Air ducting refers to a system of pipes or channels that are used to circulate air throughout a building or other enclosed space. The ducts are typically made of sheet metal or flexible material, and can be used to transport heated or cooled air from a central heating or air conditioning system to various rooms or areas within a building. The ducts are usually concealed within walls, floors, or ceilings, and are designed to provide a consistent flow of air to maintain a comfortable temperature and improve indoor air quality. Properly designed and maintained air ducting systems are important for energy efficiency, comfort, and health.
