What type of material is typically used to construct ducts?

Ducts are primarily designed to transport air and other gases efficiently, making materials that are both lightweight and durable essential. The most common material used in duct construction is sheet metal, which includes materials such as galvanized steel or aluminum. These materials are favored because they can withstand changes in temperature and pressure without deforming, maintaining the efficiency of the air distribution system.

In addition to sheet metal, ducts can be constructed from other suitable materials that allow for proper airflow and insulation. This ensures that they remain effective in both heating and cooling applications. The appropriate choice reflects an understanding of the specific needs of the HVAC systems where ducts are utilized.

While wood, glass, concrete, plastic, fiberglass, and various forms of insulation might have applications in other contexts, they do not provide the balance of structural integrity, ease of installation, and thermal efficiency that sheet metal or similar materials offer for ductwork. This understanding of material properties and their implications for airflow is crucial in utility marketing and HVAC system design.
