How to identify your Velux window

There is no need to measure your window to identify the blind size you need when purchasing our blinds. Most window manufacturers have a plate located on the top or side of the window frame that will have a window type and code. See example below:

Window type – GGL

Window code- M04

Once the window type and code are identified, make sure you select the correct option in the list when purchasing.
