Wind flow between rec room and room above it
I was replacing the lamps of my rec room with recessed lights, and while doing that I noticed that there was a cold flow of air in the gap between the roof of the rec room and the floor of the room above it.
That might be normal...or it might not be, and that's what I'm trying to understand. I'm afraid that it is just a way for heat to escape and cold to enter into my place.
Your post is a little confusing. How can it be a roof if there's a room above it?
I'm guessing you mean the ceiling in the rec room.
What's the ceiling made of, sheetrock suspended?
Where the duct work run? Is it between the ceiling and the floor above?
Pretty commonplace with platform framing and even worse with balloon framed homes.
Is there a cantilevered part of the home? They are notorious for being un-sealed and leaking.
Use an air tight can if you have them.
If you have a cantilevered floor, get it sealed up with rigid board and foam.
My guess would be ballon framing if it's a really old house.
Balloon framed or cantilevered would be my guest.
