Find Your Window Code

Every roof window carries a code on an ID plate inside the frame. That code tells us the exact size, so your blind is made to fit with no measuring.

Animated example: opening a roof window sash to reveal the ID plate with the window type and size code
Example illustration — plate position and layout vary by brand.

Where is the code?

  1. 1. Open the sash. Swing the window open so you can see the top bar of the opening frame.
  2. 2. Find the ID plate. Look for the metal plate or label on the sash.
  3. 3. Read the code. The window type comes first (for example GGL), then the size code (for example M06).
