A sliding door is a type of door which opens horizontally by sliding, usually parallel to a wall. Sliding doors can be mounted either on top of a track below or be suspended from a track above and some types 'disappear' in a wall when slid open.[1] There are several types of sliding doors such as pocket doors, Arcadia doors, and bypass doors. Sliding doors are commonly used as shower doors, glass doors, screen doors, wardrobe doors or in vans. This is presentation regarding to the sliding door related to architecture study and their manufacture and types. Types of sliding door on the basis of use and construction. There are mainly three types of sliding door used in residential buildings: 1. Top Hung 2. Bottom Railing 3. Lift and Slide There are also information about the classification of sliding door: 1. Bypass Sliding 2. Surface Sliding 3.Pocket Sliding 4. Bifold Sliding This is presentation is quite enough for the details about the sliding door, and their types.

2. Sliding Doors
A SLIDING DOOR IS A TYPE OF DOOR WHICH OPENS HORIZONTALLY BY
SLIDING,WHEREBY THE DOOR IS EITHER MOUNTED ON OR SUSPENDED FROM A
TRACK.

3. History
SLIDING DOOR WERE USED AS EARLY
AS THE FIRST CENTURY CE IN ROMAN
HOUSES AS EVIDENCE BY
ARCHAEOLOGICAL FINDS IN POMPELI,
ITALY.
IN HISTORY OF SLIDING DOOR IT MAY
HAVE CAME FROM THE ROMAN AND
EUROPEIN COUNTRIES IN KERALA
BOUNDRY GATE HAD SLIDING
MECHANISM.

4. Sliding Door
Gears
THE MECHANISM USED TO OPERATE A
SLIDING DOOR IS CALLED DOOR GEAR.

5. Top Hung
The 'top hung' system is most often used. The door is hung by
two trolley hangers at the top of the door running in a concealed
track; all the weight is taken by the hangers, making the door
easier to move.
At each end is a track stopper to absorb any impact made if the
door is slammed and to hold the door in the open or closed
position.
As the door is hung at the top from two points, it also needs a
bottom track/stay roller to prevent it from swinging sideways.

6.  The most common type is called 'clear threshold guiding', a floor-fixed plastic
guide about 60mm wide which is fixed below the door at the midpoint of its
run. A groove is cut into the bottom of the door which runs over this guide,
preventing lateral movement of the door. With a glass door the panel runs
through the guide as illustrated. Because the door is always engaged in the
guide, when the door is open the floor is clear, hence 'clear threshold'.

7. Bottom Railing
Sometimes a top hung system cannot be used, as the
weight of the door cannot be supported from above; in
this case a bottom rolling system is recommended.
A bottom rolling system consists of two rollers
(sometimes called a sheave) at the bottom of the door
running on a track and two guides at the top running in a
guide channel. As all the weight of the door is
concentrated on the two bottom wheels, more force is
needed to move the door than on a top hung system.;

8. Lift-and-slide door gear
A sliding door that is lifted from the frame during opening and closing is called a lift-and-slide door.
This allows for a better seal, with less draught and better sound proving.

9. Types of Sliding Door
BYPASS SLIDING
SURFACE SLIDING
POCKET SLIDING
BIFOLD DOORS

10. Bypass Sliding
• Doors Slide on overhead track and along guides or track on the
floor .
• Requires no operating space but is difficult to seal against
weather and sound.
• Offers access only through 50% of doorway width .
• Used on exterior as sliding glass door.
• Used in interiors primarily for visual screening.

11. Surface Sliding
SIMILAR TO A BYPASS SLIDING DOOR BUT PROVIDE
ACCESS THROUGH FULL WITH OF DOORWAY.
NO OPERATING SPACE REQUIRED BUT IS DIFFICULT
TO WEATHERPROOF.
DOOR IS SURFACE-HUNG ON AN EXPOSED
OVERHEAD TRACK.

12. Pocket Sliding
DOOR SLIDES ON AN OVERHEADTRACK INTO AND
OUT OF A RECESS WITH IN THE WIDTH OF A WALL.
DOORWAY HAS FINISHED APPEARANCE WHEN FULLY
OPEN .
USED OFTEN WHERE A NORMAL DOOR SWING
WOULD INTER FACE WITH THE USE OF A SPACE.

13. Bifold Sliding
HINGED DOOR PANELS FOLD FLAT AGAINST ONE
ANOTHER WHEN OPENED .
BIFOLD DOORS DIVIDE INTO TWO PARTS, REQUIRE
LITTLE OPERATING SPACE , AND ARE USED PRIMARILY
AS A VISUAL SCREEN TO ENCLOSE CLOSET AND
STORAGE SPACES.
ACCORDION DOORS ARE MULTILEAFED DOORS THAT
ARE USED PRIMARILY TO SUBDIVIDE INTERIOR SPACES .

14. Conclusion
SLIDING DOOR ARE EASY TO USE AND HANDEL
SLIDING DOOR ARE EASY TO INSTALL
SLIDING DOOR CAN BE USE FOR SMALL AS WELL AS LARGE SPAN OPENING
IT IS COSTLY TO INSTALL THIS DOORS THAN NORMAL PANEL DOOR
NORMAL SLIDING DOOR OCCUPY HALF THE AREA OF OPENING BUT IN THIS CASE POCKET, SURFACE
AND BIFOLD DOORS CAN BE USE
