Conventional roof windows place overlapping sash frames directly over the mounting base, which casts noticeable perimeter shadows and reduces the effective glass area. By tucking the sash assembly entirely within the outer perimeter structural profile, this skylight eliminates bulky borders, allowing daylight to flow directly through a clean, unobstructed glass pane from edge to edge.
Roof openings face constant exposure to horizontal driving rain, accumulated water pooling, and severe thermal expansion. Traditional mechanically joined corners rely on sealant gaskets that can degrade, crack, and leak over time; full-perimeter seamless welding fuses the corner extrusions into an impervious single-piece shell, eliminating mechanical joints to guarantee leak-free performance.
The wireless sensor continuously scans for moisture contact on its sensitive exterior face. The moment rainfall or heavy precipitation begins, it transmits an instant encrypted radio signal to the internal Dooya motor, prompting an automatic override command that swiftly and fully seals the window without requiring any manual app or remote intervention.
Roof motors are frequently damaged by UV exposure, ambient condensation, and standing rainwater. Housing the high-torque Dooya motorized drive inside an integrated, sealed aluminum dry chamber protects the motor, drive tracks, and electronic circuits from weather corrosion, substantially extending the system's operational service life.
The versatile profile architecture accommodates a variety of structural demands. The fixed and vertical lift-up configurations are well-suited for pitched roofs and steep attic daylighting where upward clearance is ample, while the horizontal sliding track works on flat roofs or rooftop terrace access points where wind loads or overhead physical obstacles limit vertical travel.
