Door :-A door may be defined as a framework of wood, steel, aluminium, glass or

combination of these materials secured in an opening left in a wall for the purposes

of providing access to the users of the structures.

It basically consists of two parts i.e. 1) A frame and 2) shutter (leaf)

Functions:-• Very important as respect to planning process.

• Helps in ventilation and admit light in the structure.

• Provide privacy of sound and sight.

• They also provides safety. Etc.

1. From consideration of adequate air circulation within the room, the doors should

be provided on opposite walls facing each other.

2. From consideration of proper space utilisation and privacy, doors should as far as

possible be located near the corner of a room (say about 20cm away from the

corner).

3. The location of the door should meet the functional requirements of the room.

4. The number of doors in a room should be kept minimum to achieve optimum

utilisation of space. Large number of doors besides causing obstruction, consume

more area in circulation.

• These doors are extensively used for shops, garages, public buildings,

godowns etc. and in situations where width of opening is large and

provision of hinged shutter becomes difficult for want of space.

• These doors are also used from the considerations of safety and protection

of the property.

• These doors are commonly recommended in situations where light and

ventilation are desired even when the opening is closed.

• These doors are commonly used for show windows, stores, shop fronts and

godowns etc. The door shutter acts like a steel curtain and provides

adequate protection and safety against burglars and fire.

• The shutter consist of thin steel slabs about 1.25mm thick interlocked to

each other and coiled upon the specially designed pipe shaft. When the

area of door opening is more than 10sq. m. the shutter is generally opened

or closed by means of chain pulley blocks.

rolling steel door in all respects except the type of shutter. The rolling grill

choice.

visibility and ventilation is also desired. It also used in places like

transformer rooms, substations etc.

• Fire check doors are required to control and restrict the spread of fire

through the door openings thereby minimising the damage of the adjoining

property in the event of fire.

• By provision of fire check doors it is possible to prevent the spread of fire to

communicating rooms and floors i.e. the chimney effect.
