2250mm x 2250mm Made to Measure Glass Flat Roof Window Lantern

Our 2250mm x 2250mm Square Gazebo Style Roof Lantern is a large made-to-measure flat roof window lantern featuring four equal-sized sides for a balanced and symmetrical gazebo-style appearance. Designed for larger flat roof areas, it creates an impressive architectural feature while bringing additional natural daylight into the room below.

Ideal for large extensions, kitchens, dining rooms, open-plan living areas, conservatories and garden rooms, the lantern is supplied as a complete system with the uPVC window frames, roof structure, guttering, your selected glass or polycarbonate roofing and a decorative finial.

2250mm x 2250mm Square Roof Lantern

The stated 2250mm x 2250mm measurement is the internal frame size. With four equal sides, the lantern creates the distinctive symmetrical appearance associated with a traditional square gazebo-style roof.

At 2250mm square internally, this is a substantial roof lantern particularly suited to larger rooms where overhead glazing can help introduce daylight towards the centre of the living space.

Complete Made-to-Measure Roof Lantern

The 2250mm square roof lantern is supplied as a complete roof system with the main components required to create the finished structure.

• Internal frame size: 2250mm x 2250mm
• Design: Square gazebo style with four equal sides
• Manufacture: Made to measure
• uPVC window frames: Included
• Lantern roof structure: Included
• Roof guttering: Included

2250mm x 2250mm Internal Frame Size

Important: The stated 2250mm x 2250mm size is the internal frame measurement. It is not the overall external dimension of the complete roof lantern.

The uPVC window profiles are approximately 70mm wide. This adds approximately 70mm to each side, or 140mm to the overall width and length.

The approximate external frame size is therefore 2390mm x 2390mm.

The cill extends approximately 160mm on each side, adding approximately 320mm to the stated internal width and length.

The approximate overall external cill size is therefore 2570mm x 2570mm.

2250mm x 2250mm Roof Lantern Dimensions

• Internal frame: 2250mm x 2250mm
• Approx. external frame: 2390mm x 2390mm
• Approx. external cill: 2570mm x 2570mm

Please check all dimensions carefully before constructing the roof opening, supporting kerb or upstand.

Large Square Gazebo Style Roof Lantern

The four equal sides create the distinctive square gazebo roof lantern design. The combination of vertical uPVC window frames and the raised roof above creates additional height and makes the lantern an attractive focal point within the room.

The generous 2250mm x 2250mm internal dimensions make this lantern particularly suitable for larger extensions and open-plan rooms where a substantial overhead glazed feature is required.

Important Roof Configuration Information

Product photographs may show the smaller approximately 1m x 1m version of the gazebo roof lantern. Larger roof lanterns require different roof configurations to provide the necessary strength and structural support.

The exact roof configuration of the 2250mm x 2250mm lantern may therefore differ from the smaller lantern illustrated. The roof structure will be configured appropriately for the larger dimensions while retaining the overall gazebo-style appearance.

Glass Roof Lantern

Choose glass roof glazing for the appearance associated with a traditional glazed roof lantern. The raised glazed roof provides an attractive way of introducing natural daylight from above while creating a distinctive feature within the room.

Polycarbonate Roof Lantern

A polycarbonate roof is also available as an alternative to glass. Polycarbonate provides a lightweight and practical roofing option while retaining the raised square gazebo-style lantern design.

Ideal for Large Flat Roof Extensions

A 2250mm x 2250mm flat roof lantern can be particularly effective in larger extensions where conventional windows and doors may not provide sufficient daylight to the centre of the room.

Suitable applications can include:

• Large flat roof extensions
• Kitchen extensions
• Open-plan kitchens and dining rooms
• Family living areas
• Garden rooms
• Conservatories
• Orangeries
• Other suitable flat roof projects

Check Your Roof Lantern Measurements

Because the ordering dimensions refer to the internal frame size, the external dimensions must be allowed for when preparing the supporting structure.

For this 2250mm x 2250mm lantern, allow approximately 2390mm x 2390mm for the external frame and approximately 2570mm x 2570mm for the external cill.

Always check the final required dimensions before constructing the roof opening, kerb or supporting upstand.
