Product Overview
Aluminium hopper windows are top-hinged windows with a bottom-outward opening action. The sash tilts inward at an angle typically between 15° and 45°, so the window provides ventilation without projecting outward from the building facade.
These windows are used in hotel bathrooms, high-rise corridor ventilation openings, commercial building passage windows, residential kitchen and bathroom ventilation, and high-window replacement in renovation projects.
Core Advantages
Ventilation with minimal indoor footprint:
The sash tilts inward rather than swinging into the room. In hotel bathrooms and corridors, this allows continuous air movement while keeping the window from interfering with interior circulation.
Rain-resistant ventilation position:
In the tilted position, the opening remains protected from direct rain entry. This suits hotel bathrooms and corridors where ventilation is needed even during wet weather.
Top-hinged hardware configuration:
The window uses top hinges with a handle, friction stay, transmission box, locking points, and locking seats. The opening angle is controlled between 15° and 45°, which matches the ventilation requirements of bathroom and corridor applications.
Material build for mid-to-high-end projects:
The frame is made from 6063-T5 aluminium profiles with PA66 thermal break bars and multiple EPDM sealing strips. This combination supports air tightness and thermal performance requirements in hotel and commercial projects.
Applications
• Hotel bathroom ventilation windows
• High-rise building corridor daylight and ventilation windows

Quality Control
- Incoming aluminium profiles are checked against the confirmed material grade, wall thickness, and surface color number. Any scratches, corner damage, or warping are identified before the profiles enter processing.
- During cutting and drilling, frame dimensions, hole spacing, and hole positions are checked against the approved drawing. After assembly, the opening angle, hardware function, and sealing strip fit are inspected on a first-piece basis before batch processing continues.
- Before packing, each window undergoes a 100% inspection. Third-party inspection is supported. Standard products carry a 10-year warranty; hardware accessories carry a 2-year warranty.
