Hello
My bathroom in my loft conversion needs an extractor fan. I will be using a remote inline fan.
See below. the red dot would be where the ventilation grill is. the red line is the 100mm ducting.
However, this can only go between the rafters where the PIR insulation board will be fit..... so do I cut a 100mm tunnel into the back of the insulated board, and use insulated ducting?
Thanks
