I have just taken up a rotted foam backed carpet from my study. When I put it down I had followed the advice at the time which was to line the floor with a thick paper.
When I chose a replacement carpet and proper underlay I asked if they still put a paper down first. They said not.
What is the advice of the group? The floor is chipboard. There are some T&G boards near the door that extend from under the bathroom wall.
Will I get any benefit from putting a layer of thick paper on the floor?
