I have a garden window in my kitchen and when the weather turned cold I
noticed air infiltrating along the bottom edge. An installer came by to fix it and said it is a function of the window as it is outside the house and the glass is exposed on 3 sides plus the top, and the air on the inside
is cooled by the outside and falls to the bottom of the window. The glass IS double paned, but I do not know what, if any, gas is insulating it.
Is this true that it is the nature of the window?
Thanks!!
