Our Roof Lanterns & Flat Roof Light Range
Brighten Your Home with Korniche Roof Lanterns and Flat Roof Lights
Bring natural light and a touch of architectural elegance into your home with our premium range of Korniche Roof Lanterns and Flat Roof Lights.
Designed with precision engineering and modern aesthetics, Korniche systems combine style, strength, and outstanding thermal performance, transforming any flat roof space into a stunning feature.
Whether you’re building a new extension, upgrading an existing space, or simply looking to add more daylight to your home, Korniche’s award-winning glazing solutions provide the perfect blend of form and function.
Most roof lanterns don't need planning permission because they fall under permitted development, provided the lantern doesn't rise more than 150mm above the plane of the existing roof or above the highest part of the roof.
Flats, maisonettes, listed buildings and homes in areas with restricted permitted development rights are treated differently, so it is worth checking with your local authority first.
Building Regulations still apply to the structure and its thermal performance, and we make sure every lantern we fit meets them.
A roof lantern is a raised, pitched glass structure that sits above a flat roof and draws light in from several angles, while a flat rooflight sits almost level with the roof for a minimal, flush finish.
A lantern adds height and a focal point to the room below, which suits larger kitchens and living spaces, whereas a flat rooflight suits single-storey extensions, kitchens and home offices where you want to keep the roofline low.
We supply and fit both from the Korniche range, which uses thermally broken aluminium throughout.
The Korniche roof lantern is designed for energy efficiency, with a thermally broken aluminium frame and slim sightlines that let in plenty of daylight without the heat loss of older lantern designs.
Choosing the right glass matters as much as the frame, especially on a south-facing roof where solar control glass can stop the room overheating in summer. We talk through the glazing options for your lantern at survey, so it performs well in winter and summer alike.
