Anti Rain Ingress Design Aluminum Alloy Suspended Skylight

The Anti Rain Ingress Design Aluminum Alloy Suspended Skylight opens by rotating the sash upward from the bottom edge, forming a triangular ventilation gap at the base of the frame. This geometry allows fresh air to enter while the angled sash panel acts as a natural shield, deflecting rainwater away from the opening and significantly reducing the risk of rainwater backflow during operation.

This design provides superior rain protection compared to conventional sliding or lift-up skylights, making it especially suitable for regions with frequent rainfall. Even when partially open, the skylight maintains effective resistance against water ingress.

When closed, a multi-layer sealing system ensures reliable waterproofing and wind resistance. The aluminum frame is engineered for rooftop conditions and treated for long-term durability under outdoor exposure.

The system is available in manual operation as standard, with optional motorization. This anti-backflow configuration is ideal for villas, sunrooms, and residential rooftops where maintaining ventilation during light rain without water intrusion is essential.
