Korniche is a premium roof lantern brand known for stunning design, meticulous engineering and durability, built to enhance any home while withstanding the worst of British weather.

Yes. Korniche roof lanterns reduce reliance on electric lighting and improve ventilation. Available with double or triple glazing, they minimise heat transfer and help maintain a more stable, efficiently heated interior.

Korniche roof lanterns are available in both opening and fixed styles. Opening versions create a strong natural updraft that cools and dries your home, significantly improving ventilation.

It depends on the style and glass type. Walk-on glass can support an adult's weight but must be specified at the time of ordering. Unless there is a genuine need, it is better to keep people off the roof lanterns entirely.

Most are reasonably straightforward to clean, though reaching them is often the main challenge. If you are uncomfortable with heights, a fully insured professional window cleaning company is the safest option.

Planning permission is usually required if the roof lantern rises more than 15cm above the roof surface. It will also almost certainly be needed for listed buildings or properties in conservation areas.

We don't currently offer installation, but we can recommend a reliable contractor and provide detailed installation instructions with every Korniche roof lantern purchased.

Korniche rooflights are known for their slim sightlines, lightweight but strong aluminium construction and modern design ethos. As such, they are a great choice for both residential and commercial settings.

Not generally. They are usually installed on flat roofs on top of an insulated upstand to help ensure their weatherproof capabilities. This insulated upstand makes them a less-than-ideal choice for pitched roofs.

Yes, Korniche roof lanterns are very energy-efficient. They achieve this enhanced energy efficiency by allowing in more natural light, as we mentioned, but also by way of their insulated frames and efficiency seals.

Absolutely! Korniche roof lanterns are a popular choice for kitchen and living area extensions. Their clean lines and ability to allow more natural light in help to create brighter, more welcoming spaces.

Yes, Korniche roof lanterns are available in a wide range of standard sizes suited to meet the needs of most roof openings and layouts.

No. There is very little maintenance required for Korniche roof lanterns other than the occasional cleaning and annual checks of the seals and glazing.

Of course. Korniche roof lanterns sold in the UK must, by law, comply with all relevant safety, structural and thermal rules and regulations governing rooflights, roof lanterns and skylights.

Ultimately, it is up to the homeowner or developer to determine if Korniche roof lanterns are a wise investment. But from feedback we get at RLRL, customers seem well pleased with the energy-efficiency they produce, their modern, sleek design and their durability.
