FAKRO windows are growing in popularity, due to their focus on sustainability, practicality and style.

Pitched roof windows from FAKRO are the perfect way to bring extra natural light into your home, helping to minimise energy bills, create a healthier home, and provide ventilation. FAKRO windows are also popular due to their range of glazing types, window opening types, and window sizes.

But which FAKRO window size do you need?

We’ve created a quick guide to FAKRO window sizes to take you straight to the windows you require.

Why are FAKRO window sizes important?

FAKRO window sizes matter for a number of different reasons. This could be because of daylight requirements in the property or down to simple roof pitch restrictions which can affect the size of the window you choose.

When it comes to daylight, a higher roof window can provide a great deal of light into the room. Many roof windows can luckily be fitted to a roof pitch between 15° and 90°, but this can differ depending on the type of window. So this will affect the choice you make when choosing a roof window.

It’s also worth noting that the lower the roof pitch, the higher up the roof window will need to be. So ensure you know whether you want a small or large window when moving forward with a low-pitch roof.

With that in mind, let’s check out the different FAKRO window sizes you can choose from!
