What Is the Most Common Type of Duct?

It’s difficult to say if flat or round ducting is the most common type of duct. That is because each has its own uses and the spaces they are installed in will vary, as well as the needs and usage of that space.

If you’re considering upgrading your ducting, don’t make your choice depending on which is the most common type of duct, instead, you should contact your local tradesman to assess the spaces you have for the ducting, and make an informed choice after that.

Plastic & metal ducting

Flexible ducting

Ducting can come in two forms, rigid and flexible ducting. Both can be made from plastic or metal.

Our flexible ducting hose and pipes can be used for exhausting air conditioning, venting tumble dryers, bathroom fans, HVAC systems and kitchen hoods. Available for purchase with delivery all over the UK. Custom sizes can be fabricated, and UK sales of stocked products over £100 are free of delivery charges.

Plastic ducting

Plastic ducting is usually made from PVC. It is a durable, lightweight material, generally used when installing an extractor fan or passive ventilation system to control condensation or mould growth, you may choose plastic ducting to vent to the exterior of your property too.

Plastic ducting is typically used as ventilation within domestic properties, principally within student flats and modernisations. It is preferred because of its lightness, its airtight properties & durability. It is usually used in rooms such as bathrooms and kitchens, and HVAC systems.

Our lightweight PVC coated ductwork is manufactured from high-quality uPVC and is designed to create minimal air resistance, maximum airflow and minimal pressure loss.

We provide plastic ducting lengths, connectors, bends, brackets, and accessories such as reducers, attenuators and other fittings.

Plastic ducting has a number of advantages including:

• It is lightweight
• It’s easy to install
• It’s smooth on the inside, making for efficient installations
• It is easy to cut
• It doesn’t corrode
• It can be insulated

Metal ducting

Metal ducting are ideal for ventilation systems set up in hotter environments, an example being a cooker hood.Metal ducting is also a popular choice for spaces and environments with air rich in certain compounds that could be hazardous or damaging to standard choices.

HVAC experts and engineers typically choose to rely on stainless steel for aggressive environments, where corrosion is highly likely.

We provide round ductwork fittings and accessories in a large range of diameters to suit all purposes including HVAC systems and extractor fans. Our metal ductwork is manufactured from high-quality galvanised Aluminium.  

The benefits of metal ducting are as follows:

• It can be used in rooms that have appliances that emit a lot of heat
• High-quality galvanised aluminium ensures long-lasting function
• Ideal for industrial environments
• Can be insulated.

The effects of no ducting

Having no ducting or ventilation in your home will result in the buildup of condensation and mould as well as exposing you to potentially harmful chemicals.

Opening a window will not be enough to efficiently and consistently remove any air impurities. Extractor fans and cooker hoods actively intake the air, and will do so unless you turn them off (some have timers after switching off.)

A way to understand the necessity of ducting would be to compare it to having a coal or wood-burning fireplace with no chimney. If the smoke did not escape through the chimney, smoke, its smell, its toxicity and its staining would be everywhere no matter how long you keep the window open.
