This block combination flashing has been designed for use where four 78 x 118cm FAKRO roof windows are being installed as a block, in a 2 by 2 pattern on tiled roofs. This flashing is designed for profiled interlocking tiles including Marley Ashmore, Marley Double Roman, Marley Ludlow, Redland Landmark and Redland Saxon tiles, and Forticrete Hardrow and Minislate. The 4 block flashing has been manufactured from aluminium as standard, with sections of the flashing being made in a ridged profile for improved malleability around the roof tiles. The flashing is then covered in a polyester coating which improves durability and lifespan, before being finished in a brown grey shade (RAL 7022), which tends to blend in well with most roof tiles. Why do you need FAKRO 4 block combination 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 tiles, ensuring that the window is fitted accurately, creating a neat finish. The 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 tiled 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.
