What Materials are Best for HVAC Ducts?

Ducts are an essential part of any HVAC system, and the material used to construct them can have a major effect on their performance. From rubber and stainless steel to polyurethane and neoprene-coated polyester fabric, there are a variety of materials used in the construction of HVAC ducts. The most suitable flexible air filter ducts for commercial buildings in extreme climates are usually made from silicone, PVC, rubber, and stainless steel. Wood fiber ducts are created by combining resin with inorganic glass fibers, which act as an air barrier and water vapor retarder to prevent stale air from entering the air stream.

Flexible ducting is the most popular type of ducting due to its ease of installation and affordability. This is why it is so widely used in homes. Flexible ducts are usually made from spring steel wire, propeller plastic, and polymer plastic. Galvanized steel is the most common material used in the manufacture of ducts.

Steel ducts expand and contract as they heat and cool, while aluminum ducts are often used in cleanroom installations and special exhaust systems. Plastic ducting is one of the most efficient HVAC ducting structures available today. On the other hand, fiber air ducts tend to have a shorter lifespan than other types of materials, depending on where you live and how you use them.
