The ductwork is a crucial module in the function of your commercial HVAC system. This component is responsible for conveying cooled or heated air to the interior spaces of your building. Therefore, its functionality will affect the energy efficiency of the system as well as its expediency in fulfilling your climate control objectives. If you are installing a new central HVAC system or replacing your old ductwork, it is important for you to choose the right air ducts. Here is a brief outline of the main types of ducts to consider using for your commercial space.

Stainless Steel Sheets Ducts

Sheet metal is commonly used in the production of long-lasting air ducts for HVAC systems. In the residential setting, these metallic ducts are primarily manufactured using aluminium or galvanised steel. Typically, these materials can be utilised in the commercial environment, but they are vulnerable to accelerated damage when exposed to heavy usage. Therefore, if you would like an alternative which is more long-lasting, consider selecting stainless steel ducts. This material is stronger than aluminium and can withstand exposure to moisture without degradation. These ducts are available in rectangular and circular shapes. For optimal performance, make certain that the ductwork is insulated sufficiently and that the different sections of the tubing are connected using sealant or tape.

Flexible Ducts

The unique construction of flexible ducts makes the option ideal for long-term commercial applications. In general, this type of product is fabricated by covering a continuous steel wire with polymer plastic, such that a tube is formed. The duct produced is extremely lightweight, which makes it easier to install. In addition, the construction materials are easily accessible and inexpensive, making this an economical choice. Flexible ducts are ideal for your building if you cannot conveniently install rigid alternatives due to space constraints. In simple terms, these work well if the duct space has an unusual pattern, and they can be threaded through obstacles. When installing, ensure that the ducts are stored safely to avoid mechanical impact and punctures.

Fibreboard Ducts

A fibreboard duct is constructed using compressed inorganic glass fibres; these are bonded using special resin. The main advantage of this duct option is its great thermal insulation, which promotes energy efficiency. Unfortunately, the material is relatively porous, so it is vulnerable to damage by water and mould growth. Therefore, the outer surfaces are usually covered with a water vapour retarder in the form of foil. Additionally, the interior surface should be sealed to prevent release of glass fibres into circulation.
