A modular installation flashing for interlocking flat tiles

If you have a roof covered with interlocking flat tiles and want to install more than one roof window in it, then RoofLITE+ FCX flashing is the ideal choice for you.

FCX flashing
enables the installation of two or more RoofLITE+ roof windows side by side, with
a 120 mm gap between them. Two flashing variants are available:

  • FCX 13F – allows two windows to be installed side by side
  • FCX 2F – FCX 2F – allows you to install one roof window between two other windows. The FCX 2F flashing can only be installed in combination with the FCX 13F flashing.

It is also possible to install the windows one above the other, but in this case you will need an additional component from the RoofLITE+ UCX set (depending on the installation variant). <<link to UCX 13 flashing>>

The FCX flashing can be used in roof pitches between 15° and 90°.

The FCX flashing ensures an airtight connection between your windows and the roof, regardless of which RoofLITE+ window model you choose. <<link to roof windows category>>. The flashing is manufactured from aluminium that is resistant to all weather conditions and is finished in a colour that matches the RAL7043 (grey) external finish of RoofLITE windows. FCX flashing has a tight-fitting apron that ensures tightness even in heavy rain and strong winds.


The flashing also comes with protective components for the RoofLITE+ window frame.
