What makes Korniche roof lanterns special

An all aluminium astonishingly beautiful roof lantern, a successful blend of contemporary, yet classic design with cutting edge engineering. Strongest and most thermally efficient in its class, yet quick and simple to install.

Multiple configurations

All lantern roofs are bespoke and made to order to your exact specifications, up to a massive 6 x 4 meters external size. The pitch is fixed at 24° degrees.
Here is our unique on-line aluminium roof lantern designer.

Maximize natural light

The slimmest profiles, at only 57mm wide for spar and ridge sections. Concealed fittings with unbroken sight lines. Patent pending die cast ridge and spar end bosses to maintain the slick aesthetics. Hidden fixings cleverly concealed.

Fast installation

Quick and easy to install, 4 times faster, due to pre-drilled eves beams, all-in-one glazing retainers, one bolt spars and clip fit top & end caps. Please see the Korniche installation manual for details.

Self-cleaning glazing

To help clean the outside glazing, we offer several types of Pilkington Self-Cleaning glass (video) at low u-ratings at various degrees of reflecting solar heat, certified to EN 1096-5, the new European Standard for self-cleaning glass. See the Glass brochure for more.

Class leading thermal performance

Unlike traditional roof systems that use an aluminium T-bar, Korniche uses a PVC T-bar and polyamide interior to the eaves beams to 100% thermally break the inside and outside aluminium profiles for excellent thermal efficiency. Complete roof u ratings from 1.2 W/m²K (tested on a 3 x 1.5m roof with 1.0u glazing).


Every component has been meticulously optimized to create the stiffest and strongest roof lantern assembly on the market. Unparalleled strength, Korniche is capable of supporting loads of up to 3.5kN/m2 to withstand the worst of the UK weather.

Award winning

Since Korniche was launched it has won several awards.
Come and see for yourself at one of the main Homebuilding & Renovating Shows at Birmingham NEC, London ExCel or the Northern show at Harrogate.
