Here is a great place to buy windows from. For an example.
As well as other parts.

Keep in mind that the windows and doors must also be EU safety approved even though it does certainly depend upon your inspection officers there in Latvia. Believe me I know from experience.
Ive got a very long list of places and manufacturers to purchase parts from. Here in Finland and across Europe and Scandinavia. Please let me know and I,ll list more for you.
Also check your local caravan dealers because sometimes they have old stock that they want to just get rid of and very reasonable. That includes windows, caravan siding, lighting and the list goes on.
For doors you can easily make your own using 19mm plywood or whatever thickness it is you prefer for a nice looking one.
For moulding or edge trim its the same. Fenders are a bit of a different story however you can always make your own and styles designs are many.
In German the moulding is "Abdeckleiste"
