One of the previous owners built a brick & wood framed conservatory from a kit. We recently discovered that all the joists were rotten, some more than others.
The conservatory has no air bricks so my plan is to add air bricks and replace the joists. However between the joists and the chipboard flooring the guy had put down some thin plastic sheeting (which almost looks like cling film) and I was just wondering if it makes sense to do something like this?
