Korniche Flat Glass Rooflights & Flatlite Rooflights available supply only from SevenDay
Also available from the Korniche range:
Flood your home with natural light
A flat glass rooflight brings the sky into a room without changing its lines. Where a lantern rises up and adds structure, a Korniche flat rooflight sits almost flush with the roof, so the ceiling stays clean and uninterrupted while the room below floods with daylight.
A near-invisible frame
Korniche’s flat glass rooflight & Flatlite rooflights are built around a slim frame, engineered to frame the glass rather than compete with it. Fewer visible components mean an almost seamless sheet of glass from below, with the same precision engineering behind the scenes that keeps the unit weathertight and true to shape for years.
Warm in winter, cool in summer
Every Korniche flat rooflight is thermally broken, with a polyamide barrier separating the inner and outer aluminium so heat can’t transfer straight through the frame. Choose double glazing for strong all-round performance, or step up to the triple-glazed option for even better heat retention and greater solar glare reflection. A self-clean glass coating comes as standard, helping rainwater carry away dust and grime with minimal upkeep.
Made to fit your home
Every Korniche flat rooflight is made to measure, so it’s specified around the opening rather than the other way round:
- Bespoke sizes to suit the opening, from compact single units to large open-plan spans up to 6m x 4m
- Double or triple glazed, in clear, blue, or neutral tints
- Laminated glass option for added durability and safety
- Standard colours in Grey, Black, and White for fast turnaround, or a fully bespoke RAL powder-coated finish on request
Built to last
- Thermally broken aluminium frame with a low-profile black gloss frame
- Double or triple glazed units, both exceeding current Part L thermal requirements
- Self-clean glass coating as standard
- Sits on a kerb or upstand for a clean, low-profile finish on flat and low-pitch roofs
- Minimal upkeep once installed
Ask your local SevenDay advisor about adding a Korniche flat glass rooflight to your project.

Colours and glazing options
- Stock colours: Grey, Black & White for the fastest lead times
- Bespoke powder-coated RAL colour finishes available on request
- Clear, blue, or neutral glass tints
- Laminated glass option where extra durability or safety is needed
- Self-clean coating included as standard. A special coating applied to the glass breaks down organic dirt, reducing the ability of other dirt particles to stick to the surface. When it rains, water spreads evenly across the glass rather than forming droplets. This thin sheet of water then washes away the loosened dirt as it runs off. The result is cleaner glass with less maintenance and visibly clearer views.
Lantern or flat rooflight – which is right for the project?
Where a Korniche lantern adds height, dimension, and a pyramid or ridge structure to a flat roof, the flat glass rooflight keeps everything level with the roofline for a minimalist look, inside and out. It’s a strong fit for modern extensions, orangeries, garden rooms, and kitchen spaces where the priority is light without a visual statement piece overhead.
