What is a roof lantern made of?

There are many options on the market that use different materials and have different USPs, specifically, we stock Atlas and Korniche which are aluminium structures. 

The Korniche system presents an aesthetically pleasing solution for roofing needs, boasting a high thermal performance. The Korniche roof lanterns, known for their slim and elegant design, are custom-made to fit perfectly. These lanterns have undergone enhancements to establish themselves as the most robust and durable option available. With a focus on providing an unobstructed view, the Korniche lanterns feature a minimalist structure, offering large glass spans and fewer rafters compared to alternative models. In fact, with a width of only 57mm, the spans and ridge sections are among the slimmest in the market.

Furthermore, the lantern utilises a top-quality T-bar that enhances insulation by effectively sealing the gap between the profiles and the finishing caps, further improving the thermal break of the roof lantern. This meticulous design ensures exceptional thermal efficiency, eliminating cold bridges between external and internal profiles. The Korniche systems also feature top-of-the-line seals and gaskets, guaranteeing weatherproofing capabilities even in the harshest conditions.

Combined with high-performance double glazing, these lanterns minimise heat transfer to an impressive extent. To suit various interior and exterior preferences, a range of self-cleaning glass options with exceptional performance are available, including blue, aqua, bronze, tinted, neutral, and clear glass. The glass options boast U-values ranging from 1.0 to 1.2, reflecting their energy efficiency.

The standard colours offered for the Korniche system are White Gloss, Anthracite Grey Matt, and Jett-Black Matt. Additionally, the option for a bespoke colour of your choice is also available, ensuring a personalised touch to complement any architectural vision.

FAQ’s about roof lanterns

Do you need planning permission to install roof lanterns?

In most cases, obtaining planning permission is unnecessary when installing a roof lantern, as long as you adhere to the permitted development guidelines below:

  • 1. The roof lantern should not protrude more than 150mm beyond the sloping plane of the current roof.
  • 2. The height of the roof lantern should not exceed the highest point of the existing roof.
  • 3. If the roof lantern is positioned on a side elevation roof slope, it must incorporate obscure glazing.
  • 4. Unless the height is at least 1.7m above the floor, no openings are permitted in the roof.

By following these permitted development rules, you can typically proceed with installing a roof lantern without the need for additional planning permission.

However, every project is different and we recommend speaking to your local council or planning officer to check on this before going ahead.

Can you add a roof lantern to an existing roof?

If you are incorporating a roof lantern into a new extension or a new house construction, compliance with building regulations should be addressed as part of the overall project.

However, if your intention is to install a roof lantern into an existing roof, it is necessary to obtain approval from building control and undergo inspection. Ensuring the structural integrity of the roof lantern opening is crucial, as it may require rearrangement of the roof joists to accommodate the new addition.
