What is a Flat Roof Light?
A flat roof light is a fixed glazed panel that sits within your flat roof structure.
Unlike roof lanterns, which add height and dimension, flat roof lights keep a minimalist, clean line inside and out.
Perfect for modern extensions, orangeries, garden rooms, and kitchen spaces where light matters but subtlety wins.
But not all roof lights are created equal. Enter the Korniche Flat Roof Light: a game-changer built with precision-engineered aluminium and thermal performance at its core.
Designed from scratch (not adapted from conservatory kits), it delivers powerful results with a sleek, streamlined look.
Why Choose the Korniche Flat Roof Light?
When you’re choosing a flat roof light, it’s easy to get caught up in specs and sales talk—but with Korniche, what you see is real engineering brilliance that backs up every claim.
Built from the ground up with homeowners, installers and designers in mind, the Korniche Flat Roof Light is more than just a pretty face.
🌍 Slim Sightlines, Maximum Sky Views
Natural light transforms a space—but only when it’s allowed to flow freely.
Korniche’s ultra-slim aluminium frame sits virtually flush with your internal plaster line, creating that sleek, almost frameless look.
The result? An uninterrupted view of the sky from inside your home that adds instant atmosphere and architectural flair.
❄️ Industry-Leading Thermal Performance
Unlike older or less efficient flat roof lights, Korniche is built for the British climate.
Its fully thermally broken frame and low-E, argon-filled glazing panels provide U-values as low as 1.2 W/m2k.
That means your home stays warmer in winter, cooler in summer—and your energy bills stay pleasingly low.
🔧 Strong, Secure and Low Maintenance
Thanks to its robust die-cast aluminium components, the Korniche frame is exceptionally strong yet lightweight. It’s designed to support large panes of glass without extra reinforcement.
Plus, the self-cleaning glass and weatherproof powder coating mean less upkeep and long-term peace of mind.
✅ Simple Installation
Time is money, especially on a build. Korniche’s unique design allows the unit to be fitted in minutes and glazed in seconds.
No trimming. No internal silicone sealing. Just a clear step-by-step process that makes life easier for you (or your builder) and guarantees a perfect finish every time.
🛠️ Built in the UK, Designed to Last
Every Korniche roof light is made in the UK to rigorous standards.
It’s backed by high-quality materials, CNC precision cutting, and strict quality checks—so you can feel confident you’re investing in a roof light that will perform brilliantly for years to come.
Korniche vs Other Flat Roof Lights
Wondering how Korniche stacks up to other big names like Atlas? Here’s the lowdown:
| Feature | Korniche | Atlas |
| U-Value | 1.2 W/m2k | 1.4 W/m2k |
| Sightlines | Frameless internal look | Slimline, but visible |
| Frame Material | Thermally broken aluminium | Aluminium with thermal breaks |
| Glass | Self-cleaning, solar control | Self-cleaning, solar control |
| Colours | Dual and custom RAL | Dual and stock options |
While both are great options, Korniche roof lights go that little bit further in efficiency and visual impact.

FAQs
Are flat roof lights energy efficient?
Yes, especially with a high-spec system like the Korniche Flat Roof Light.
With U-values as low as 1.2 W/m²K and solar control glazing, they help maintain consistent indoor temperatures all year round—saving you energy and money.
What size roof light do I need?
That depends on the space and how much light you want to let in.
The Korniche roof lights are made to order, so you can customise them to fit your exact opening. A popular size for kitchen extensions is around 1000mm x 2000mm, but they go much larger too.
Can flat roof lights open for ventilation?
The Korniche Flat Roof Light is a fixed unit, so it doesn’t open. If ventilation is a must-have, you might consider combining it with other window options or looking at lanterns with opening vents.
How long does it take to install a Korniche roof light?
Thanks to its unique design and pre-assembled components, a Korniche roof light can be installed in minutes and glazed in seconds by a competent tradesperson. No internal sealant, trimming, or specialist tools required.
Can you put a roof light in a flat roof?
Yes, you can—and flat roofs are ideal for it. Just make sure your builder installs an upstand (a 70mm timber kerb) to support the roof light.
Do I need planning permission to put a skylight in my roof?
Not usually. As long as the roof light doesn’t protrude more than 150mm from the roof plane and isn’t within 2m of a boundary, you’re covered by permitted development. Always confirm with your local authority to be safe.
How to measure Korniche roof lights?
Measure the external kerb size (including the timber upstand). Korniche units are designed to drop perfectly onto this with no trimming required.
