Hello everyone I understand that humidity changes, however I have no doubt that there is a standard. It’s this that I am looking for. As the new builds from what I have been told are vacuumed sealed and air is put in under pressure to find any minor air leaks. So on such a build as this, when there’s nobody living in the building there will be a humidity that that building will be at. At the very least there will be a range. So then when we look into the older builds there are some key differences, from the new builds. I’m now looking into the hows and whys. As I find it interesting that the new builds have a humidity that super dry that your throat hurts, and yet in some buildings that this is not the case. After all there are not to many differences. So I would be grateful of any advice. Thank you all in advance.
