Hello, I have a conservatory off the kitchen with 5 large double glazed windows and french doors. When I open the kitchen door the 4 of the windows and one of the french doors steam up, but the other window and door remain clear. My thinking is that some of the dg units are fitted the wrong way round. If so, how do I tell whether it is the units that stwam up or the ones that remain clear?
Hope someone can help!!
