Engineered for a grander view
Enjoy the most expansive views possible with industry-leading maximum sizes for your roof lantern, spanning up to 24m2.
Meticulously engineered to be the strongest and stiffest on the market, it supports more glass without the need for additional rafters.
Thanks to its sturdy die-cast aluminium components and patented method of fixing the spas together, the Korniche roof lantern can span up to 3 meters by 2.5 meters for a single piece of glass per side, or up to a maximum roof space of 6 meters by 4 meters with intermediate rafters.
Bask in daylight and design
A modern take on the classic Victorian-era lantern roofs, the Korniche roof lantern comes in bespoke designs and a range of colours to transform your living space with light.
Reminiscent of traditional timber structures, its award-winning aluminium rafters and spars provide some of the narrowest internal
sightlines available, with no visible fixings and seamless joints throughout. Externally, aluminium die-cast components are covered with
contemporary sculpted top and end caps creating a continuous aesthetic whilst delivering secure and all-weather protection.
Frequently Asked Questions
What is an aluminium slimline roof lantern?
An aluminium slimline roof lantern is a glazed rooflight with ultra thin aluminium bars that flood flat roof extensions with natural light. The slim profiles maximise the glass area for uninterrupted sky views.
How slim are the bars on a slimline roof lantern?
Our slimline roof lanterns feature aluminium bars as narrow as 40mm. This creates a frameless appearance from inside and lets significantly more light into your room than traditional lanterns.
Are aluminium roof lanterns energy efficient?
Yes. Our aluminium slimline lanterns use thermally broken profiles and argon filled double glazed units with a low emissivity coating. They help keep your extension warm in winter and cool in summer.
