Measuring Guide
On all VELUX roof windows you will find a type sign stating exact information about the window. For instance as regards the roof windows with control bar (illustrated below) the data plate is placed in the right corner of the top sash behind the ventilation flap. On other types of VELUX windows you will find the type sign somewhere visible on the inside of the frame or sash or behind the ventilation flap.
All you have to do, when ordering a blind, is to indicate the window code of the data plate to make sure you receive the right product. To find out your window code see below.
