Circular Rooflight
Design – Supply – Installation
Bespoke circular rooflights designed to maximise natural daylight
A circular rooflight is a fixed overhead glazing solution featuring a round glass format, typically installed on flat or low-pitched roofs. The circular shape allows light to spread evenly throughout the space below, reducing harsh shadows and creating a soft, natural daylight effect.
Circular rooflights are commonly used in kitchens, living spaces, stairwells, commercial buildings, and architectural feature areas where both light and design impact are important.

Proven in Real Projects
Our circular rooflights have been specified and installed across a wide range of real-world projects, including education, healthcare, and commercial environments.
They have been used successfully on projects such as Maggie’s Centre and Fennies Nursery across London and Sutton, where daylight performance, safety and comfort were key considerations.
Each project is assessed individually to ensure the rooflight specification meets structural, thermal and environmental requirements.
Circular Rooflight Variations
Standard Circular Rooflights
These non-opening roof windows are ideal for spaces where ventilation is not the prime purpose of installation, offering an unobtrusive solution for enlightening interior spaces.
Large Format Circular Rooflights
For projects requiring larger spans or increased daylight coverage, we design and manufacture large circular rooflights with upgraded glass specifications to meet wind and snow load requirements.
Structural Circular Rooflights
Where minimal framing or structural glazing is required, circular rooflights can be engineered as part of a structural glazing solution, incorporating laminated safety glass designed to support increased loads, including walk-on glass applications where specified.
Benefits Of an Circular Rooflights
Circular rooflights introduce daylight evenly from above, creating a bright and welcoming internal environment. Their symmetrical form enhances architectural balance while avoiding harsh light patterns.
They are particularly effective in:
-
Open-plan living spaces
-
Central roof areas
-
Commercial and education buildings
-
Feature ceilings and stairwells
Circular rooflights can also be combined with advanced glass options to control heat, noise, and privacy depending on the application.

Solar Control Circular Rooflights
Solar control glass reduces heat gain and UV exposure, helping maintain comfortable internal temperatures, especially in south-facing installations.
Acoustic Circular Rooflights
Acoustic laminated glass can be specified for projects near roads, railways, or other noise-sensitive environments.
Switchable Circular Rooflights
Switchable glazing allows instant privacy at the touch of a button, changing from clear to opaque when required.
Heated Circular Rooflights
Heated glass options are ideal for swimming pools, spa areas, or high-humidity environments where condensation control is essential.
