Did you know, ...

... that a „door leaf“ is sometimes called the „door“?

Door set consists of door leaf, door frame, casing, hinges, lock, handle and other completing elements (cornices, imposts, etc.). So the door leaf is only a component of a door set.

... that the „frame“ is actually a „door frame“?

The door frame is installed into a rough opening and attached to the wall by dowel screws (nails hammered into the masonry). Door leaf is attached to door frame by hinges. Casing attached to the door frame conceals the gap between the door frame and the rough opening and helps to hold the frame in the opening. The combination of the door frame, door leaf and other completing elements create a door set.

... that not everything that looks like wood is actually wood?

There is a difference between real solid wood and wood effect finishes. The latter just imitate the appearance of wood, paint and other finishes, using veneer, laminated paper. This provides a surface with an artificial and repetitive texture (wood figure).

... that even the casing and door frames can incorporate elegant design details?

Until recently, almost all the door casings were square and round edges. By the way nowadays profiled designs, decorative matching and embellishing home interior casing is becoming increasingly popular. The rounded edge door frame style is particularly popular, since they provide a more gentle transition between the door frame and the surface of the wall.
