The thin‑profile low‑height ventilation skylight is a compact roof ventilation unit targeting height‑limited building conditions and old‑factory renovation scenarios. With reduced overall elevation, it solves the problem that traditional high‑type skylight cannot be installed under roof‑height restriction. It realizes natural ventilation, daylighting and fire smoke‑exhaust, with favorable wind‑resistance performance, widely used for reconstruction and new‑build industrial roof projects.
This low‑height skylight abandons large‑height arched shell structure, adopts thin‑integrated layout. It can be installed on roof ridge or roof slope position. For old‑factory reconstruction, it does not need large‑scale modification of original roof structure. Under normal working condition, sash opens for hot‑air exhaust; when fire alarm signal comes, sash opens rapidly for smoke‑vent; when raining, sash closes to guarantee roof waterproof performance. Modular splicing can match different ventilation‑volume requirements.
Hot‑dip galvanized steel profile, compact height design, reduce whole‑unit wind‑load area, good stability under strong‑wind environment.
Two optional schemes: translucent anti‑UV FRP / polycarbonate panel for daylighting; or galvanized steel plate for non‑daylighting ventilation‑only requirement.
Compact‑stroke electric push‑rod matches low‑height sash structure; with manual emergency opening mechanism for power‑off emergency condition.
Integral water‑collecting trough structure, collect rainwater and condensate water, avoid water penetration at roof‑connection position, specially optimized for old‑roof reconstruction waterproof risk.
Continuous aging‑resistant EPDM sealing strips around sash gap, lower rain‑splash and dust‑infiltration risk under closed state.
