Powder coating
The lantern’s powder coated exterior doesn’t just offer a wide range of colours, it also delivers a thicker, more consistently smooth finish when compared to standard finish.
Powder coating results in an extremely durable finish and is also much kinder to the environment.

Self-clean glass

Once installed, your powder-coated, glazed lantern will be fully weather resistant, with self-cleaning glass to reduce maintenance even further.

Specially designed to remain cleaner for longer, our self-cleaning glass features a transparent coating that breaks down dirt using the sun’s ultra-violet rays, which is then washed away by any rain.
The highly durable coating is integrated into the external surface of the glass. It will still require the occasional clean in line with the glass  manufacturer’s instructions, but at far longer intervals compared to conventional glass.

RAL Colours

We offer more than 150 colours in matt, satin or gloss, including the option to have different colours on the inside and outside of the frames.

This gives you greater freedom to match both the interior and exterior style of your property.

Die-cast aluminium components

Because we use aluminium, our die cast components are made with greater accuracy and tighter tolerances that deliver superb weather resistance and thermal retention, low maintenance and breath-taking aesthetics.

Strongest on the market

Meticulously engineered to be the strongest and stiffest on the market, our roof lantern supports industry-leading maximum glass sizes without the need for additional rafters.

Victorian-inspired ridge and spas

Reminiscent of traditional timber structures, our roof lantern’s rafters and spas provide some of the narrowest sightlines available, ensuring you can enjoy a grander view.

Seamless aesthetics

With no visible fixings and seamless joints throughout, your roof lantern doesn’t just change the way your living space looks. It changes how it feels.

Every detail designed for purpose

The Korniche roof lantern’s simple design means it is capable of being fitted in minutes and glazed in seconds. It is the fastest and easiest kit to install on the market.

Protected inside and out

The roof lantern is fully thermally broken. Outside aluminium elements are connected to the internal ones through thermal breaks, vastly reducing heat transfer.


What is Ambi ‘self clean’ glass?

The Ambi range of self cleaning glass combines both self cleaning and solar control properties, making them highly desirable amongst homeowners looking for the ultimate in glass solutions. The coating that is applied to the glass breaks down organic dirt and by doing so reduces the adhesion of inorganic dirt. Water droplets are spread out to form a sheet and this picks up the loosened dirt particles as it drains off the surface. The result is remarkable and a difference you can actually see.

What does U Value mean?

Thermal transmittance, also known as U-value, is the rate of transfer of heat through the glass. It is measured as watts per square meter Kelvin or W/m²K. The better the insulation, the lower the U-value is.

Why does aluminium need to be thermally broken?

Aluminium like all metals is a conductor of heat. If our profiles weren’t thermally broken the inside heat would be wicked away and lost to the colder outside. By creating a profile assembled with polyamide sections between the inside and outside portions, the ‘thermal bridge’ is stopped. Polyamide is a glass filled plastic meaning it is an insulator and therefore there is virtually no conduction of heat through it.

What are the benefits of powder coat verses wet paint?

Powder coating provides better performance than wet paint—it is more resistant to chipping, scratching, and other wear because of the thermal bonding it undergoes during curing, and because it can be applied in much thicker layers. This performance is especially important for outdoor products, like aluminium glazed products.

In addition to its physical toughness, powder coating provides superior colour retention. Long term exposure to moisture, sunlight, and heat breaks down the resins found in both paint and powder coating. This process, known as chalking, causes resin and pigment particles to lose adhesion. Affected particles form a chalk-like layer on the coating surface.

The early stages of chalking merely give the coating a faded appearance, but severe chalking will eventually erode the coating enough to compromise surface protection. The rate of chalking depends on the resiliency of the resin. Polyester based powder coatings are frequently used as topcoats due to their exceptional chalk resistance.
