Window Identification

Find Your Window Code

Your VELUX® window code is essential for accurate quotes and compatible parts

How To Find Your Code

1

Open Your Window Fully

Open your VELUX® window as wide as it will go to access the top edge where the identification plate is located.

2

Look For The Metal Plate

On the top edge of your window, you'll find a silver metal data plate. This contains all your window's identification information.

3

Note The Code

Write down the model code (e.g., GGL, GGU) and size code (e.g., MK04, SK06) printed on the plate. This is your window code.
