Positive Air Pressure
--Jay at 06:22 AM--
One thing that has always seemed strange about the smoke from the apartment downstairs is the appearance that there is positive air pressure. That is, it’s as if their apartment is being pressurized, or air in it fanned upward, so of course it gets forced up through any available opening effectively. Well, yesterday I noticed that the first floor apartment has forced hot air heat! The other two have forced hot water. That explains a lot.
Meanwhile, I did more sealing, mainly to reduce cold air drafts, and that has made the smoke worse. It doesn’t really get worse, but it stays more effectively, and is evident throughout more of the apartment. Doh.
