18 Jan Common Types of Ductwork
Ductwork plays a crucial role in commercial properties’ heating, ventilation, and air conditioning (HVAC) systems. It helps distribute conditioned air throughout the building, ensuring a comfortable and healthy indoor environment. There are several different types of ductwork available, each with its own unique set of characteristics and benefits. Here are some of the most common types of ductwork found in commercial buildings:
Rigid ductwork is made from plastic or metal and is ideal for long runs of straight ducts. It’s strong, durable, and easily sealed at joints to ensure an airtight connection. The downside to this type of ductwork is that installation can be challenging due to its lack of flexibility, which may not suit complex or cramped layouts.
A flexible duct is made of a semi-rigid aluminium foil-faced insulation coated with a layer of plastic. It’s flexible and easy to install, making it a popular choice for HVAC systems in commercial properties. Flexible duct is also lightweight, easy to handle, and resistant to moisture and mildew. However, it’s less durable than other types of duct systems and may not be suitable for high-temperature or high-pressure applications. It’s also prone to sagging over time, so it should be adequately attached and supported.
Galvanised Steel Ductwork
Galvanised steel ductwork is made of sheets of steel coated with a layer of zinc to prevent rusting. It’s a durable and long-lasting option that is resistant to corrosion and damage. Galvanised steel ductwork is often used in commercial properties with high heating and cooling demands, as it can withstand high temperatures and pressures. However, it’s also heavy and may require additional support when installed. It’s also one of the more expensive types of ductwork.
Aluminium ductwork is made from sheets of aluminium coated with a layer of paint or enamel to prevent corrosion. It’s a lightweight and flexible option that is easy to install and handle. Aluminium ductwork is also resistant to moisture and mildew, making it a good choice for damp or humid environments. However, aluminium is prone to denting and can vibrate in certain conditions, which may lead to noise transfer. Overall, aluminium ductwork is a good choice for those who need an affordable and lightweight material that offers some corrosion protection.
Fibreglass ductwork is made of fibres of glass that are coated with a layer of resin or plastic. It’s lightweight, easy to handle, and resistant to moisture and mildew. Fibreglass ductwork is also a good insulator, helping to reduce energy consumption and costs. However, fibreglass ductwork is prone to cracking and may need frequent maintenance. Additionally, fibreglass ductwork can be difficult to repair and replace if it becomes damaged or wears out.
Fibreboard ductwork is made of wood or paper fibres coated with a layer of resin or plastic. It’s a lightweight and flexible option that is easy to install and handle. However, it’s not as strong as other ductwork types and can be easily damaged by chemicals or solvents. It’s also more prone to mould growth than other materials.
No matter which type of ductwork you choose, make sure that it’s properly installed and maintained by a qualified contractor to ensure maximum efficiency and performance.
A professional contractor should be able to assess your needs, recommend the best type of ductwork for your HVAC system, and provide installation and aftercare services. With proper installation and maintenance, you can ensure that your HVAC system operates efficiently and safely for years to come.
