We have a door and a window that open out onto our balcony. It's too hot to keep them closed for very long, but the person below us smokes. the smoke comes up between the boards and in through our windows. And he's out there it seems once every hour. So we have to keep shutting our windows and reopening them when they're gone. Does anyone have any suggestions as to something we could maybe put down, a rug or plastic, that would keep the smoke from coming up. I know the apartments are supposed to be smoke free, but I don't think there's anything about smoking on the balconys.
