Differences between flexible air ducts and regular air ducts: Which type should you choose?

In the ventilation – air conditioning system, choosing the appropriate type of duct plays an important role in ensuring operational efficiency and cost savings. The two most popular types today are soft air ducts and regular air ducts (hard air ducts). So what is the difference between these two types? Let’s find out below to make the most accurate choice for your project.

1. Characteristics of flexible air ducts

Flexible Duct is usually made from aluminum, aluminum-coated fabric, or PVC reinforced with a twisted steel core. Some types also have insulation made of glass wool or PU foam.

Advantage:

• Flexible: Easy to bend, installed in difficult locations such as narrow ceilings, limited space.
• Quick installation: Saves construction time and labor costs.
• Noise reduction: Thanks to its soft structure, the tube helps limit vibration and noise in the system.

Disadvantages:

• Not as durable as hard air ducts.
• Not suitable for systems requiring large air flow or high pressure.

2. Characteristics of regular air ducts (hard air ducts)

Regular air ducts (hard air ducts) are usually made from galvanized steel, stainless steel or aluminum, in rectangular or round shape.

Advantage:

• High durability: Withstands great pressure, suitable for industrial ventilation systems.
• Stable performance: Keeps the airflow even, without collapsing or deforming.
• High aesthetics: Easy to paint, neatly installed in commercial buildings.

Disadvantages:

• Difficult to construct in areas with limited space.
• Material and installation costs are often higher than flexible ducts.

3. Which type of air duct should I choose?

Depending on the intended use and project conditions, you can choose the appropriate pipe type:

• Flexible air ducts: Suitable for diversions, tight spaces, residential houses, or the end of the system.
• Rigid air ducts: Ideal for main systems, large buildings, factories, commercial centers or places where high performance is required.
