ductways

Ductways are enclosed channels designed for the transportation of air or other gases. They are commonly used in buildings for ventilation, heating, and air conditioning (HVAC) systems. These systems move conditioned air from a central source, such as a furnace or air conditioner, to various rooms or zones within a structure and then return it to the source for reconditioning. The design and material of ductways are critical for efficient air distribution, noise reduction, and maintaining indoor air quality.

Materials used for ductways vary widely, including sheet metal (galvanized steel, aluminum), fiberglass duct board, and flexible ducting. Each material has advantages and disadvantages concerning cost, insulation properties, durability, and ease of installation. Sheet metal is durable and smooth, reducing airflow resistance, but can be a thermal conductor and is more rigid. Fiberglass duct board offers good insulation and sound absorption but can be susceptible to damage and moisture. Flexible ducting is easy to install in tight spaces but can have higher airflow resistance and is less durable.

Proper sealing and insulation of ductways are essential to prevent air leakage, which can lead to significant energy loss and reduced system performance. Leaky ducts can also draw in unconditioned or contaminated air from attics, crawl spaces, or basements, negatively impacting indoor air quality. Regular inspection and maintenance of ductways are recommended to ensure optimal operation of HVAC systems and a healthy indoor environment. Beyond HVAC, specialized ductways can be used for industrial applications, such as conveying materials or exhaust gases.
