How high does the temperature have to be outside to avoid condensation inside?
Your question assumes 2 things wrongly. 1, that cold air outside will cause condensation inside, the answer to that is that it might and it might not. 2 that there is some temperature where this will cease, again there is and there isn’t. Condensation is caused by cold air hitting a warm surface, and also lack of air circulation. Hence why a greenhouse that is warm inside on a hot day, can have condensation, its all relative. No I don’t know the temperature difference. If you are suffering severe condensation on windows and walls in your house or where you work, this is most likely caused by not leaving the heating on, on a low setting when you are out, and then putting it on high when you get in. It is the fabric of the room which is cold, so this makes condensation until it starts to absorb the heat when you turn it on. The easiest way to avoid this is to leave a low heat on, then the room doesn’t cool as much, you also benefit from not having to put the heating on full for anywhere
