What is an Air Duct? Understanding the Basics of Air Ducts

What is an Air Duct

When you live in a home, its cleanliness and health become your top priority. So, you need to do everything in your power to make your home as clean as possible. One of the parts of your home that play the biggest role in keeping the home healthy is your air ducts. But what is air duct? 

Air ducts are oval or rectangular-shaped ducts that filter the air inside your home. These ducts then supply the filtered air back inside the house. There are many kinds of air ducts, such as sheet metal, flex, fiberglass, fabric ducts, etc.

Here is everything you need to know about air ducts. 


What do you mean by an air duct?

Air ducts are a system of ductwork that provide passages for the air inside your home to be filtered by the air filters. These same ductworks are also responsible for supplying the filtered air inside the house. The air that is passed through the air ducts also travels to the HVAC units and is then warmed or cooled by them. This warmed or cooled air is also supplied to the rooms by these air ducts.

How many types of air ducts are there? 

Although the goal of air ducts, irrespective of their types, is the same, some air ducts are much different than others in terms of material and what type of home they are suitable for. 

These are the different types of air ducts that you can have in your home or commercial building:

1. Sheet metal ducts

Sheet metal air ducts are probably the most common type of air duct in the world. These ducts are made from galvanized metal sheets, such as steel or aluminum. This not only makes them resistant to rusting but also makes them durable and strong. 

If you are looking for a rigid and strong type of air duct, then you should go for these ducts. These ducts are also capable of handling high air pressure. Since they are made of metals, they can be made into various shapes, such as round, rectangular, oval, etc.

2. Flex ducts

Flex ducts, or flexible ducts are as their name suggests, very flexible. While sheet metals are good for their strength, their rigidity can be a big issue in terms of the structural integrity of the buildings. In this case, you can install flex ducts in your homes that are made of flexible plastic.

These plastic ducts are then reinforced with wire coils or helix reinforcements. This type of air duct is one of the easiest to install, and they are perfect for places where installing air ducts, especially sheet metal ones, is quite difficult.

3. Fiberglass ducts

Fiberglass air ducts are one of the more modern variants of air ducts. These ducts are constructed with panels or boards made of fiberglass. As a result, they have great insulating properties while also absorbing a lot of noise. 

These ducts are very suitable to regulate heat properly and efficiently. So if you have a commercial building or a building where the need to regulate heat properly for a long period is necessary, then you should go for fiberglass ducts.

4. Fabric ducts

These unique air ducts are also called air socks, since they are made of fabric, instead of the more rigid materials mentioned above. The fabric used to make these ducts have numerous pores in them, which facilitates greater air circulation. 

If your home has a high air velocity, then you can go for fabric ducts to reduce it, and also the noise that is made in the ducts. Since they are full of pores, these ducts also will provide you with improved airflow and quality.
