Chimney construction is the process of building a vertical structure that allows exhaust gases and smoke from a fireplace, stove, or furnace to escape a building. Chimneys are typically constructed of brick, stone, or metal and are designed to withstand high temperatures and the corrosive effects of combustion byproducts.
Chimneys play a vital role in maintaining indoor air quality and preventing fires. They create a draft that helps draw combustion gases up and out of the building, preventing them from accumulating indoors. Chimneys also help to keep the exterior of the building cool by dissipating heat from the fireplace or stove.
