Bathroom ceiling has developed mould
So I went into the loft and noticed that every other room (except for the bathroom) had 100mm of mineral wool insulation installed.
So I laid 100mm insulation between the joists in the bathroom ceiling. No vapour barrier.
Is this enough or is it recommended that i top the bathroom area to 270, 300 etc?
The bathroom also has a powerful inline fan installed
