Bespoke Roof Lanterns

Roof lanterns are one of the most impressive looking rooflights on the market, giving the impression of a higher ceiling and larger room. Getting the size right with these modern architectural wonders can be difficult, which is one of the reasons why our bespoke aluminium lanterns are so popular.

Korniche roof lanterns offer unrivalled views of the sky above. The lantern's slim stucture means you can enjoy gazing up at the stars with little obtrusion from any frame, while the level of sunlight allowed into the home is greatly enhanced, keeping your space bright, temperture comfortable and bills down.

Installing Korniche roof lanterns is an easy process, with complete installation achievable in under half an hour.

Customisation on roof lanterns includes multiple combinations of internal/external finish, several types of glazing type and glazing finish, the latter of which there are six variants to pick from including clear, blue/bronze tint and privacy.

Bespoke lanterns are also available from REAL, another British brand who like Korniche specialises in manufacturing roof lanterns that are durable and high performing. REAL’s aluminium roof lanterns are even slimmer, meaning less frame and more light.

Bespoke upgrades on our REAL aluminium lanterns include a choice of RAL colours, glazing and any dimensions you desire.

One of the biggest draws of these roof lanterns comes in the discount package available when you purchase your lantern alongside aluminium doors and an aluminium window, a multibuy offer that could save you hundreds of pounds on your extension project.
