其实这里房子冬天室内湿度都很低,一般在30左右,不存在湿度过高的问题。主要问题是窗户保温不好。外面温度很低时,室内窗户还会结冰。我的解决办法是:remove inside sidings for all windows and doors, redo undulations and seals; in summer time re seal out side frames for all windows and doors. Then increase the temperature inside. It helps a lot. But the best way is to replace with new windows and doors with good insulation. Add more insulation for the house if necessary.
