hi there
just been reading thru the ESC best practice guide 5 " Electrical installations and their impact on fire performance" it indicates that when running ducting from a bathroom fan vent along a void parrellel to joists in a floor or loft space that the joists have to be provided with fire protection for example lined with plasterboard. to protect joists from fire entering the vent and burning thru duct.
i have never seen this done,ducting is usally just laid accross the insulation covering the joists. any views or examples of what you do?
