Measuring & Installation Guide

The Korniche Roof Lantern is custom made to your exact sizes. This product works with external upstand measurements and recommend a minimum 69mm wide upstand is used. To calculate your required size, measure the length and width from the outside edge of your timber upstand finished with roofing material.

Your external upstand dimensions should be 6mm smaller all around than the size you purchase. If you purchase a 1000mm by 1000mm from our website then your external upstand dimension should be 6mm smaller all around which would make the external upstand dimensions 988mm by 988mm. In other words add 12mm to the length and 12mm to the width over the actual upstand measurements, this is the size you’d need to purchase from us.

The height of the upstand should be 150mm and minimum width should be 69mm.

Glass roof lanterns are often the last piece of the jigsaw on flat roof extensions.

The Korniche roof lantern is engineered to ensure the installation is a quick and easy operation ensuring your home becomes secure and water tight in the minimum time possible.

The Korniche roof lantern is delivered in kit form and leaves the factory with all components checked and quality controlled. Your builder or installer will have a comprehensive installation guide with all dedicated parts required for a speedy installation.

Revolutionary design for rafters and factory fitted cast aluminium bosses link spas and eaves beams with simple but strong one bolt fixings. 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.

The 24mm double glazing units are fitted with the all in one glazing retainer in seconds, clip fit top and end caps ensures the whole glass roof lantern is complete in minutes and not hours.

The glass balustrade gives us an amazing view onto the lake outside. So happy we ended up going for the frameless glass balcony from Toughened Glass Systems instead of one with posts

My job is to design the interiors for a lot of houses and a lot of times the hardest part was when the client wanted some really inexpensive rooflights that should look like some contemporary ones as well. That until I found Toughened Glass Systems and started working with them more and more. They have a lot of this kind of stuff at a very decent price, a price for anyone I can say. If you’re looking for cheap skylights for flat roofs or any types of roof lights, they probably have something for you.
