Order your roof lantern to the external kerb size, not the ceiling opening. Our sizing guide covers measuring the kerb, the right lantern for 3x3m to 6x4m extensions, one large lantern versus two, ridge height, glass weight and bar sightlines, with live Korniche size and price data.

How to fit a Korniche roof lantern from kerb to caps: upstand requirements, the four tools you need, each fitting stage in order, how long it takes, why lanterns leak and how to fix it, and Building Regulations.

Everything you need to choose a roof lantern: how it differs from a rooflight, Korniche vs Atlas vs Sheerline vs Solaris, which glass for which orientation, sizing, live prices, planning and Building Regulations, and a pre-order checklist.

What a U-value is, what's good for windows, double and triple glazing, the Building Regulations limits for windows and roof lanterns, and how the six Korniche glass options compare on U-value, solar reflection and light.

The Korniche Roof Lantern won The King’s Award for Enterprise for Innovation in 2024, awarded to its manufacturer Made For Trade. What the award recognised, the full timeline, and what it means when you choose a roof lantern.
