    Lifting 120 year old floor and insulating - Bit lost...need help!

    Im in the process of lifting my floors and removing the slag/burnt rock insulation. There is a layer of whitish plaster which I assume is horsehair between the joists. Is this just to keep the slag in or is there some other reason. Ive also got a sickly sweet smell coming from the floor. I guess...
