Bright New Korniche Roof Lantern

The existing unit had seen better days—thick frames, poor thermal performance and glass that offered little protection from solar gain. In summer, the room overheated; in winter, it leaked warmth. The client’s brief was simple: install a sleek, high-performance roof lantern that would flood the space with natural light and keep it comfortable all year round.

Our surveyor attended the property in Harrow to assess the existing opening and discuss design options with the client. After reviewing the room layout, orientation and finish preferences, we recommended a Korniche Roof Lantern supplied and installed by our in-house fitting team.

Korniche was the ideal choice for this project thanks to its ultra-slim aluminium frame, excellent thermal performance and clean internal lines—perfect for transforming the room into a modern, bright and energy-efficient living space.

• Korniche aluminium roof lantern, custom-sized to the existing roof opening
• Thermally broken frame system to minimise cold bridging
• High-performance, low U-value glazing for superior insulation
• Solar control, self-cleaning glass to reduce overheating and simplify maintenance
• Powder-coated finish to complement the property’s existing windows and doors

The lantern was manufactured to measure, allowing us to use the existing aperture and avoid major structural alterations. Our installers removed the old unit, prepared the opening and fitted the new Korniche lantern with a neat internal and external finish.

The client now enjoys a bright, airy room that feels comfortable in every season.
The new Korniche Roof Lantern delivers:

• Noticeably improved warmth in the winter months

• Reduced glare and overheating in summer

• A more modern, minimal aesthetic with slim sightlines and larger glass areas

What was once a rarely used space is now a genuine focal point of the home—a versatile, inviting area for relaxing, dining and entertaining.

Roof lanterns can be a major source of heat loss and solar gain if they’re not designed with performance in mind. By installing a Korniche thermally broken lantern with high-performance solar control glazing, this Harrow homeowner has significantly improved both comfort and efficiency, while enhancing the overall look and value of the property.
