HVCA works towards revising ductwork specification

The industry’s specification for sheet-metal ducting (DW/144) is being revised by the technical committee of the ductwork group of the Heating & Ventilating Contractors’ Association. Proposals for revision and suggestions for new items to be included are welcomed from all sectors of the building-services industry. A ‘tracker’ document has been devised which lists the proposed amendments in a tabular format; it is available to all interested parties. Copies of the tracker document are available from gkeller@hvca.org
