Sliding rooflight with one section sliding on rails over a roof, creating a 100% clear opening. All the glass is flush to allow water runoff and easy cleaning. Thermally broken frame detail and insulated flashings on the sliding frame almost eliminates direct contact between the warm internal frame and the exterior cold air, reducing heat loss and condensation. Carriage design includes large diameter wheels to give minimal rolling resistance on the anodized rails.

All Glazing Vision sliding rooflights are low-noise in operation and have built in electronic solid-state controls with battery back-up, manual override, speed control and creep-speed sealing at end of travel as standard. Units are factory pre-assembled and tested, usually craned into position, fitted and commissioned within day. Manual override of the unit is via a 90° turn of an Allen key to engage/ disengage the motor from the drive mechanism and allow the product to be pushed open/ closed.

The rooflight is opened electrically, operated by a rocker switch positioned at the discretion of the client. It includes a ‘one touch’ facility, where the switch is pressed and then released leaving the rooflight to open automatically. The unit can be stopped by pressing close once or can be only part opened by keeping the switch pressed until the desired point is reached. Includes drainage on rails to reduce build up of surface water on framework.
