° and 45° via heavy-duty stainless steel friction stays. This outward-tilting geometry forms an effective weather canopy, deflecting rainfall away from the opening while maintaining natural air circulation without water ingress. We manufacture this Aluminium Windows Top Hung for high-level clerestory ribbons in public facilities, commercial walkways, school corridors, hospital wards, basement lightwells, and modern kitchens, offering a practical window solution that balances controlled passive airflow with reliable fall-prevention safety.
Application Scenarios
- Bathrooms, basement equipment spaces, commercial kitchens, and stairwells requiring continuous, rain-safe passive ventilation.
- School classrooms, hospital corridors, and commercial office circulation areas requiring physical restrictors on sash opening spans.
- Industrial production facilities, warehouse facade light strips, and curtain wall transoms requiring high-level natural venting and smoke extraction.

Customization Capabilities
We provide comprehensive CAD design detailing and OEM/ODM fabrication for high-level facade bands and punch openings. The system supports manual cam handles, extended manual crank operators, or pre-wired 24V/220V electric chain actuators integrated into building automated fire-smoke evacuation systems. Within our 5,000,000 RMB project MOQ, frame colors and profile dimensions can be customized. Functional sample units are completed within 7 days, with free samples available for site mockups.
Quality Assurance & Factory Strength
Our 20-person in-house production crew enforces end-to-end quality tracking across profile sawing, punching, assembly, and sealing. The plant uses high-precision CNC cutting saws and dedicated punching dies to align friction stay mounting holes and strike positions. Before packaging, every window undergoes a 100% full inspection auditing friction stay load-bearing friction, handle engagement, and corner joint sealant integrity. We welcome third-party factory inspections and support all units with a 1-year factory warranty.
