I have seen a house for sale which I want to put an offer in on. It is a 3 bed Victorian terraced house with bay windows and high ceilings. Only the front rooms with bay windows in have been double glazed with wooden glazing. Why not the rest of the house (lots of windows!)? I have seen the same in another house for sale. Does this mean I can stop worrying that the house will be freezing as maybe the rest of the house is okay?
