Types of Ducting System Design in Spanish Trail, NV; Flexible or Rigid Metal, Fiberglass or Fiberboard Air Ducts

Homes and commercial buildings use air duct systems to direct the conditioned air through the building. There are two major types of air duct systems that vary on the type of materials used. Where neither type of system is considered superior, they each have their own set of benefits and disadvantages. Air Supply Heating & Air Conditioning will break down the basic air duct systems and why they are chosen.

Flexible Air Duct Systems

Flexible air ducts are one of the more common types of air duct systems used and you will find them mostly used in residential homes. Flexible air ducts can do tighter turns and snake through smaller buildings like homes much more efficiently. They are often secured in with hangers and other support systems to prevent the air ducts from sagging or kinking which can restrict the air flow. Flexible air ducts use a tubuar shape that uses a wire coil to hold the air duct structure. The coil wiring is then covered with a bendable plastic material. Flexible air duct systems are more superior inasmuch as they can be installed more easily. However, they are prone to puncturing. Another common problem with flexible air ducts is that rodents can eventually chew their way through the material leading to air duct leaks. However, the materials used are resistant to mold growth and moisture damage such as rusting.

Rigid Air Ducts

Rigid air duct uses about three different types of materials and can be rectangular or circular in shape. Rigid air duct systems are solid and are fitted around the building in small pieces much like hamster tubes. Rigid air ducts are often found in commercial and/or larger buildings and occasionally in residential homes.
Sheet Metal Air Duct Systems: Sheet metal air duct systems often use galvanized steel and aluminum. Aluminum is often favored because it is lighter and smoother than galvanized steel which helps make aluminum more resistant to mold and the collection of condensation which can trigger rust.
Fiberglass Air Ducts: Another type of rigid air ducts are fiberglass lined ductwork. Fiberglass is often used in office buildings as the fiberglass is able the absorb sound which can reduce the noise from the HVAC system as well as echoing voices. However, fiberglass must be replaced when exposed to mold and/or ages. The fibers make it difficult and hazardous to clean. As the fiberglass ages the fibers can also break down and become air born.
Fiberboard Ductwork: Fiberboard air ducts are made from fiberglass strands that are compressed and bonded with a resin compound. The resin is then covered with a foil laminate sheet to protect the surface from moisture. The foil can help repel mold development. The foil also helps to insulate the cooled or heated air which does increase efficiency. However, if the foil is damaged and moisture gets inside the fiberboard, it is a perfect breeding ground for mold which is why fiberboard air ducts are not used for ventilation.
