Roof Lantern

If you’re looking for the best classic or modern look designed the way you want…

Our roof lanterns have classic timber lines and are constructed from the best in modern materials. You have freedom to configure the strong, slender and carefully detailed rafters to create a bespoke design within the system parameters. If you’re going classic you can have symmetrical rafters with smaller glass spans and if you want to go modern, you can specify minimal rafters giving some of the biggest glazing spans available.

If you’re looking for a wide choice of colours and finish…

You can choose any dual or single colour permutation of our standard colours. Want something more individual?
The roof can be supplied in any RAL colour you wish, in both single or dual but may take a little longer to be installed.

If you’re looking for the strongest roof on the market…

Engineered to be installed in the harshest environments at sizes up to 6m x 4m you can rest assured that what’s on the outside stays out, whilst its fully thermally broken construction keeps your family warm inside.The roof lantern has been optimised to create the strongest and stiffest roof lantern possible with minimal structure to obscure your view and let light flood in to your home. Unparalleled in strength, it can survive whatever nature throws at it. Put into perspective a 6mx4m roof lantern can support over 8 tonnes.

More Glass, Less Roof

Design optimisation ensures that it has the largest glass spans and fewest rafters currently available from any other system on the market.

Highest Quality Weatherproofing

Providing the last word in weather protection we use the best seals and gaskets available throughout, ensuring complete peace of mind in the most extreme conditions


Our innovative glass lock system and tamper proof fasteners keep everything tightly in place and once finishing capping’s are fitted, there are no visible fasteners anywhere to be seen


The thermal efficiency of our roof has been guaranteed by the elimination of cold bridging, achieved by isolating of the external profiles from the internal ones. Combined with high performance glazing, the ability to reduce heat transfer is in a class of it’s own. With complete roof U values from 1 to 1.2w/m2K Korniche provides your home with a room that’s comfortable all year round.

Thermally Broken Eaves Beam

Thermal efficiency starts at the bottom of our roof. Eaves beams are fully thermally broken to create an insulated barrier between the aluminium sections

Insulating T-bar

Our in-house designed high quality insulating T-bar bridges the gap between the profiles and the aluminium finishing caps to create the largest possible thermal break

Performance Glazing

This can be supplied with a range of high performance self-cleaning glass options to suit every taste. To complement your new roof you can choose from either blue, aqua, bronze, tinted, neutral or clear and with U values ranging from 1.0 – 1.2



Slim sections – at only 57mm wide, the spas and ridge sections are amongst the slimmest on the market. Coupled with our sculpted bosses they provide a look usually associated with hand crafted timber constructed lanterns.

Traditional meets Modern

Narrow yet deep structural profiles and detailing along with lower edges provides a clean classic feel with modern high performance materials

Hidden Fixings

Fully concealed fixings ensure sight lines flow gracefully and uninterrupted throughout bringing unrivalled elegance and balance

Range of Colours
