Large Square Gazebo Style Roof Lantern

The four equal-sized sides give this lantern its distinctive square gazebo-style appearance. At 2.5 metres square internally, this is a substantial roof lantern capable of creating a dramatic centrepiece within a large extension or open-plan living space.

Please note: The roof lantern shown in the product photographs may be the smaller 1m x 1m version. Larger roof lanterns require different roof configurations to provide the necessary structural strength and support.

The roof configuration of the 2500mm x 2500mm lantern may therefore differ from the smaller lantern illustrated.

Glass or Polycarbonate Roof Options

The roof can be supplied with a choice of glass glazing or polycarbonate roofing, allowing the lantern to be specified to suit the requirements and budget of your project.

Glass provides a clean glazed appearance with excellent natural daylight, while polycarbonate provides a lightweight and practical alternative.

Ideal for Large Flat Roof Extensions

The 2500mm x 2500mm roof lantern is particularly suited to larger flat roof extensions where daylight needs to reach further into the centre of the room.

Typical applications include large kitchens, kitchen-diners, open-plan living areas, conservatories, garden rooms and other flat roof buildings where a substantial overhead rooflight is required.

Made to Measure Glass Flat Roof Window Light

Our square gazebo roof lanterns provide a traditional lantern appearance combined with the convenience of a complete made-to-measure system. The windows, roof structure, guttering, glass or polycarbonate roofing and decorative finial are supplied together.

Important: Please carefully check the internal frame, external frame and external cill dimensions before constructing the roof opening, kerb or supporting structure.
