Who are Fakro?

FAKRO windows are renowned for their innovative features and exceptional build-quality. Founded in 1991, FAKRO’s commitment to beautiful design and expert manufacturing has allowed them to grow exponentially, with around 15% of current global market share. FAKRO windows truly elevate any living space, allowing plenty of ventilation and natural light below. What’s more, never resting on their laurels, FAKRO are continually striving to improve their product range.

Whether you’re replacing an existing FAKRO roof window or you’re installing a new window for the very first time, it’s important to find the right size. Thankfully, FAKRO offer an extensive range of windows in a broad selection of sizes, so you’re sure to find the perfect window for you.

To give you a helping hand, we’ve written this handy guide to FAKRO window sizes below.

How Are FAKRO Windows Measured?

Before you come to choose your new FAKRO roof window, it’s important to know exactly what the measurements mean! Ordinarily, the measurements you’ll find below refer to the external frame, and not the glazed area. This measurement is intended to help you when you come to fit the window. So this should be roughly the area you’ll need to cut out of your roof deck, but this can vary if using a flashing kit or insulation collar.

How Do I Find My FAKRO Window Code?

Every FAKRO window, regardless of model, has a unique identifying code. This handy code is consistent across the entire FAKRO roof window range and will help you ensure you choose the right one. You can find the code by looking at the top right-hand corner of the window sash, where it will be marked out. Here you’ll see a handful of numbers and letters.

The first sequence in the top-left refers to the window’s model. To the right you’ll see the dimensions in centimetres, laid out width by height. For example, if the code reads 134/98, then your window’s width will be 134cm and the height will be 98cm.

Finally, below these two codes will be the production code. This will not be necessary in most situations, but it is certainly helpful to know when it is should you need it!
