Flashings are essential for tight connection of roof windows with roofing material. Precisely designed flashing details ensure a durable and neat fit with the roofing material used. The purpose of flashing is to ensure good drainage away from the window and to provide protection from the wind.
Flashings can be used with all types of the centre-pivot windows (FT, PT), with raised axis of rotation (FYP, FDY), the top-hung windows (FPP, PPP, FEP), as well as windows for combinations (FX_, FT_/D, B__).(FT_/D, B__).
These types of windows can be combined in various combinations. Thanks to the uniform design of flashing, different types of windows can be com-bined into groups. FAKRO offers a range of flashing solutions, manufactured in polyester powder coated aluminium to give high durabilty and resistance to atmospheric conditions. The standard colour is brown RAL 7022, which matches well with most roofing finishes.
Roof windows can be installed in the roof structure at three different levels: N (3cm), V (0cm) and J (-3cm). Flashings are categorised accordingly.
The third letter of the flashing type code indicates the depth at which the roof window can be fitted. Flashings symbol have been extended to the fourth letter that indicates the type of material the apron is made of: P- lead apron, A- aluminum clad - plastic apron.
