BSRIA, the consultancy, test, and research organisation for construction and building services, has published a guide to Flexible Ductwork. Hard copies are now available for £30, or £15 to BSRIA members, while PDF versions cost £30 + VAT, or are downloadable free by BSRIA members.
The guide’s development included a review of Approved Documents of the Building Regulations, British and European standards, industry guidance literature produced by organisations such as CIBSE and B&ES, manufacturers’ technical guidance, and a wide range of construction project specifications.
