Types of Doors you must know !!

A door is a moving structure used to block off, and allow access to, an entrance to or within an enclosed space, such as a building or vehicle. Similar exterior structures are called gates. Typically doors have an interior side that faces the inside of a space and an exterior side that faces the outside of that space. While in some cases the interior side of a door may match its exterior side, in other cases there are sharp contrasts between the two sides, such as in the case of the vehicle door. Doors normally consist of a panel that swings on hinges or that slides or spins inside of a space.

Panel doors

• Stiles - Vertical boards that run the full height of a door and compose its right and left edges. Thehinges are mounted to the fixed side (known as the "hanging stile"), and the handle, lock, bolt or latch are mounted on the swinging side (known as the "latch stile").
• Rails - Horizontal boards at the top, bottom, and optionally in the middle of a door that join the two stiles and split the door into two or more rows of panels. The "top rail" and "bottom rail" are named for their positions. The bottom rail is also known as "kick rail". A middle rail at the height of the bolt is known as the "lock rail", other middle rails are commonly known as "cross rails".

Plank and batten doors

Plank and batten doors are an older design consisting primarily of vertical slats:

• Planks - Vertical boards that extend the full height of the door, and are placed side by side filling the door's width.
• Battens - Smaller slats that extend horizontally across the door which the planks are affixed to. The battens hold the planks together. 
• Sometimes a long diagonal slat or two are also implemented to prevent the door from skewing. 
• On some doors, especially antique ones, the battens are replaced with iron bars that are often built into the hinges as extensions of the door-side plates.

Moulded doors

• STILES and Rails - As above, but usually smaller. They form the outside edges of the door.
• Core material: Material within the door used simply to fill space, provide rigidity and reduce druminess.

Impact-resistant door

• Impact-resistant doors have rounded stile edges to dissipate energy and minimize edge chipping, scratching and denting. 

• The formed edges are often made of an engineered material .

•  Impact-resistant doors excel in high traffic areas such as hospitals, schools, and hotels.

Flush doors

Many modern doors, including most interior doors, are flush doors:

• Stiles and Rails- As above, but usually smaller. They form the outside edges of the door.
• Core material: Material within the door used simply to fill space, provide rigidity and reduce drumminess.
