The Korniche Roof Lantern is without doubt, the best value aluminium roof lantern on the market and provides looks and performance head & shoulders above any similar priced competitor.


The published prices are for contemporary roof lanterns up to 2500mm wide x 3000mm long and feature ridge & hip sections, but no intermediate bars. Other sizes are available upto 6000mm long subject to width. This provides a light & airy structure making the most of the glass area without interruption. However, if you prefer a more traditional appearance, please let us know and we will include for glazing bars typically spaced at 600 to 900mm centres.


Stay comfortable all year round – A range of glass choices is available including Neutral Solar Control Glass at no extra cost. This cuts down the sun’s heat by about 60%, but the slight neutral tint still lets in plenty of light resulting in a bright room without glare. A special low-emmissivity 1.2W/m2.K coating retains heat meaning you always stay cozy during the coldest winter months. Korniche Roof Lanterns are manufactured from thermally broken aluminium, foam filled gaskets and insulation to reduce the risk of condensation.


Each Roof Lantern kit comes with easy to follow instructions and is designed for quick assembly rarely taking more than half a day to install. Glass is supplied loose making them ideal for projects where access is restricted as the frame is supplied in knock-down kit form and provided in easy, handy-size bundles.


The neat, slim aluminium profiles are finished with a durable polyester powder coating finish which is virtually maintenance free. Our roof lanterns can be finished a variety of standard combinations (see the drop down menu above) or any standard RAL Colour. Self-cleaning glass comes standard to ensure easy maintenance all year round.


The Korniche Roof Lantern is designed with a fixed pitch of 25 degrees and is always designed with hips both ends. If you require something different, then you may want to consider our SpanGard Roof Lantern which has more flexibility in terms of pitch, length, width and glass spec.
Our SpanGard Roof Lanterns offer greater design flexibility with variable pitch, shapes and glass specification. Hipped or Gable Ended, Spangard Roof Lanterns are available upto 6000mm wide by infinite length and are suitable for high end domestic or commercial applications. Manufactured from thermally broken aluminium, octagonal, pyramid, hexagon, multi-faceted or irregular shaped roof lanterns are all possible. You can find more details here.


If the height above floor level exceeds 5M, please contact our Technical Department as glass specification likely will need to be upgraded in order to comply with Building Regulations.

    10/10 in terms of product and service. I have dealt with Lonsdale for many years and this new roof lantern is another example of the quality you can expect from this very professional company. Please pass my wishes to Nigel and wish him a long and happy retirement.

    Would have given 5 stars, but glass turned up 2 days late. Having said that, I was kept well informed, but these days service is key in this competitive market.

    Don’t know how they do these roof lanterns at the price they do, but I am pleased they do. I have fitted countless roof lanterns in my time, but these are a dream to install and look the dogs whatsits!
