How are the roof lanterns made?

The Korniche roof lantern features a revolutionary aluminium design that comes with pre-fitted injection moulded silicone seals and Q-Lon gaskets. This means your roof lantern installer only needs to apply silicone sealant to the underside of the eaves beam to weather seal the unit to the upstand of your roof extension.

Alongside the award-winning frame design, Korniche lanterns can be supplied with a range of high performance self-cleaning glass options to suit every taste.

The market leading Korniche Aluminium Glass Roof is the only lantern that requires no cutting, trimming or silicone sealant to build the roof on site.

What is the thermal efficiency of a roof lantern?

The Korniche’s ability to reduce heat transfer is in a class of its own. The thermal efficiency of each roof lantern is guaranteed by the elimination of ‘cold bridging’ (a technique of isolating the external profiles from the internal ones)

Combined with high performance glazing and complete roof U values from 1.2w/m2K Korniche roof lanterns provide your home with a room that’s comfortable all year round.

Performance Glazing
Korniche can be supplied with a range of high performance self-cleaning glass options to suit every taste. To complement your new roof you can choose from either blue, aqua, bronze, tinted, neutral or clear and with U values ranging from 1.0 – 1.2.

Thermally Broken Eaves Beam
Thermal efficiency starts at the bottom of each roof. Eaves beams are fully thermally broken to create an insulated barrier between the aluminium sections.

Insulating T-bar
Our in-house designed high quality insulating T-bar bridges the gap between the profiles and the aluminium finishing caps to create the largest possible thermal break.

How easy is it to install a roof lantern?

Along with pre-fitted injection moulded silicone seals and Q-Lon gaskets the installer only needs to apply silicone sealant to the underside of the eaves beam to weather seal the unit to the upstand of your roof extension.

How strong are roof lanterns?

The Korniche Roof Lantern has been optimised to create the strongest and stiffest roof lantern possible with minimal structure to obscure your view and let light flood in to your home. Unparalleled in strength, the Korniche can survive whatever nature throws at it. Put into perspective a 6mx4m roof lantern can support over 8 tonnes.

More Glass, Less Roof
Design optimisation ensures that Korniche has the largest glass spans and fewest rafters currently available from any other system on the market

Highest Quality Weatherproofing
Providing the last word in weather protection Korniche uses the best seals and gaskets available throughout, ensuring complete peace of mind in the most extreme conditions

Security
Our innovative glass lock system and tamper proof fasteners keep everything tightly in place and once finishing capping’s are fitted, there are no visible fasteners anywhere to be seen

How do you measure for a Korniche roof lantern?

The Korniche Roof Lantern is bespoke product made to your exact sizes. We work from external measurements and recommend a minimum 70mm wide upstand is used.

To calculate your required size, you will need to measure the length and width from the outside edge of your timber upstand. Please allow 6mm on each side to allow for rainwater drippage.

If you have a roof opening but upstands are not built yet, you will need to measure the length and width of your roof opening and add 140mm to both dimensions to allow for your upstands. This will give you the external dimension of your roof light.

Further details can be seen on our roof lantern measuring guide.

What glazing options are available for roof lanterns?

Our Korniche roof lanterns come with different glazing tints and U-values.

1.2 U-value glazing is the equivalent to double glazing, and can be supplied in Clear, Blue and Neutral.

Our 1.0 U-value glazing is the equivalent to triple glazing, and reflects 85% of the solar glare. This can be supplied in Sunshade Blue or Aqua.

What guarantee comes with the Korniche roof lantern?

All of our Korniche Roof Lanterns are covered by a 10 year manufacturers guarantee with Korniche.

What size of roof lanterns are available?

All Korniche roof lanterns are made to measure and can be made any size from the smallest (850mm x 850mm) to the largest (6000mm x 4000mm) 

If you’re having trouble deciding, your interior designer or Korniche roof lantern installer can advise on the best size!
