What Is The Best Material For Ductwork?

With so many competitive duct products in the market, it would be too challenging to select the perfect duct for the HVAC system. Yet, you will have to look at the different compressors and condensers to find out the perfect match for the HVAC system.

What is the best material for ductwork? You can use four kinds of air ducts: the Sheet Metal Air Ducts, Fiberglass Lined Air Ducts, Fiberboard Air Ducts, and Flexible Air Ducts. These air ducts produce the best results when placed in central air conditioning.

This article will learn about the different kinds of ducts and the importance of ducts in the HVAC system.

Kinds Of Air Ducts

Ducts are used to heat and ventilate in air condition effectively so it could efficiently deliver and filter outside air. Here are the lists of the air ducts:

Sheet Metal Air Ducts

The Sheet Metal Air Ducts is the most common duct to use and is made of galvanized steel or aluminum. One good thing about aluminum is its light-weight and easier to install compared to other air ducts.

The sheet metal air ducts feature is also thick enough not to be easily getting crushed when someone steps on it. Sheet metal air ducts are also the most durable among all types of air ducts construction. However, molds can stick on it due to its non-porous surfaces.

Fiberglass Lined Air Ducts

FIberglass Lined Ducts either have internal or external fiberglass lining, which can be found in commercial buildings. It is also good in small offices because it would dampen the air conditioner’s annoying sound.

The disadvantage of using Fiberglass Lined Air Ducts is its short-term deterioration and the dangerous release of fiberglass, which can be a potential danger to anyone’s health. Also, fiberglass can be challenging to clean because it can be easily contained with molds.

Fiberboard Air Ducts

Fiberboard Air Ducts are made of resin combined with inorganic glass fibers, which can be an air barrier and water vapor retarder at the same time. Its interior is perfectly sealed to stop outside stale air from entering the air stream.

It can give thermal benefits to your house, as the fiberboard air ducts can insulate itself very well. However, this is not recommended for ventilation because molds can easily stick to it, which can affect the airflow.

Flexible Air Ducts

The most popular type of duct is the flexible air ducts, which are typically made of spring steel wire helix and polymer plastic. These types of air ducts are like the Sheet Metal Air Ducts, which can be easy to install and inexpensive.

It is interesting to use them because the installation is easier than other air ducts, that’s why many preferred to use this at home. Before installing the flexible air ducts, ensure that you have a Green ID installer to ensure that the air ducts are properly installed.

On the other hand, flexible air ducts can be the worst for airflow because they restrict airflow. However, the advantage of using flexible air ducts is its production of good air quality. So far, this air duct is also resistant to bacteria and mold, so you don’t have to worry about cleaning it.

Importance Of Air Ducts

Air ducts are known to be an essential part of the HVAC system because they’re used only to allow good airflow towards the room. When the air duct is correctly maintained, it functions very well in conditioning and heating your house.

Air Ducts Serve As Pathway For Air

Air Ducts are the reason why air can circulate cleanly inside the room. One of its primary responsibilities is to remove potentially dangerous airborne particles that could affect everyone’s health.

When the air is cleansed, it will move back to the air ducts to produce cooler air around the room. If the air duct system is not well-maintained, it can be a source of expensive electric bills and home discomfort.

Air Ducts Prevent Air Contamination

An effective air duct’s main job is to filter not only stale air from the outside environment, but also dust, dirt, and other contaminants that prevent you from having a healthy atmosphere.

Just in case the air ducts are leaking, then the contaminants can also leak all over the place. If this happens, the contaminants might cause allergic reactions and asthmatic symptoms. If you learned to keep the air ducts in good condition, expect it to return the favor.

Air Ducts Facilitate Efficient Ventilation

Air ducts have undoubtedly become an integral part of the HVAC System because they facilitate centralized ventilation throughout the facility, therefore offering a more comfortable environment for everyone.

If you considered all the benefits air ducts can give to your office or home, it would keep you maintaining it at least once a week. At the same time, air ducts can be bought at affordable prices.

Air Ducts Can Save Energy

You might be shocked when your monthly electric bill started to get higher. It is due to the improper installation of air ducts that could cause an inefficient power saving system. So, it’s better to be meticulous with the air ducts because of its power-saving benefits.

You’ll notice how beneficial it was not only to your bills, but also the feeling within the premises. A functional air duct can make the whole room cooler by centralizing the air.

Air Ducts Prevents You From Acquiring Diseases

If the air ducts aren’t functioning well, you might consider changing or reinstalling it because it will only cause drastic respiratory diseases, such as asthma and chronic allergies.

Each air duct is designed to filter bad air from being distributed across the room, so it’s essential to have either cleaned or replaced when it’s broken. Besides, air ducts are very easy to install, so both the maintenance and the installation won’t give you headaches anyway.

Air Ducts Balances The Return of Airflow

Another advantage of having an air duct in the HVAC System is the balanced supply of airflow return that’s evenly distributed within the room.

With this, the air duct will be needed to minimize temperature gains by keeping the supply registers and the air handler discrepancies. If the temperature’s result is either too high or too low, then it will cause an electric bill increase.


Just in case you are experiencing ineffective cooling or improper ventilation, then expect that there might be a big problem with air ducts. Air ducts are inexpensive and practical, so you can buy a replacement if it’s not fully working.

If you are experiencing some issue installing, ask for the help of an HVAC System Technician. A professional can also educate you with its benefits. Air ducts are usually known for their longevity and durability, so sealing the right air duct depending on your HVAC System’s needs would matter.
