Sunlight into the middle of the room.
A roof lantern drops daylight straight into the heart of a space , anywhere you have a flat roof, you can have one. On a kitchen extension, it turns a dim back of house into the brightest room in the building. On a loft conversion, it brings sky views into a room that would otherwise feel enclosed.
Korniche is the reference‑standard aluminium lantern in the UK. Its structural rafters are self‑supporting up to 6m × 3m with no ridge beam, which means fewer fixings, cleaner sightlines, and faster installation than any competitor.
Slimmest sightlines in the category.
Korniche rafters are just 38mm wide , the thinnest in any lantern system on the market. From underneath, the glass dominates and the metalwork almost disappears. Combined with self‑cleaning, solar‑control low‑iron glazing as standard, the result is maximum light with minimum heat gain.
Available in 2‑bar, 3‑bar, 4‑bar and custom configurations. Powder‑coated in any RAL colour; matt black anthracite and traffic white are the most specified.
