The Glazing Vision VisionVent Rooflight is designed to provide a combination of natural daylight and natural ventilation to your space, it has been specifically designed by our specialist in-house team for ventilation purposes, offering smooth and reliable operation in three ways; Manual, Electric or Chain-Actuated.
The manually operated VisionVent opens using a screw jack mechanism which is mounted inside the internal aperture and opened using a telescopic crank handle.
The chain actuated VisionVent is powered open by an integrated chain drive unit which is seamlessly housed within the rooflight frame.
The electrically operated VisionVent is driven by twin drive synchronised mechanisms, which allows larger sizes to be manufactured and full connectivity to extra options such as remote control and building management systems.
Each VisionVent unit features dual colour, thermally broken framework and is supplied with heat soak tested low e toughened glass as standard.
