How does a door keep the outside elements from penetrating into the interior?
Actually, the door works in concert with weatherstripping, the door frame, and the threshold to keep the elements at bay. Usually, the door itself has insulating value provided either by its mass, as in a solid door, or by insulating material fabricated into the core of the door by its manufacturer. The weatherstripping, doorframe and threshold prevent air penetration around the door.
