Installed on a new build extension, Orangery, or inserted into an existing flat roof, an Ultrasky lantern will help you add the feeling of space and natural light to your home.


Whether it’s for a living room, dining room, kitchen, bedroom or bathroom the Ultrasky Lantern will be the perfect stylish solution for you.

The Ultrasky lantern is stunning, enhancing any style of property, traditional or modern alike. It reduces the need for a chunky roof ridge and maximises the amount of glass that allows light to flood into your room. 

The Ultrasky lantern roof is available in a number of bespoke rectangular sizes ranging from 1000mm x 1500mm to 4000mm x 5850mm.

Choose the stylish White PVCu option to match your modern window frames, or for that extra “Wow” factor go for the Aluminium option, available in White, Anthracite Grey or Satin Black. Internally the lantern roof is clad in white PVCu or upgraded to anthracite grey or satin black to either match or contrast the external finish.


The highly thermally efficient glazing options will help reduce heat loss and noise pollution, whilst letting the desired amount of light into your room.


Add a roof vent to let in the fresh air – roof vents are available with a manual opener, automatic opener or an automatic opener with rain and temperature control. * (roof vents only available in selected sizes).
