Types of Doors

10/8/2012 12:55:14 PM | by Anonymous


Doors are present almost everywhere and in every type of structure. A door allows a person to have an access to an inside space within a building or other type of structure. The role of a door is not only to authorize entry, but also act as a safety barrier which can be locked to prevent unwanted or unauthorized access to the inside space. All doors are movable structures and can make use of a panel which swings on hinges or a panel that spins or slides inside a space. These orientations allow the door to open and close, allowing admission into the structure. Open doors can serve as ventilation, admittance to people or animals as well as light. The physical atmosphere within a space can be controlled by closing or opening the door. For example, a room can be cooled using an air conditioner and the door can be closed to keep the cool air inside. Doors can even prevent fire from spreading from one area to another if they are coated with certain chemicals or if they are made of certain fire-retardant materials.


The functions of doors are countless and these features contribute to a structure in several ways. From adding to the aesthetic appearance of the structure, keeping noise out, limiting unwanted access, keeping formal and utility areas separate and acting as a safety barrier, doors are primarily used for privacy, convenience, security and safety reasons. With the advancements in technology, there are doors today that can keep one safe from explosions. These doors, commonly known as blast-proof doors, do not succumb to the pressure of explosions on the outside and keep the occupants safe. Doors for home use come in a variety of designs to compliment the style of the home. Many home designers tend to choose the type of door that would be used in a home, in order to compliment its décor and style.


Hinged Doors

One of the most common types of doors used in homes, offices and other structures, hinged doors are what people generally tend to think of when the word door is mentioned. These types of doors can be found everywhere and their simple installation process and operations make these doors so popular. A simple block of material, usually wood or plastic, is hinged to a space. The door usually has a handle to allow a person to pull or push the door open, as well as allowing the door to be locked in a fixed position. Taller doors would require more hinges to be able to function properly without collapsing. Commonly used on front, rear or wardrobe doors, hinged doors offer several advantages, of which some are inexpensive and low maintenance cost, can be easily customized and very common in the market. However, one disadvantage may be that such doors require some swing room for them to open and close.


Sliding Doors

Also one of the most common variation, sliding doors can be found usually at supermarkets, stores and even washrooms. These doors are typically used when there is a limitation over the amount of space available, and hinged doors would not be ideal. They consist of a fixed panel that is attached to two hangers on rollers that slide along a track. The sliding movement of the panel back and forth creates a door opening. There can be several variations to the designs of sliding doors, depending on several factors such as necessity, space available and the taste of the customer. One common variation of such doors is the pocket door. It has the design of a regular sliding door, but slides back into a recess in the wall which completely conceals it from view when the door is in its open position.
