I have torn down a lot in our hallway to find the reason why it is so cold. I found some holes where cold air was being sucked in. But since I removed the ceiling, walls, and floor, I now don't feel if or where there is a draft. If there is still a draft somewhere, I suspect I will feel it when I've put most things back in place. The way things were built when I tore them down, the walls locked the floor in place so I had to tear down a lot. I thought that now when rebuilding I should try to build in such a way that I can lift the floor without having to worry about the wall and vice versa. But I wonder if that causes problems that I can't see.
It looked roughly like this before I tore it down:
i.e. to lift the floor I had to take down both gypsum board and masonite board as well as the innermost layer of studs and insulation.
I thought if it could be moved out further so it aligns with the edge of the wallboard?
