Step 1 โ€“ Open Your VELUX Window

Gently open your roof window so you can access the top edge of the sash (the moving part of the window).

The identification plate is not visible when the window is closed, so you will need to open it slightly to locate it.

Step 2 โ€“ Locate the Identification Plate

Once the window is open, look along the top edge of the sash. Youโ€™ll see a small metal plate or sticker fixed into the frame.

This plate contains important product details, including:

  • Model code
  • Size code
  • Additional manufacturing information

Itโ€™s usually silver, grey, or black with printed text.

Step 3 โ€“ Note Down the Window Code

On the plate, youโ€™ll see a combination of letters and numbers.

For example:

  • GGL MK04
  • GGU CK02
  • GPL FK06

The size code (such as MK04, CK02 or FK06) is the most important part when selecting your blind. Make sure you copy it exactly as shown, including any letters.

Once you have this code, you can confidently choose the correct blind size in our calculator.


If youโ€™re unsure or the label is worn or difficult to read, simply take a clear photo of the plate and contact us. Weโ€™ll be happy to help you confirm the correct window code before you place your order.
