SPECIfICATION fOR SHEET METAL DUCTWORK

THE INDUSTRY STANDARD

Bob Lane Peter Rogers

Chairman Chairman

Executive Committee Technical Committee

Ductwork Group Ductwork Group

Since its publication in 1998, the Association’s Specication for Sheet

Metal Ductwork –DW/144 – has gained national and international

recognition as the standard against which the quality of ductwork

manufacture and installation can be measured.

However, developments in technology and working practices, along with

the need to reect a steady proliferation of European standards, have

rendered necessary a far-reaching revision of the original edition.

This second edition is the result of many years of work by members of the

Technical Committee of the B&ES Ductwork Group (DWG), who have

expanded the content on such subjects as:

• supports and hangers;

• smoke and re dampers;

• external ductwork;

• internal duct linings;

• thermal insulation;

• air terminal units;

• re-resisting ductwork;

• ductwork for swimming pools, etc.

Of course, a key element of any such review is to ensure that the

specication continues to oer realistic benchmarks to which all

individuals and organisations are able to perform.

DW/144 now incorporates B&ES publication, Acceptance Scheme for New

Products: Rectangular Cross Joint Classication (DW/TM1), which

establishes performance ratings for both air leakage and deection for

cross-joints.

In order to validate the parameters set out in DW/144, B&ES has

undertaken extensive testing against recently-introduced CEN

requirements to measure panel/ange deection and air leakage testing.

Testing has also been undertaken to determine the lifespan of untreated

spot welds over a 30-year period.

The results have allowed the DWG Technical Committee to make a

number of recommendations in relation to the construction of ductwork

which oer a signicant commercial advantage. These include:
