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.
