The Korniche roof lantern comes with self-cleaning glass in a range of shades giving overall U values as low as 1.2, so you can enjoy, diffuse or direct natural light while keeping the heat in your home. The dedicated roof glazing used also reduces the amount of heat that enters your living space, helping to maintain the perfect temperature and level of light.
The roof lantern is fully thermally broken. This means the outside aluminium elements are connected to the internal ones through thermal breaks.
These include polymer T bars between the internal and external parts of the spars and polyamide thermal breaks in the eaves beams. This vastly reduces heat transfer and ensures any cold bridging is virtually eliminated. Industry-leading Q-Lon seals combine and complement the thermally broken design to protect your home from the elements. An
innovative glass lock stops the glass slipping under its own weight delivering integral strength and ensures a lifetime of low maintenance.
Making the complicated simple takes real creativity. Our smartly engineered roof lantern is the only design on the market that requires no cutting, trimming or silicone sealant within the lantern structure whilst being assembled.
Capable of being fitted in minutes and glazed in seconds, the Korniche roof lantern is the fastest and easiest system to install on the market. It arrives with a comprehensive installation manual that has simple step by step instructions that could not be easier to follow. The sheer simplicity of the installation means that any competent tradesperson can safely, quickly and securely fit your lantern, eliminating the need for specialist installers. An installers dream.
