Which type of duct material is typically recommended for clothes dryer exhaust?

Choosing smooth wall metal, usually galvanized steel, as the recommended duct material for clothes dryer exhaust is based on several key attributes that ensure effective and safe venting. This material is durable and heat-resistant, which is critical since dryer exhaust can reach high temperatures. The smooth wall design minimizes friction and buildup of lint, which is essential for preventing clogs and reducing the risk of fire hazards.

Smooth wall metal ducts also have a smooth interior surface that facilitates proper airflow, allowing for efficient venting of moisture and hot air. This efficiency is crucial in maintaining dryer performance and ensuring that heat is adequately expelled from the dryer. Other options, such as plastic and vinyl, may not withstand the heat generated during dryer operation or may deteriorate over time, creating hazards.

Aluminum foil ducting, while sometimes used, is not as robust or effective for long-term, high-efficiency use as smooth wall metal ducts, which provide a superior solution for dryer exhaust systems. Overall, smooth wall metal ducts combine safety, durability, and performance, making them the industry standard for venting clothes dryers.
