Write a short note on doors and its types.
A door is a movable barrier fixed in a wall opening for entry, exit, privacy, security and weather protection. It has a frame and a shutter.
Types by construction
- Battened and ledged door: vertical boards held by horizontal ledges; cheap, for stores and sheds.
- Battened, ledged and braced door: diagonal braces added to stop sagging.
- Framed and panelled door: stiles, rails and panels of wood, plywood or glass; the usual door for houses and offices.
- Flush door: flat faces of plywood over a timber frame; plain and modern.
- Glazed door: panels of glass for light and view.
- Louvred door: fixed or movable slats for ventilation (bathrooms).
Types by working
- Sliding door: moves on tracks, saves space.
- Folding door: hinged leaves fold together.
- Revolving door: turns on a central pivot, used in hotels and banks.
- Swing (double-acting) door: opens both ways, used in hospitals and kitchens.
- Rolling shutter: steel slats rolled on a drum, used in shops.
Doors may be of timber, steel, aluminium, UPVC or glass. Timber must be well seasoned, free from defects and preferably treated (sal, teak, sisau, uttis in Nepal).
