Korniche Flat Glass and FlatLite Surveying Guides

Planning a flat rooflight? These guides show how to measure up for a Korniche Flat Glass or FlatLite rooflight. They cover the size and slight slope your upstand needs so rainwater runs off, how high it should sit above the roof, and how to check the opening is square. Both rooflights can be made up to 3m² in size.
