Aluminum Alloy Manual Skylight (High Sealing Performance)

The aluminum alloy manual skylight delivers reliable daylighting and ventilation through a simple, direct-operation mechanism, available as either a hand-crank system or a telescopic push-rod. It requires no electrical supply and remains fully functional during power outages, ensuring dependable operation in all conditions.

A continuous EPDM sealing system runs along the full perimeter of the sash, providing excellent airtightness, watertight performance, and acoustic insulation comparable to motorized skylight systems. This high-sealing design effectively prevents air leakage and water ingress, maintaining interior comfort even under challenging weather conditions.

The aluminum alloy frame is engineered for rooftop structural demands and treated with anti-corrosion finishes for long-term durability. Installation is designed to be non-invasive, preserving the integrity of the existing roof waterproofing system.

This high-sealing configuration is ideal for residential rooftops, sunrooms, and loft spaces where thermal performance, weather protection, and airtight construction are key priorities.
