2750mm x 2750mm Made to Measure Glass Flat Roof Window Lantern

Our 2750mm x 2750mm Square Gazebo Style Roof Lantern is a large made-to-measure flat roof window lantern designed with four equal sides to create an impressive, symmetrical gazebo-style roof. This substantial lantern introduces natural daylight from above while creating an attractive architectural centrepiece within the room.

Ideal for large flat roof extensions, kitchens, kitchen-diners, 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.

2750mm x 2750mm Square Roof Lantern

The stated 2750mm x 2750mm measurement is the internal frame size. With four equal-sized sides, the lantern creates the balanced square shape associated with a traditional gazebo-style roof.

At 2750mm square internally, this is a particularly large roof lantern suitable for projects where a substantial overhead glazed feature is required.

Complete Made-to-Measure Roof Lantern

The 2750mm square gazebo roof lantern is supplied as a complete roof system with the main components required to create the finished structure.

• Internal frame size: 2750mm x 2750mm
• Design: Square gazebo style with four equal sides
• Manufacture: Made to measure
• uPVC window frames: Included
• Lantern roof structure: Included
• Roof guttering: Included

2750mm x 2750mm Internal Frame Size

Important: The stated 2750mm x 2750mm 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 2890mm x 2890mm.

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 3070mm x 3070mm.

2750mm x 2750mm Roof Lantern Dimensions

• Internal frame size: 2750mm x 2750mm
• Approx. external frame size: 2890mm x 2890mm
• Approx. external cill size: 3070mm x 3070mm

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

Large Square Gazebo Style Roof Lantern

The four equal sides give this lantern its distinctive square gazebo-style appearance. The combination of vertical uPVC window frames and the raised roof structure creates additional height and makes the lantern a prominent feature within the room below.

With an internal frame measuring 2.75m x 2.75m, this lantern is particularly suited to larger rooms and open-plan spaces where a generous area of overhead glazing 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 2750mm x 2750mm 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 Option

Choose glass roof glazing for the clean appearance associated with a traditional glazed roof lantern. The raised glazed roof allows daylight to enter from above and can help brighten areas towards the centre of a large room.

Polycarbonate Roof Lantern Option

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

Ideal for Large Flat Roof Extensions

A 2750mm x 2750mm flat roof lantern can make a significant difference to a large extension by introducing natural light into areas that may otherwise be some distance from external windows and doors.

Suitable applications can include:

• Large flat roof extensions
• Kitchen extensions
• Kitchen-diners
• Open-plan living spaces
• Family rooms
• Garden rooms
• Conservatories
• Orangeries
• Other suitable flat roof projects

Made-to-Measure Flat Roof Window Lantern

Check Your Roof Lantern Measurements

Because the ordering dimensions refer to the internal frame size, additional space must be allowed for the window frames and cill when preparing the supporting structure.

For this 2750mm x 2750mm lantern, the approximate dimensions are:

• Internal frame: 2750mm x 2750mm
• External frame: 2890mm x 2890mm
• External cill: 3070mm x 3070mm

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