Top Suppliers in West Bengal List the Different Types of Air Ducts

In case you didn’t know, the two main functions of an air duct are to distribute air through a building and exhaust air out. It is one of those components that is usually quite inconspicuous, meaning that you don’t realise its existence unless it malfunctions. There are quite a few types of materials that are used to manufacture an air duct. Ducting fabrication suppliers in West Bengal discuss the materials that are used for the purpose.

Here are the Types of Material an Air Duct Can be Made From

1. Sheet Metal
The most popular and hence common material which is used to make an air duct is sheet metal. Most rigid ducts are made from sheet metal which, in turn, is made out of galvanised steel or aluminium. The shapes that an air duct made from sheet metal can come in are rectangular, round or a spiral oval. The reason why steel metal air ducts are so popular is that they are the most durable. Ducting fabrication suppliers in West Bengal primarily prefer this material for their construction.

2. Fibreglass-Lined
There are certain types of sheet metal air ducts that are lined with internal or external fibreglass duct liner. This ensures that the air duct remains insulated from heat loss, and avoid condensation in case the supplied air is extremely cold or if the ambient humidity in the plenum is too high. If these factors were not enough, fibreglass-lined air ducts make considerably lower sounds than those that do not have this feature. 

3. Fibreboard
Air ducts made from fibreboard are basically constructed with the use of compressed boards of resin bonded with inorganic fibreglass. This system has a foil face on the external surface which serves as an air barrier and water vapour delayer. On the interior of the fibreboard air duct, the surface is sealed so that the entrance of glass fibres into the air stream is restricted. Fibreboard air ducts are the most expensive type of ducting system. There are also acoustical and thermal benefits of this type of ducting material.

4. Flexible Air Ducts
Another popular type of air ducting system, flexible air ducts are sought-after due to their inexpensive nature, light weight and ease of installation. These types of ducts are made with a spring steel wire helix which is encapsulated within a 2-ply polymer plastic. It has to be kept in mind that the length of the air duct must be at a minimum due to the fact that with every bend there is, the performance gets significantly compromised.

These are the most popular types of air duct systems. Now that you are more aware of them, you will be better informed when you meet ducting fabrication suppliers in West Bengal.
