    My 30's semi living room, one end is boards, the other is bitumen. Bitumen is higher than floorboards. Q. Can I use the green fibreboards to raise the low, wooden end & then run XPS or the like to underlay the whole room. Thinking the fibreboard would bed better than plywood over the old floorboards but every chance I'm barking up the wrong tree. Thanks in advance.

    Ply the floorboards, cover the bitumen with Ardex NA then use a decent underlay like timbermate or serenity

    Don’t double up on underlay
