How can I find out the accurate size of my roof windows?

Each Fakro roof window comes with a helpful ID plate within the sash of the window on the top right hand side which features a long code. We work using that code because it provides easy product identification and has details of product type, dimensions and production code.

For example, you'll notice the ID plate may say 78/118 or 114/118 - this is the size you will need to look for. On roofwindows4you.co.uk our products can be listed by size so please search for that term.

Sometimes we have queries about the glass measurements and if that's how you know what size to order. Unfortunately, this method is incorrect. Measuring the size of the glass will give you the wrong measurements therefore causing problems for your order as it'll come across as a bespoke size.
