Segmented Dome Rooflights

Our Segmented Dome rooflights feature curved double skin polycarbonate glazing contained within polyester powder coated aluminium frameworks.

These rooflights are suitable for all types of flat or low pitched roofs. They provide great visual impact and are often used as centrepieces or points of focus for large internal spaces like halls or atria.

Our Segmented Dome rooflights are made to order in sizes to suit specific requirements, for installation to structural kerbs by others.
