One of the most significant advantages of fiberglass ducts is their ability to resist heat loss and gain. Unlike metal ducts, which can conduct heat easily, fiberglass ducts have low thermal conductivity, allowing them to maintain a constant temperature throughout the system. This feature not only ensures efficient heating and cooling but also reduces energy costs by minimizing the amount of energy required to maintain desired temperatures.
