Homeowners often wonder, what is ductwork made of? This is a fair question, as knowing more about its construction can help ensure you maintain it properly. You might also understand some mistakes to avoid when it comes to cleaning and repairs.
In most cases, manufacturers use thin sheet metal to create residential ductwork. Also, plastic and wire coil create flexible ducts, used to work ducts around obstacles. Ductile iron, PVC, and other materials are commonly found in commercial properties but not so much in residential homes!
This is just a quick summation of ductwork materials. Some added details about ductwork, HVAC features, and other installations are helpful for any homeowner. Also, if you’re concerned about your property’s condition, call an HVAC repair contractor near you. They can perform expert inspections and repairs when needed.
Manufacturers use various materials for ductwork, used to distribute air for heating, ventilation, and air conditioning systems. Chosen materials depend on the intended use, budget, and specific requirements of the installation. Some common materials used for ductwork include:
Sheet metal, typically galvanized steel or aluminum is a common material for ductwork. This material offers excellent durability and fire-resistant properties. Manufacturers can also easily fabricate sheet metal into various shapes and sizes to suit different HVAC needs.
These ducts are made from a combination of plastic and wire coil, covered with a flexible and insulating material. Flexible ducts are used when installation space is limited. Also, flexible ducts can be routed around obstacles such as framing, pipes, and the like.
Dryer hoses are an example of flexible ducts. You might notice the flexibility and strength of these ducts. The flexible material also allows you to twist the duct around the back of the dryer to a nearby vent.
This type of ductwork is made from fiberglass insulation materials formed into panels with an aluminum facing. Fiberglass is used in situations where thermal insulation is important. It combines both the duct material and insulation in one.
It’s not likely that your home has ductile iron ductwork. Ductile iron is strong and durable, often used for larger commercial or industrial ductwork systems. It's less common than sheet metal in HVAC applications but can be used for specific purposes.
For example, ductile iron can handle higher temperatures than other materials used in HVAC ductwork. This makes it suitable for conveying hot air or gases in industrial settings where extreme temperatures are involved. Also, ductile iron's durability and resistance to corrosion and abrasion make it a suitable choice for air containing corrosive chemicals or damaging.
PVC ductwork is often used for exhaust and ventilation systems in corrosive environments, such as chemical laboratories or industrial facilities. However, it’s not used commonly in residential settings. Sheet metal often provides the durability needed for most homes at a more affordable price.
Fabric ducts are made from permeable fabric materials. These are used in applications where air distribution needs to be diffused more evenly. This includes commercial spaces like retail stores or gymnasiums.
Pre-insulated duct panels are made from insulating materials sandwiched between layers of sheet metal. They provide both insulation and duct material in one package.
The most common material used in ductwork fabrication is sheet metal, typically galvanized steel or aluminum. Here's a breakdown of why manufacturers use these materials more often than others:
Both galvanized steel and aluminum offer durability, fire resistance, and flexibility for fabrication. The choice between these materials often depends on specific HVAC requirements, budget, installation environment, and personal preferences.
Determining whether your house needs new ductwork involves assessing the condition of your existing duct system. You’ll need to check various factors related to its performance and efficiency. Check out some signs that might indicate the need for new ductwork:
