The Korniche Flat Rooflight is a premium solution for flat and low-pitch roofs, offering a sleek, frameless appearance combined with excellent thermal performance. Designed with installer efficiency and homeowner appeal in mind, it provides a contemporary alternative to traditional dome rooflights. Whether you are installing the product or simply want to understand the process, this guide outlines each stage of a typical Korniche Flat Rooflight installation clearly and accurately.
Understanding the Korniche Flat Rooflight System
Korniche Flat Rooflights are manufactured using a thermally broken aluminium frame paired with high-performance, double-glazed safety glass. The minimalist external design allows the glass to sit flush with the roof surface, creating a modern, architectural finish.
The system is designed to be installed onto a builder’s upstand or kerb and is supplied fully assembled, reducing installation time on site. View the Korniche Flat Rooflight range.
