ADCAS (the Association of Ductwork Control Contractors and Allied Services) is calling on the construction industry to pay attention to quality when purchasing ductwork.

Ductwork is a very important element of a building and is often overlooked at the design and specification stages. However, it influences energy efficiency and indoor air quality. As a result, it can impact on occupants’ health and wellbeing, as well as long-term operating costs.

ADCAS believes that low-priced ductwork can be linked to poor quality in the manufacturing and installation processes. This in turn leads to poor outcomes for building owners and occupiers.

President Malcolm Moss said: 'Ductwork should not be bought solely on the basis of cheapest price. This almost inevitably leads to under-performance of air movement systems that will have a significant impact on the operation of a building in terms of both cost and comfort.'

Ductwork is a technology that requires experience not only in manufacturing, but also in dealing with the challenges that can arise on site when installation is underway.

Mr Moss continued: 'This is a key area where quality and expertise matter. ADCAS members have knowledge and experience so they know how best to install and contract projects so that works are carried out smoothly.'

What’s more, there is a host of legislation and guidance on ductwork that specifiers, contractors, and building owners should be aware of. The legislation covers fire safety, cleaning, manufacturing and installation standards. It is important to consider whether a ductwork supplier understands the industry standards and rules.

In order to measure up to these regulations and to enhance the lifetime performance of ductwork, specifiers and end-users should deal with reputable suppliers at all times. ADCAS has recently published a Guide to Ductwork Cleaning & Access which highlights the sort of rules that reputable ductwork manufacturers and installers should be aware of.

Mr Moss said: “Contractors who choose to go down the cheaper route when purchasing ductwork are more likely to get poor quality product. Those who are looking for a whole-life product should be dealing with reputable suppliers, such as members of ADCAS, and thinking about the long-term costs of their ductwork selection.”
