Why choose a Korniche roof lantern?

The Korniche is the UK's market-leading aluminium roof lantern, holder of a King's Award for Innovation and designed as the fastest-to-fit lantern on the market. Its thermally broken aluminium frame, advanced polymer thermal breaks and fully insulated joints make it warm and structurally rigid, while a unique spar-tensioning system keeps the slim sightlines tight and weather-tight. Glazed with 28mm argon-filled, self-cleaning glass, secured to PAS24 as standard and backed by a 10-year warranty, it's a premium lantern that still fits fast and cleanly.

Rectangular or pyramid - and how big can it span?

The Korniche comes in rectangular and pyramid configurations at a fixed 25° pitch. Choose pyramid for square or near-square openings and rectangular for extensions and orangeries. Sizes run up to 6m × 4m for the largest rectangular unit (4m × 4m pyramid), giving large, uninterrupted glass spans with minimal frame. Measure the finished builder's kerb the lantern will sit on, not the ceiling opening, and we'll help you to confirm the size.

What are the Korniche glazing options?

All Korniche glass is 28mm double-glazed, argon-filled and self-cleaning as standard, with laminated and privacy options available. There are six glass specifications, from Clear (maximum light) through to solar-control Blue and the Premium coatings (best solar control and warmth). South-facing rooms may benefit from a higher solar-reflection glass to limit overheating; north-facing rooms usually want Clear for brightness. Note the Korniche is double-glazed only and there is no triple-glazed option.

Can the Korniche have LED lighting?

Yes, it can be specified with fully integrated, dimmable LED lighting and a matched diffuser lens that hides the strip when off and softly lights the frame when on.

Can a Korniche roof lantern be opened?

No, the Korniche is a fixed (non-opening) sealed lantern, which is what keeps its thermal performance and weather-tightness at their best. If you need ventilation, pair it with a separate opening rooflight; see our opening windows range.
