Installing a Korniche Roof Lantern is one of the most effective ways to transform a space with natural light, modern styling and exceptional thermal performance. Whether you are a homeowner wanting to understand the installation process, or a professional installer preparing for the job, this guide provides a balanced and comprehensive walkthrough. Korniche lanterns are known for fast, accurate installation and engineering precision — but correct preparation and careful assembly remain essential for achieving a flawless finish. Explore our full range of Korniche Roof Lanterns.
Understanding the Korniche System
The Korniche Roof Lantern is engineered using thermally broken aluminium, high-performance glazing and accurately machined components. This design delivers outstanding rigidity while maintaining slim, elegant sightlines. For installers, this means fewer parts and a quicker installation. For homeowners, it means maximum daylight, cleaner aesthetics and excellent energy efficiency. Before starting, always check the manufacturer’s instructions and ensure all parts are present and undamaged.
Preparing the Roof Opening and Upstand
A precise, well-built upstand is the foundation of a successful installation. This timber kerb must typically be at least 70mm wide and raised around 150mm above the finished roof level to meet building regulations.
Ensure that:
- The internal upstand dimensions match the ordered lantern size
- All sides are level, straight and perfectly square
- The roof membrane is correctly installed and fully weatherproof
For deeper technical guidance, see our roof lantern upstand requirements page.
Positioning the Eaves Beam
The eaves beam forms the outer frame of the lantern and must be positioned with precision. Steps:
- Lay each eaves beam section on the upstand.
- Align the mitred corners so they meet cleanly without gaps.
- Fix the beams securely using suitable screws for the roof structure.
- Fitting the Rafters and Ridge
Once the perimeter frame is secure, the Korniche system allows rapid assembly of the structural elements.
Steps:
- Insert the ridge section into the central slot on the eaves frame.
- Position each rafter into the pre-engineered connection points.
- Tighten all fixings evenly, checking alignment as you go.
Installing the High-Performance Glazing
Glazing is crucial to thermal and aesthetic performance. For more detail, visit our roof lantern glass
