What is a fanlight window used for?

A fanlight is the small top opening in a window unit. Hinged to a transom – the horizontal beam that divides the glazing panes – fanlight windows enable safe ventilation of interior spaces.

Fanlights are suitable for use in uPVC, timber, timber alternative, and aluminium window systems.

Why is it called a fanlight?

Also known as a ‘sunburst light’, traditional fanlights were semi-circular and used above doorways. They take their name from the way their fixed glazed panes ‘fan out’ like a folding handheld fan. The term now covers all small top opening windows, regardless of shape.

What are the advantages of installing a fan light window?

  • Fanlights guide natural light deeper inside via the ceiling reflections, no matter how big or small the space is
  • Fanlights above doors illuminate dark hallways & corridors
  • They allow light & air in without compromising on security
  • Their limited opening feature keeps children & vulnerable adults safer
  • Rooms remain at a comfortable temperature without getting draughty

Are bespoke fanlight windows possible?

There is a range of ironmongery options for fanlight openings, depending on the design of the window, the window opening mechanism, and your interior preferences.

Leaded fanlights are an effective way to add style and colour to your windows to suit the style and age of your home. Leaded fanlights are available in a range of designs and colours, easily matched to existing windows and doors. Decorative fanlight glass is also a popular option, with a wide range of stained, etched and frosted glass to choose from to make your fanlight as unique as you are.
