If your HVAC system's spiral ductwork has become damaged or corroded, you may need to have it replaced. Replacing the ductwork provides you with the perfect opportunity to install ductwork which is made from a different type of material. Below is a guide to 3 common types of HVAC spiral ducting.
Plastic ducting is the cheapest option available when it comes to replacing the HVAC spiral ducting in your home. The duct features a wire frame which provides support for the plastic walls. Aside from its low price, the other major benefit offered by plastic ducting is that it is highly flexible, which means it can be easily worked around obstacles and tight corners. However, plastic ducting is not very strong, which leaves it susceptible to damage, especially if it is used outside.
Steel is a very popular choice when it comes to spiral duct work. During manufacturing, one end of the ductwork will be crimped so that it fits perfectly into other sections. The crimping also makes it super easy to join steel ductwork with existing parts which are made of other materials. The main benefit of using steel spiral ductwork is that it is very hardy and resistant to corrosion caused by moist air moving through the HVAC system. Its immense strength makes steel spiral ductwork the perfect choice for sections of your home HVAC which are exposed to the elements such as sections which link the exterior condenser. The only drawback of opting for steel ductwork is that it is not flexible, which can lead to problems if it needs to be installed around existing pipes and other obstructions.
Fibreglass is a type of plastic which has been specially reinforced using small pieces of glass. It has the same anti-corrosion properties as steel with the added benefit of being lighter in weight. This is especially important if you plan to install ducting on a second or third-floor property, as it will enable the ducting to be easily carried up to the site of the work. Fibreglass ducting is lined with insulation, which helps to trap heat as well as dampen sound, keeping your house cool and quiet. The low-volume hum created by fibreglass ducting makes it ideal if you plan to replace noisy ducting in a study, library, bedroom or another quiet part of your home.
