Different types of doors are used in homes and buildings. Doors are the most important assets in any home, not just for security.
However, they also improve the appearance of the house from the outside. The type of door chosen depends on the type of structure, house, and purpose of use.

What is Door?
A door is described as a moveable structure used to open and close an entry or to provide access in or out of something.

There are several door styles to choose from to make your home’s entrance more appealing.

An a-frame is used to give excess, indoors or outdoors, as to a structure or room, or to allow access to a closet, cabinet, etc.: Most doors pivot on hinges, slide in grooves, or revolve on an axis.

TYPES OF DOORS

There are several types of doors in use, which may be classified based on the arrangement of shutters, construction methods, functioning principles, and materials utilized. The following are some of the most commonly used doors:

1. BATTENED AND LEDGED DOORS
Battens are wooden boards that are 100 mm to 150 mm wide and 20 mm thick. Their length corresponds to the width of the doorway. The battens are joined together by horizontal boards called ledges that are 100 to 200 mm wide and 30 mm thick. Typically, three ledges are used: one at the top, one at the bottom, and one at mid-height. This is the simplest and cheapest type of door. Battens are joined together by a tongued and grooved joint.

2. BATTENED, LEDGED AND BRACED DOORS
If the doors are spaced too far apart, diagonal components called braces are used to strengthen the door.

3. FRAMED AND PANELLED DOORS
This door is made up of vertical styles and horizontal rails. The posts and rails are grooved to support panels. The panels might be made of wood, A.C. sheets, glass, and so forth. To provide a pleasing look, the panels may be flat or elevated. These are often used for doors. They might have single or double shutters. Glazed doors are those that have glass panels.

4. FLUSH DOORS
These doors’ shutters are constructed of plywood or block boards. They are all the same thickness. These shutters are available in a variety of appealing vineer finishes. Making such doors on-site takes very little time. These doors are appropriate for the interior of a structure. Flush doors are now extensively used in residential and commercial structures.

5. LOUVERED DOORS
Such doors can be used when both privacy and ventilation are necessary. Louvers can be made of glass, wood, or air conditioning. Sheet strips are inserted into the shutter frame to prevent vision while allowing free air flow. The doors can be louvered entirely or partly. These types of doors are typically found in public restrooms and latrines.

6. REVOLVING DOORS
It is made up of a pivot in the centre, to which four radiating shutters are linked. The central pivot is supported at both ends by ball bearings and bush bearings. The shutters might be partly or entirely constructed of glass. Shutters revolve within a circular entry area. The rotation of the shutters allows admission on one side and escape on the other. These doors are recommended in public establishments such as supermarkets, banks, hotels, and theatres where doors must be used on a regular basis. They are absolutely necessary at the entrance of air-conditioned public facilities.

7. SWING DOORS
Swing doors use double-action springs to attach the shutter to the frame. As a result, the shutter may be moved both inward and outward. They can have a single or double shutter. Offices and banks favour such doors. Because these doors may be opened on both sides, it is preferable to have glass panels or peep holes that let the user view the people on the other side.

8. SLIDING DOORS
Side-sliding shutters are used in this sort of door. Runners and guide rails have been installed for this purpose. There might be one, two, or even three sliding shutters. Such doors can be found in banks, workplaces, and other public places.

9. COLLAPSIBLE DOORS
Verticals are made of steel channels 16 to 20 mm wide. They are separated by 12 to 20 mm. They are hinged with steel flats 16 mm to 20 mm wide and 5 mm thick. The rollers are provided at both the top and bottom of the shutter, allowing it to be pulled or pushed sideways with minimal force. Single or double shutters are possible. These doors are typically used for further security. Front doors, bank locker rooms, and school and college entry doors are all typical uses for them.

10. ROLLING DOORS
It is made up of a thin steel plate frame, a drum, and a shutter. The width of the door can range between 2 and 3 metres. The shutter rolls up and down on steel guides placed on the sides. Helical springs on the drum are used for counterbalancing. The shutter may be simply lowered. From a safety standpoint, this type of door is widely used as an extra door for businesses, offices, banks, factories, and buildings.
