This B2/1 horizontal twin flashing has been manufactured for the installation of two standard 55 x 98cm FAKRO roof windows side by side on a slate roof.
The FAKRO horizontal twin flashing is manufactured specifically for use on roofs where the tiles are less than 10mm thick, particularly natural slate and fibre cement slate products.
The flashing has been manufactured from aluminium as standard, and parts of the flashing are ridged to allow for malleability around the slate and roof windows. The flashing is then coated in a polyester varnish which adds protection and increases durability. The flashing is a brown grey shade (RAL 7022) which is the standard colour of FAKRO flashings, due to its ability to blend in with a wide range of roof coverings.
Why do you need FAKRO horizontal 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 windows 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.
