A genuine security improvement should make unauthorized entry more difficult, provide a reliable warning, or both. A thin layer of foil doesn’t substantially strengthen the door, lock, strike plate, frame, or hinges.
So while the foil may look unusual, its appearance shouldn’t be mistaken for protection.
