why is so much cold air coming in?
This is a stupid question I know. I understand the concept of thermal exchange, however I am stumped as to a remedy for my cold weather problem: the extremely cold temps we've been having here in the midwest have resulted in waves and waves of cold air "flowing" from the bottoms of my casement (Norco circa 1996-7) windows. You can feel the cold air just leaking in. The windows are closed tightly. It isn't a breeze, just the cold coming through the thermal panes into the house. Do I have the world's worst windows? Is this normal in extreme cold? My kitchen, which is full of windows, is cold, the countertops under the windows are freezing cold. I thought thermal panes would have more insulation to them.
