Korniche Roof Lanterns
Flood Your Home With Natural Light
A Korniche roof lantern is designed to transform flat roof extensions by maximising daylight, improving thermal performance, and adding a clean, architectural finish to your space.
Unlike traditional lanterns adapted from conservatory systems, Korniche roof lanterns are engineered from scratch specifically for modern homes — delivering slimmer sightlines, stronger structure, and faster installation.
Whether you’re extending a kitchen, renovating a living space, or upgrading an existing flat roof, a Korniche lantern brings light, height, and a real sense of openness.

Why Choose a Korniche Roof Lantern?
Korniche has become one of the most respected names in roof lantern design by doing things differently — starting with a clean sheet of paper, not a compromise.
Designed from the ground up
Korniche roof lanterns are not modified conservatory roofs. Every component is purpose-designed to work together, resulting in a stronger, slimmer and more refined system.
Ultra-slim ridge and rafters
Narrow aluminium sections mean more glass and less frame, allowing natural light to flood your room without bulky sightlines or visual clutter.
Thermally broken aluminium construction
All frames are fully thermally broken to reduce heat loss, minimise cold bridging, and improve year-round comfort.
