 But what happens downstairs, I try to insulate around the doors with some of that foam tape. And I even have the little sleeve in front of the door that kind of blocks the air coming up from below the door. But it's still really cold. Like now the first floor is kind of like our basement half finished. And then there's a garage on the other half. And you have to kind of walk upstairs to get to the first level of living, kind of basically the living room, the kitchen, dining room.
