The Opal rooflight

Providing a clear view of the outside world

The Opal Rooflight is a contemporary fixed rooflight system that provides maximum daylight with minimal framework. Perfect for letting natural light into the room, the Opal Rooflight can enhance any living space.


With slimline design and high performance glass, you can let the light flood into the room with an Ultrasky Lantern. This lantern is highly flexible and can respond to many design requirements.

The Ultrasky Lantern can be inserted into a flat roof or a traditional orangery deck and is ideal for large builds where the roof height is restricted. Unlike many other lanterns, Ultrasky Lantern has a 25° pitch which draws more light into the room creating a stunning focal point.

Ultrasky Lantern’s extra strength means less bars and uninterrupted sight lines for maximum light. It is available in a wide variety of sizes to a maximum width of 4m and a length of 5.8m.
