What is draught definition?

Draught (also spelled "draft" in American English) refers to the flow of air through a room or building, which is created by the movement of air from areas of high pressure to areas of low pressure. This can occur naturally due to temperature differences between indoor and outdoor environments, or it can be created artificially through the use of fans, vents, or other mechanical systems.

Draughts can be beneficial in some circumstances, such as in commercial or industrial settings where they are used to control airborne contaminants, regulate humidity levels, or provide ventilation for machinery. However, in residential or office settings, excessive draughts can be uncomfortable and can lead to energy waste as heated or cooled air is lost to the outside.

There are various methods for reducing draughts in homes and buildings, such as sealing gaps around doors and windows, installing weatherstripping, or adding insulation to walls and ceilings. By reducing air leakage and controlling the flow of air through a building, occupants can improve energy efficiency, indoor comfort, and overall air quality.
