Welcome to the Ductwork Group
The Ductwork Group was formed 65 years ago to focus on the particular technical and business issues relevant to ductwork contractors and fabricators.
It has gone on to produce some of the industry's most influential technical specifications including the industry 'bible' DW144 - Specification for Sheet Metal Ductwork; and DW172 - Specification for Kitchen Ventilation Systems.

Its latest work DW145, which focuses on the installation and testing of fire and smoke dampers, has been endorsed by fire authorities, surveyors and consulting engineers.
