The FAKRO range of domed and non-domed flat roof windows are available in a wide range of sizes and easily fitted to the roof structure as they come complete with an insulated kerb upstand. Therefore there is no requirement for an “on-site” upstand to be constructed. Simply form the opening in the roof structure and install the window. (full detailed instructions are provided with every window) Should you happen to be fitting to a “green or sedum” roof we have available an upstand extension kerb (XRD) that works in the same manner.
