Ductwork is the portion of the HVAC system that we tend to overlook, even though it provides one of the most critical functions. Air ducts are the conduits that distribute cooled or heated air throughout the structure, and without them, the entire HVAC system would be ineffective. Several types of air ducts can be utilized in a home or commercial building, each with its own set of benefits and drawbacks. An HVAC professional can advise you on the best type of ductwork to utilize based on your HVAC requirements. Ductwork is divided into two types: flexible and stiff.

Types of Duct Systems:

Duct systems are classified into three types. There are three types of ductwork: 

  • Flexible ducting
  • Rigid ductwork
  • Semi-rigid ductwork. 

We’ve gathered data on each of these duct systems.

Flexible Ductwork:

These ducts are generally tube-shaped and constructed of a wire coil wrapped in pliable, durable plastic and enclosed by insulation. Flexible ducting works best in intricate and tricky places were installing or using rigid ducts to connect non-flexible ductwork to a supply air outlet is impractical. Flexible duct systems, like the majority of central air conditioning components, have unique installation requirements. Flexible ducting, for example, must be properly fastened and supported to avoid sagging or snaking. Bends and kinks must also be avoided since they limit airflow and reduce the efficiency and efficacy of the air conditioning system. The benefits of employing flexible ducts include rapid and easy installation, as well as lower costs than rigid ductwork. You can get your AC duct cleaning from octopus in dubai.

Rigid Ductwork:

Rigid duct systems are available in several materials and sizes, and they can be rectangle or tubular. These ducts are frequently insulated. They are widely used because they are tough, long-lasting, and dependable. There are three main types of rigid duct systems:

Sheet Metal Ducts:

If you enjoy watching action films, you’ve most likely noticed sheet metal ducts. They are the ducts that you see in movies where the main character crawls through the air ducts. Galvanized steel and aluminum are the most commonly used materials for sheet metal ducts. Aluminum is a lightweight material that is simple to install. Because of their non-porous surfaces, these substances are also the least prone to host harmful molds or growths.

Fiberglass Lined Ducts:

Fiberglass-lined ducts are similar to sheet metal ducts, but they contain an internal fiberglass lining. This duct system is more frequent in retail and office buildings since it helps to muffle the sound of the air – conditioning unit. Unfortunately, the fiberglass in these ducts is prone to deterioration and eventually releases fiberglass particles into the air, which can pose a serious health risk, particularly with extended exposure. Furthermore, fiberglass-lined ducts are difficult to clean since the cleaning process can tear the lining and release fibers. Molds and bacteria can taint these ducts as well. 

Fiberboard ducts:

Fiberboard ducts are made of crushed and glued fiberglass strands that are covered with a foil lamination covering for moisture protection. Because they are effectively insulated, fiberboard ducts are ideal for cooling and heating systems. However, we do not advocate it for ventilation since, like fiberglass-lined ducts, it can become a breeding place for mold or mildew in humid regions. They also have hard edges, which might interfere with ventilation and effectiveness.

Semi-Rigid Ducts:

Semi-rigid ducting is regarded as the greatest type of airflow ducting available, and it provides installers with some advantages. Because it is a zero leakage ventilation system, superior quality semi-rigid ducting assists a ventilation system is operating at top performance. High-quality semi-rigid duct systems, on the other hand, have a high crushability level. Furthermore, some semi-rigid ducting systems give the installer flexibility by allowing him to swap between round and oval ducting without affecting hydraulic pressure or the operation of the system. Because many semi-rigid duct systems contain anti-bacterial and anti-static inner lining, it is also easier to maintain.

Final Lines:

The general design of your home, your demands for heat retention or noise reduction, and your budget all play a role in selecting the correct ductwork for your home. Ductwork’s function is to route air from your HVAC unit and disperse it to various areas of your home. Simply explained, if you didn’t have ducts, each room in your house would be a different temperature. Each Duct system has advantages and disadvantages. As a result, it’s critical to understand each one before making a selection for your project.
