Hello,
I'm fitting new kitchen units against two external walls that have suffered black mould - particularly behind the base corner unit where the walls meet. The underside of the wooden worktop is especially badly affected where it touches the wall. Would it help to -
1) Fit a vapour or passive vent behind the units. Like these

2) Cover the wall behind the units with an insulation layer so the wall doesn't get as cold and the worktop doesn't come into direct contact with the wall. (Obviously after getting rid of the mould and treating the surface with anti-mould paint first). Something like this:

3) Both.
I should say that this is in addition to installing extractor fans in the kitchen and the bathroom and following all the usual precautions about wet washing etc.
Thanks in advance.
(I decided to create this post with a specific question after I'd done more research on my rather wordy earlier post.
