What Types of Materials are Used in Air Duct Repairs?

When it comes to air duct repairs, professionals rely on a variety of materials to get the job done. From fiberglass and metal sheets to specialized pastes, there are a number of components that can be used to match existing ducts and seal any gaps. Let's take a closer look at the different materials used in air duct repairs. One of the most popular materials used in air ducts is fiberglass.

It is lightweight, easy to work with, and cost-effective, making it a great choice for residential homes. However, fiberglass ducts can be quite noisy when the air conditioning system is running, so they may not be the best option for bedrooms.

Metal sheets

are also commonly used in air conditioning systems. Galvanized steel and aluminum are the two most popular types of metal sheets used in air ducts.

Galvanized steel is coated with zinc to prevent corrosion and rust buildup, while aluminum is lightweight and resistant to corrosion. Metal sheets are great for reducing air leaks in homes, but they can be quite noisy when the air conditioning system is running. Fiberglass-coated sheet metal ducts are also popular in air conditioning systems. These ducts have a fiberglass coating on either the inside or outside of the sheet metal. This type of duct is often used in ventilation grilles for dryers, humidifiers, or when trying to move air through tight spaces or corners.

Stainless steel

air ducts are more expensive than other materials but are often used in commercial buildings due to their flexibility and ability to withstand extreme climates.

Square ducts are also commonly used for both return and supply air ducts. Finally, fiberglass air ducts consist of compressed resin plates that are joined together with inorganic fiberglass. This type of air duct is not naturally porous, so it does not allow mold or bacteria to reproduce in the air ducts.
