Where do I find the type and size code
of my roof window?

When you pivot your VELUX roof window open, you will find the data plate containing the type and size code on the top of the rotating sash, on either the left or right side.

The data plates may look different depending on the age (generation) of your roof window. Look at the examples to see which plate corresponds to the one on your window and discover how to read the correct data.

Check the product title. Make sure that the size code mentioned in the product title exactly matches the size code found on your window's data plate.
