Humans generally view doors as a panel that opens access into buildings, rooms, or vehicles, making egress and ingress management easier to handle. Usually crafted from hard, semi-permeable, and resilient materials (like wood or metal), door designs may sometimes involve inserting frames that hold windows or screens in place. Doors are often attached via hinges to their frames for smoother functionality. With a simple motion (angled movement away from the frame, sliding along parallel planes, folding in synchronized angles on perpendicular planes, or rotating around an axis at the center of the frame), doors can control access flow into and out of a building, room, or vehicle effectively. Generally speaking, a door's inner appearance mirrors its outer aspect, but specific designs may present distinct differences between interior and exterior (as seen with vehicle doors). Doors often have locking mechanisms to regulate access levels among people, preventing unauthorised entry attempts. Commonly attached devices on doors help announce an individual's presence outside by installing features like knockers or doorbells. By serving as portals in/out of a given space, doors can play several supporting roles – safeguarding privacy by deterring unwanted attention, demarcating functional zones with different purposes, facilitating natural light passage and exit through exterior apertures to balance temperatures within a controlled environment more effectively by adjusting airflow. Doors also have dampening properties which counteract unwanted external noises, while simultaneously obstructing fire from spreading further in buildings and rooms
