I am going to be adding windows to my home. Currently I have double paned windows. I am going to install new windows on the interior side of the exsisting windows. I am not going to remove the older windows. Most of the windows are view windows and do not open. My question is if I put in windows that do not open will the glass on the inside of the new and old window fog up? If so, what can I do to prevent this. For the sake of preventing enery loss, I do not want to the inside window to open, but if there is no way of preventing this formation of fog, I guess I will.
