Why Choose a Round Rooflight?

A round flat rooflight is an excellent way to introduce natural daylight while adding a distinctive design feature to your home. The circular shape creates a modern architectural look and can work particularly well in kitchens, extensions, hallways, bathrooms, living spaces and other areas where additional daylight is required.

Our triple glazed round rooflights are designed to provide excellent thermal and acoustic insulation. The triple-glazed construction helps reduce heat loss, improve comfort and reduce external noise, while also helping to minimise condensation.

The large glazed area allows natural daylight to enter the room from above, helping to make darker areas feel brighter and more spacious. The self-cleaning outer glass also helps reduce ongoing maintenance.

Round Rooflight Sizes

We offer a selection of round rooflight sizes to suit different flat roof projects. Our standard range includes a variety of diameters, making it easier to choose a rooflight to suit your available roof space and desired level of natural daylight.

Each product listing clearly shows the external diameter, internal diameter and structural opening required, allowing you to select the correct size for your project.

High-Performance Triple Glazing

Our round rooflights feature high-performance triple glazing incorporating Low-E glass and Argon gas to provide excellent thermal insulation. The outer pane is made from 6mm toughened self-cleaning glass, providing durability while helping to reduce cleaning and maintenance requirements.

With a U-value of 0.83 W/m²K, our standard triple glazed rooflights provide excellent thermal performance. Triple glazing also provides improved acoustic insulation, helping to reduce external noise and create a more comfortable indoor environment.

Installation & Structural Opening

Our round rooflights are suitable for both new and existing flat roof applications. When choosing your rooflight, it is important to check the structural opening requirement and ensure that the roof construction is suitable for the chosen rooflight size.

For detailed fitting information and technical guidance, please see our Installation / Fitting Guide.

Custom Round Rooflights

If you require a round rooflight size or specification that is not listed in our standard range, Modern Rooflights can also supply custom rooflight solutions.

We can discuss enhanced specifications where required for individual buildings and projects. If you are unsure which rooflight specification is most suitable, please contact us before ordering and we will be happy to help.

Choosing the Correct Rooflight Specification

Every building and project is different, so it is important that customers check that the rooflight specification is suitable for their building and project requirements before placing an order.

Our standard round rooflights provide excellent thermal, acoustic and daylight performance, but where a project requires an enhanced specification, we can upgrade the rooflight specification to suit your individual requirements. Our team can discuss the available options and help you identify the most appropriate solution for your project.
