Introduction
Due to the popularity of our roof terrace access rooflights, the designers at Glazing Vision have developed a design principle which can be used to offer a standard solution in both a free standing box rooflight or a 3 wall mounted version. Using these design principles cost and lead time reductions can be passed onto the customer.

The Sliding box rooflights are a great 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 you to continue your handrail 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 50% clear opening thus allowing the user to walk through and out of the rooflight. All the glass used is flush to allow water run off and easy cleaning, whilst maintaining maximum security.

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 a day.

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 then released leaving the rooflight to open automatically. If you wish the unit to stop, press close once. If you wish to have the unit only open a certain amount, you can keep the switch pressed until this point is reached.
