How To Find Your VELUX Window Size & Code

Identify the size code of your VELUX roof window

Every VELUX window has its own personalized type sign which consists of codes telling you what window you have. This can help when choosing to add a blind, accessory or when replacing your glazing as it tells you exactly what window you have. We designed the VELUX code table below to ensure that you'll never order the wrong accessory.

How to Locate Your VELUX Window's Data Plate

All VELUX roof windows made after 1968 have a data plate (or type sign) giving exact information about the model. You'll find it in the right corner of the top sash, behind the ventilation flap.

The video below will help you locate your data plate.
