Flues with twin-wall construction refer to a type of chimney or duct that is composed of two layers of metal pipes with an air gap in-between. The inner layer carries smoke or other gases from a furnace, fireplace, or similar appliance while the outer layer provides insulation and prevents heat loss. This type of construction allows for efficient venting and reduces the risk of fire hazards.
