Answers:    Fill contained by the space with a jamb extender, some square shaped pieces of wood may work on the interior cut to the 15mm you are shy. If it is shy on the exterior, I would suggest rehanging the door and finish the initial on the interior.

If the door frame is wood and has some sort of jacket or brick moulding on it, you can cut the 15 mm from the back side of the film to make jamb chain up with interior.

Cut some wood and extend the door jamb.If the brick mold is flush to the outside you will enjoy to buildup the inside.If the door is flush to the inside you will have to extend the jamb for the brick molding.
