Product Description
The Upvc Top Hung Window manufactured by our facility utilizes a top-hinged, outward-projecting sash configuration, with opening angles held between 15° and 45° via multi-link stainless steel friction stays. The outward-tilted sash serves as a protective weather canopy, enabling continuous passive cross-ventilation while deflecting wind-driven rain away from the opening. Engineered for bathrooms, kitchens, basement storage rooms, stairwells, hospital wards, and high-level clerestory ribbons, this Upvc Top Hung Window pairs the thermal insulation of UPVC multi-chamber profiles with continuous compression gaskets, delivering energy savings, reliable air exchange, and safe operation that prevents accidental falls.
Application Scenarios
- Moisture-prone spaces requiring continuous, rain-safe passive ventilation, such as bathrooms, commercial kitchens, and utility basements.
- Corridors, hospital wards, and school classrooms requiring mechanical limits on sash opening spans to prevent fall hazards.
- Factory clerestory bands, warehouse high-wall vents, and public corridors needing natural daylighting and weather-safe airflow.

Customization Capabilities
As an OEM/ODM source manufacturer, we adapt profile wall thicknesses, privacy glazing types, and perimeter sealing systems to contractor elevation drawings. For high-wall placements beyond manual reach, we can factory-fit 24V or 220V electric chain actuators. Within our 5,000,000 RMB project MOQ, frame dimensions and profile surface treatments can be mixed. Functional engineering samples are completed within 7 days, with free samples provided for site evaluation.
Quality Assurance & Factory Strength
Our workshop utilizes CNC profile cutting equipment, high-strength corner welding machines, and dedicated copy routers to ensure accurate positioning of hardware tracks and strike plates. The quality department conducts end-to-end inspections across all production stages. Prior to packaging, a 100% full inspection is carried out on every unit, examining stay friction torque, handle latching tension, and gasket compression. With a monthly capacity of 5,000 square meters, our facility welcomes third-party inspections and backs all products with a 1-year warranty.
Commercial FAQ
Q: Can these high-mounted top-hung windows be automated for remote operation?
A: Yes. We can pre-machine mounting brackets and internal wiring paths at the factory, integrating electric chain actuators compatible with wall switches, remote controls, or central fire-smoke evacuation systems.
Q: How long does production take for custom top-hung window orders?
A: Manufacturing is completed within 30 days for standard units and 35 days for custom configurations from raw material intake, adhering strictly to contractual schedules.
Q: What trade terms and settlement currencies are accepted?
A: We support standard FOB and EXW commercial terms. Standard orders require a 50%–60% advance deposit; custom orders require a 70% deposit, with the remaining balance settled in RMB prior to shipment. Goods are crated in solid wooden boxes.
