• SYSTEM MECHANICS

How Does a Top-Hung Skylight Work?

Understand the core pivot mechanics, drive hardware, and operational pathways that allow top-hung skylights to provide smooth, unobstructed rooftop ventilation.

PART 01

Top-Hinged Opening

The window sash connects directly to the outer structural frame along the top edge via specialized hinge pivot points. When activated, the sash swings outward and upward, elevating the panel without intruding into interior headroom. The specific opening angle is calibrated to match the structural depth and frame design.

PART 02

Manual or Electric Operation

Manual skylights employ direct mechanical winding handles or crank rods to smoothly push the sash outward. Electric variants feature motorized mechanical actuators that drive the sash open and closed seamlessly via wall control, wireless remote, or automated weather sensors.

PART 03

Different Actuator Configurations

Drive hardware is configured to match architectural aesthetics and panel dimensions: surface-mounted external actuators offer high mechanical force and straightforward maintenance; concealed actuators mount inside aluminum profile chambers for a flush, clean frame interior; and double-screw drive structures use twin synchronized spindles to evenly distribute lifting force across wide glass spans.
