Product Description
How to Measure
Step 1 – External Kerb
The key measurement to take is the external kerb size, as shown in the diagram above. When measuring the base (or kerb) where the lantern will be installed, you need to record the outside dimensions — both the length and the width.
Step 2 – Important Note
The kerb is usually constructed from timber, with an ideal width of 80mm. Please note that the minimum allowable kerb width is 67mm.
Flat Glass Rooflight FAQ's
Please read our FAQs page to find out more.
What is ‘self clean’ glass?
Self cleaning glass combines both self cleaning and solar control properties, making them highly desirable amongst homeowners looking for the ultimate in glass solutions. The coating that is applied to the glass breaks down organic dirt and by doing so reduces the adhesion of inorganic dirt. Water droplets are spread out to form a sheet and this picks up the loosened dirt particles as it drains off the surface. The result is remarkable and a difference you can actually see.
What does U Value mean?
Thermal transmittance, also known as U-value, is the rate of transfer of heat through the glass. It is measured as watts per square meter Kelvin or W/m²K. The better the insulation, the lower the U-value is.
Why does aluminium need to be thermally broken?
Aluminium like all metals is a conductor of heat. If our profiles weren’t thermally broken the inside heat would be wicked away and lost to the colder outside. By creating a profile assembled with polyamide sections between the inside and outside portions, the ‘thermal bridge’ is stopped. Polyamide is a glass filled plastic meaning it is an insulator and therefore there is virtually no conduction of heat through it.
Why is PAS24:2016 important?
Thermal efficiency of the Korniche has been guaranteed by the elimination of cold bridging, this is achieved by the total isolation of the external aluminium profiles from the internal ones. Combined with high performance glazing, the Korniche’s ability to reduce heat transfer is in a class of its own.
What glazing do you recommend?
We offer different glazing tints, all detailed on the ‘Korniche Roof Lantern’ section of our website. 1.2 U-value glazing is the equivalent to double glazing, and can be supplied in Clear or Blue. Our 1.0 U-value glazing is the equivalent to triple glazing, and reflects 85% of the solar glare. This can be supplied in Clear orAqua.
