Korniche Flat Glass and FlatLite: What Is the Difference?

Korniche flat glass and Korniche FlatLite are separate rooflight systems. Similar names do not mean their sizes, glass options or installation details can be used interchangeably.

Identify the system you are buying

Our Korniche Flat Skylight designer is for the framed flat glass product. FlatLite has its own online designer. Use the correct designer for the product you intend to buy, and write the full name on the specification and drawings so everyone is working with the same system.

Compare options on the actual quote

Compare the glass build-up, finish, dimensions and kit inclusions for the exact product being quoted. The FlatLite designer offers its available set sizes and glazing choices. Use its stated external-upstand measurement reference, including the waterproof membrane, and follow the current product drawing. Do not enter FlatLite dimensions into the framed-product designer or assume the two systems use identical support details.

Use the right installation PDF

Download the installation document for the selected system before the kerb is built. Compare the required measurement reference, support and waterproofing detail with the proposed roof construction. If two drawings disagree, ask which applies to your unit instead of choosing the more convenient dimension.

Think beyond the initial appearance

Consider the internal ceiling junction, cleaning access and future service work. Ask how the chosen system’s glazing is maintained or replaced and keep the applicable care instructions. At handover, retain the full product name, order reference, dimensions, finish and glass specification so future enquiries can be answered accurately.
