Home > Companies > Glazing Vision Ltd > GV Standard Box Rooflight

Sliding rooflight with one single sliding door retracting over fixed glazing available in either a free-standing box rooflight or a three wall mounted version. It is a good option for terraced access as it offers a physical structure and the fixed walls of glass provide a balustrade around the opening. It also allows the handrail to continue right up to the point of leaving the box and stepping onto the roof terrace. The box rooflight consists of two sections, one fixed section and one sliding section. The sliding section slides over the fixed section to create a 50% clear opening thus allowing the user to walk through and out of the rooflight. All the glass used is flush to allow water runoff and easy cleaning, whilst maintaining maximum security.

The thermally broken detail on the fixed frame 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 forming. Carriage design includes large diameter wheels to give minimal rolling resistance on the anodized rails. Includes drainage on the lower track to reduce build up of debris within the framework.

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.
