Hi everyone,
Here is my first attempt at the BS 4.0 vignette. I'm not sure about the placement of the rigid duct as one of the criteria is that rigid ducts do not fit through the joists. How do you know if the duct is going through a joist? Also, is there a particular way that fire dampers should be placed in the bearing wall?
I'm testing this Saturday. Thanks in advance for your feedback.
