How We Install a Korniche Roof Lantern – Professional Fitting in One Day

Installing a Korniche Roof Lantern is a precise job best left to experienced installers (like us!), but here’s a clear overview of how it’s done:

1. Pre-Installation Check -We confirm the structural opening is correct (usually a pre-prepared upstand/kerb built by your builder to Korniche’s exact specifications).
2. Lantern Assembled onsite -One of the big advantages – The roof lantern is fully assembled onsite making it easy to get onto the roof for the team and narrow access areas
3. Lift & Position -The lantern is carefully lifted onto the upstand (by hand  and perfectly centred.
4. Secure & Weatherproof
   • Fixed to the upstand using heavy-duty brackets and stainless-steel fixings
   • High-performance thermal tape and sealant applied between lantern and upstand

1. Final Checks & Clean -All glass cleaned, and a full weather-tightness inspection carried out.

Most domestic Korniche lanterns are fully installed and watertight in 2-3 hours with minimal mess and no need for scaffolding.
