Updated April 2026

Sterlingbuild is proud to present the latest Korniche Roof Lanterns and Korniche Flat Lite roof windows, premium, contemporary glazing solutions designed to flood your space with natural light while delivering exceptional thermal performance and refined aesthetics. 

Engineered for modern living and trusted by homeowners, builders and architects across the UK, Korniche products combine innovation, style and structural performance.

The New Korniche Roof Lantern Range 

The latest Korniche lantern system builds on the brand’s reputation for precision engineering and elegant design. With ultra-slim aluminium profiles and impressive spanning capability, these lanterns create bright, open interiors without compromising strength or insulation. 

Available Upstand Options 

The new Korniche lantern is available in three distinct configurations, allowing you to choose the perfect solution for your project: 

• Builder’s Upstand Use with a site-built upstand, ideal for bespoke builds and experienced installers.
• 150mm Insulated Upstand Factory-made insulated upstand for improved thermal performance and quicker installation.
• 300mm Insulated Upstand Deeper insulated upstand offering maximum insulation, ideal for high‑performance builds. 

Optional LED Lighting

All Korniche lantern options can be upgraded with integrated LED lighting, providing subtle illumination and enhancing the lantern’s architectural impact both day and night. 

Standard & Bespoke Sizes Explained 

• Standard Sizes
  - Korniche roof lanterns are available in a wide range of standard sizes, making them an ideal choice for common flat roof openings and extensions. 
  - Designed to suit the most popular roof apertures 
  - Faster lead times compared to made‑to‑order options 
  - Cost‑effective without compromising on quality or performance 

Standard sizes are perfect for kitchen extensions, living spaces and refurbishment projects where speed and simplicity are key. 

• Bespoke Sizes
  - For projects that require something more tailored, Korniche roof lanterns can also be manufactured in bespoke sizes. 
  - Made to order to suit your exact roof opening 
  - Ideal for large, open‑plan extensions and architectural features 
  - Available up to a maximum size of 6m x 4m 

Bespoke sizing allows complete design flexibility while maintaining the slim profiles and structural integrity Korniche is known for. 

Glass Pane Configuration 

Up to 4 Glass Panes. Most standard and many bespoke Korniche roof lanterns are designed using up to four panes of glass, which provides: 

• Clean, balanced sightlines
• Maximum light transmission
• A refined, symmetrical appearance 

Larger Lanterns (More Than 4 Panes)

When lanterns increase in size beyond certain spans, more than four glass panes may be required. This is done to: 

• Maintain structural strength
• Ensure safe glass sizes
• Preserve long‑term performance and durability 

The exact pane configuration depends on the overall size and proportions of the lantern. Sterlingbuild will advise on the correct design to ensure your lantern meets performance and safety requirements.
