Glass Lock
System
This revolutionary glass lock system guarantees long-term security and little upkeep as it prevents the glass from sliding due to its own weight once set up
Korniche: Beautiful from every angle
To finish off the spas, an aluminium die-cast end cap is installed. This has been carefully crafted to fit without any visible fixtures, thus maintaining the desired aesthetic of every single detail.
Korniche: Square'Pyramid'Lanterns
Korniche: Square 'Pyramid' Lanterns
Homeowners often choose, the modern pyramid design of a square roof lantern for its precisely squared openings, or even for two distinct lanterns rather than a single larger one.
The square roof lantern offers a contemporary pyramid design. This is popular with homeowners who want perfectly square openings, or perhaps two lanterns separated instead of one larger one.
To reduce heat transfer, external aluminium components are connected to internal elements through thermal breaks in the roof lantern, creating a full thermal barrier.

Assembling the Korniche lantern takes no cutting, trimming or silicone sealing; even a proficient tradesperson can install it in a matter of minutes and finish glazing in no time. Thus, specialised installers are unnecessary.
Homeowners desring the pinnacle in glass solutions are often drawn to the Ambi line of self-cleaning glass, boating both self-cleaning and solar control properties. An applied coating deteriorates orangic dirt, which lessens the hold of inorganic debris. Furthermore, water droplets expand into a thin layer, and as it streams down, it carries away any unhinged dirt particles - making for a striking result that is visually evident.

Measuring Guide for Korniche Aluminium Roof Lanterns
The essential measurement is the external kerb, as shown in the above diagram. Looking at the base (or kerb) that the lantern is going to be fitted to, this outside measurement is the one that we need on both length and width.
The kerb is typically built out of timber, and the ideal width is 80mm. Please note the absolute minimum kerb width is 67mm.
Do I need to consider ventilation with my roof products?
Ventilation is not usually required with roof products, as this is taken care of mainly through windows, doors and air bricks. If ventilation in the roof is required (or is your preference), then a lantern is the best option as we have a choice of manual and remote-operated roof vents. Roof lights are always fixed and cannot be opened.
Are your roof products easy to fit?
Our roof products are designed to be easy to fit for people with DIY experience and experienced tradesmen. Roof lights come pre-glazed for easy installation and roof lanterns come with illustrated instructions and clearly labelled, pre-cut parts. However, it is always wise to have the products fitted by somebody with experience present.
Please also remember that the product can require several people to lift the heavy glass units, and working at a height always requires appropriate health and safety measures are observed.
I live in a coastal area, are your roof products suitable?
Yes, we can offer marine-grade upgrades for customers who live within 10 miles of the coast.
What is the best energy rating you can offer?
The best energy rating we can is a roof lantern with 44mm triple glazing, which can achieve a U value as low as 0.6.
How do I clean the roof products?
The glass itself should be cleaned in the normal way, with a soft sponge and warm water with mild detergent. As some roof products may have restricted access we offer self-cleaning glass as standard, which has a coating on to help remove dirt particles when rainwater hits it.
Do I need planning permission for my roof products?
Planning permission is not typically required to install a roof lantern or roof light. Both products are usually considered as permitted development providing they meet the following criteria:
The roof lantern/light must not protrude any higher than 150mm from the existing roof plane.
The roof lantern/light must not be any higher than the highest part of the house roof.
Any side facing windows must be obscure glazed and any openings must be 1.7m above the floor.
The above restrictions are for alterations to houses, and there are slightly different guidelines for flats, maisonettes, and converted houses. As ever, advice on planning permission is always subject to change, so always check with your local council or building authority, and exercise particular caution if you live in a conservation area or listed building.
How do I know what accreditations I need before ordering my roof products?
For new builds and extensions, the products will need building regulations consent and must meet the current recommended minimum requirements. Further accreditations such as document Q, PAS24 and Secured by Design may not be essential, but check that your architect or authority have not specified this.
Do you offer lean-to roofs?
Lean to roofs are not part of our standard range, but we can supply them by special request. Please refer to our Atlas brochure for information on lean-to roofs. If you are interested in a quote, please send to our sales team.
What glass options do I have for roof products?
Below are the different glass options explained, along with when they might be suitable. We default to A rated glass standard.
Celsius Elite - High-performance glass with a blue tint and easy clean coating. The most energy-efficient glass on the market today, and the highest performing.
Self Cleaning Clear - Clear glass with a self cleaning coating.
Self Cleaning Blue - Blue tinted glass with a self-cleaning coating.
Self Cleaning Neutral - A neutral tinted glass with a self-cleaning coating.
Self Cleaning Blue 44mm triple glazed - As above but 44mm triple glazed (better energy rating than double glazed).
Self Cleaning Neutral 44mm triple glazed - As above but 44mm triple glazed (better energy rating than double glazed).
How do I know your roof products are good quality?
We only use industry-leading brands for our products, which is especially important when considering roof lanterns or roof lights as they can vary greatly in quality. We proudly display every brand we supply, and any research into these brands will confirm they are of impeccable quality.
It is important to choose a reputable roof product, as once installed it can be problematic to carry out remedial work. Our roof products are not only considered the strongest on the market, but they are renowned for their ease of installation (all parts are cut and clearly labelled with illustrated installation instructions).
What is the difference between a ‘regular’ roof lantern and a ‘contemporary’?
A contemporary roof lantern will not have any roof bars between the four sections, so you are left with four panes of glass. This is great for maximum glass area, but it does mean these roofs have a size restriction of 1500mm in width and 3 metres in length.
A regular roof lantern is more of a traditional look, and will have roof bars in each of the four sections. The number of roof bars depends on the overall size, which is why we always provide a detailed CAD drawing once your order is placed. For this reason, regular roof lanterns can be made in bigger sizes of up to 4 metres in width and 3 metres in length.
What sizes can I have my new roof light in?
Maximum sizes are up to 1400mm in width and 6 metres in length.
What sizes can I have my new roof lantern in?
Maximum sizes are up to 4 metres in width and 3 metres in length for regular roof lanterns.
Maximum sizes are up to 1500mm in width and 3 metres in length for contemporary roof lanterns.
Why do you recommend an 80mm kerb width when ordering roof products?
This size best suits our lantern profile, which has an internal groove just the right size for your plasterboard to be fitted and run flush, leaving a clean and professional internal finish.
What are tie bars and when are they required?
A tie bar is an internal T-shaped bar that may be required when a roof exceeds a certain size. You may have seen these before on large conservatory roofs, and they essentially tie the rafters together and further support the roof structure, preventing excess load or collapse.
Our software can calculate when tie bars are required, here are the general rules for our roof lanterns based on size:
Up to 2.5 metres wide - no tie bars required
Up to 3.8 metres - hidden tie bar
Up to 5 metres (depending on design) - rafter tie bar
Will I be given a technical drawing once I place my order?
Any order for a roof lantern will receive a technical CAD drawing for your sign off and approval. This is not usually required on a roof light.
Are the roof pitches fixed?
Roof lanterns come as standard with a 25-degree pitch, and roof lights are recommended to be fit on a 5-degree pitch. We can alter this depending on your requirements but recommend these pitches.
Do you offer roof vents within the roof lantern?
Yes, we can offer roof vents that are either manual opening with a pole or electronic with a remote control or wall-mounted switch.
How do I choose between roof lights or a roof lantern?
Firstly, both options will give you an abundance of natural light! Here are some key points and considerations which should help you decide which is the best fit for you:
Rooflights are well suited to projects that dont want to add any extra height to a building.
Lanterns are seen as more of a feature and will likely be the central focus of the room. Roof lights offer a more subtle, understated look but still offer lots of natural light.
Rooflights are cheaper than lanterns, but often you will require more than one so the cost does even out. For example, on a standard 6m x 3m rear extension you would choose between either a central roof lantern or 2/3 roof lights, depending on your design preference.
Both products are fairly easy to install, roof lights in particular as they arrive pre-glazed for easy installation. Roof lanterns will come with the glass units separate to fit on site.
Consider the look of the products from the upper floor of the house. Do some of the bedroom windows face directly onto the roof? If so decide which product you would rather look at every day - the subtle roof light squares or the more grandiose lantern. Only you can answer this question!
Roof lights do not open, but if you do need some kind of ventilation in your roof product a lantern may be more suitable as we can offer roof vents for these.
Is a roof light the same as a skylight?
Basically yes, a skylight is the American term and some people do refer to a roof light as a skylight. Our product is referred to as a flat roof light, as it is non-opening and sits at a slight pitch.
What are the benefits of your roof products?
The Atlas roof lantern is considered the strongest on the market and is the perfect compliment to a new extension or refurbished room. The ultra-low sight-lines make it much more attractive than competitors roof lanterns!
The roof bars are also slimmer than normal at only 40mm. This gives a more contemporary look with more visible glass area, in comparison to most other lanterns on the market that have a much bulkier appearance.
Of course, the main benefit of any roof lantern or flat roof-light is the expanse of natural light you will get into the home. There is no better way to create a feeling of light and space than by installing a glazed roof product, which is why they are now almost standard on single-storey rear extensions. If you are adding an extension to your home and looking to create a more open plan, expansive feel, then a roof lantern or roof lights are highly recommended.

Bespoke designs to help you capture the mood, whatever space you want to fill.
Consider the intended purpose of the room, when it will be used and who will use it when determining the vision for a Korniche roof lantern. The versatility and customisable colour range ensure that no compromiser is necessary for the perfect fit
Korniche: Powder coating
Boasting a thick, consistently smooth finish that far surpasses a standard coasting, the exterior of the this lantern has been powder coated in a range of attractive colours. Additionally, powder coating creates a remarkably sturdy finish and is more environmentally friendly than traditional methods.
Korniche: Self-clean glass
Installing this powder-coated, glazed lantern grants you full protection from the elements, with a unique self-cleaning glass to reduce your upkeep. Our special transparent coating, harnesses the power of the sun's ultraviolet rays to break down any dirt on the surface of the glass. Subsequently, rain helps to wash away and remnants, enabling you to perform regular cleanings far less often than with conventional glass. This coating is built directly into the external side of the glass. However, it is is still necessary to follow the glass manufacturer's cleaning guidelines at certain intervals.
Korniche: RAL
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.
