Square Gazebo Style Roof Lantern - Made to Measure

Our Square Gazebo Style Roof Lanterns are made to measure with equal-sized sides to create a traditional, symmetrical lantern roof. Designed for installation onto a suitable flat-roof upstand or kerb, they create an attractive architectural feature while bringing additional natural daylight into the room below.

Each roof lantern is supplied as a complete system, including the uPVC window frames, gazebo-style lantern roof, guttering, your selected polycarbonate or glazed roof option and a decorative finial.

Made-to-Measure Square Roof Lantern

The lantern can be manufactured to suit your required square opening. The example shown is approximately 1050mm x 1050mm, but alternative dimensions can be manufactured to suit your project.

Because the width and length are equal, the finished lantern creates a balanced square gazebo-style roof that works particularly well over square roof openings.

Please note: Larger roof lanterns may require a different roof configuration to provide the necessary structural support while retaining the gazebo-style appearance.

Complete Gazebo Roof Lantern System

The roof lantern is supplied as a complete package with the main components required to create the finished structure.

• uPVC window frames
• Gazebo-style roof structure
• Roof guttering
• Polycarbonate or glazed roof option
• Decorative finial

Understanding the Roof Lantern Sizes

Important: The sizes entered when ordering refer to the internal frame dimensions. They are not the overall external dimensions of the complete roof lantern.

The uPVC window profiles are approximately 70mm wide. To calculate the approximate overall external frame dimensions, add 140mm to both the stated width and length.

The cill is approximately 160mm wide. To calculate the approximate overall external cill dimensions, add 320mm to both the stated width and length.

Example - 1000mm x 1000mm Square Roof Lantern

• Internal frame size: 1000mm x 1000mm
• Approx. external frame size: 1140mm x 1140mm
• Approx. external cill size: 1320mm x 1320mm

Example - 1050mm x 1050mm Square Roof Lantern

• Internal frame size: 1050mm x 1050mm
• Approx. external frame size: 1190mm x 1190mm
• Approx. external cill size: 1370mm x 1370mm

Please check all internal frame, external frame and cill dimensions carefully before ordering.

Glass or Polycarbonate Roof Lantern

Choose between glass or polycarbonate roof glazing to suit the requirements of your project.

The choice of roof material allows you to configure the lantern according to the appearance, natural light and thermal performance required for the installation.

Traditional Gazebo-Style Lantern Roof

The square design creates the distinctive appearance of a traditional gazebo roof lantern, with the roof rising towards the centre and finished with a decorative finial.

This makes it an attractive alternative to a simple flat rooflight where a more prominent architectural feature is required.

Ideal for Flat Roof Extensions

A square roof lantern can transform a flat-roofed room by introducing daylight from above and creating a greater feeling of height and space.

Suitable applications can include:

• Flat-roof extensions
• Kitchen extensions
• Dining areas
• Garden rooms
• Conservatories
• Orangeries
• Other suitable flat-roof projects

Frequently Asked Questions

Are the roof lantern sizes internal or external?

The sizes shown are the internal frame dimensions. You must allow for the width of the uPVC frames and cill when calculating the overall dimensions.

How do I calculate the external frame size?

Add approximately 140mm to both the width and length. For example, a 1000mm x 1000mm internal frame size gives an approximate external frame size of 1140mm x 1140mm.

How do I calculate the external cill size?

Add approximately 320mm to both the width and length. A 1000mm x 1000mm internal frame therefore has an approximate external cill dimension of 1320mm x 1320mm.

Can I order a 1050mm x 1050mm roof lantern?

Yes. A 1050mm x 1050mm internal frame size would have an approximate external frame size of 1190mm x 1190mm and an approximate external cill size of 1370mm x 1370mm.

Can I choose between glass and polycarbonate?

Yes. The roof lantern is available with a choice of glass or polycarbonate roof glazing.

Yes. The complete system includes the roof structure, uPVC frames, guttering and decorative finial, together with your selected roof glazing option.

Can larger square roof lanterns be manufactured?
