This is a FAKRO flashing, designed for pairs of 78 x 98cm FAKRO roof windows that are installed vertically on a slate roof.
The FAKRO vertical twin flashing has been designed to allow the installation of two FAKRO standard roof windows in a vertical pattern, one on top of the other. The flashing is specifically manufactured for use on slate roofs where the slates are up to 10mm thick, such as natural slates, fibre cement slates and more.
The FAKRO B1/2 vertical twin flashing is manufactured from aluminium, with some sections manufactured with a ridged profile to allow malleability around windows and the slate tiles. The flashing is then covered with a polyester coating to provide durability, before being finished with a brown grey (RAL 7022) shade, which blends in with most roof coatings.
Why do you need FAKRO vertical twin flashings?
Flashings are an integral part of the installation of a FAKRO window, and although often disregarded, are incredibly important.
Flashings are used to create a tight connection between the roof window and the roof slate, ensuring that the window is fitted accurately, creating a neat finish. The twin flashings tend to allow a distance of around 10cm between each window.
However, the FAKRO flashing is not just used for visual effect, the flashing is also used to protect the windows from weather conditions, creating efficient rainwater drainage with the ridged design, and preventing water entry at the points where the windows connect to the roof.
By installing FAKRO flashings on your slate roof, you are eliminating the potential for water to penetrate the roof, which prevents damp, condensation and structural issues from occurring over time. FAKRO flashings also help to increase the lifespan of the roof and the standard roof windows.
