Anyone know what DW144 is?

[Mark]

Hi chaps, anyone in duct work? If so you may know what the above reference is. Looking for a copy . A bit far fetched question but worth a try!

DW/144 is the Building Engineering Services Association (BESA) specification for sheet metal ductwork. I believe the current version is the Third Edition 2016.

Hope that helps. Not able to provide a copy though.

That’s the one but was looking for a copy that’s all.

Are you a member of the BESA?
