Before i start considering work on the new structural loft floor, should i remove the grubby 1970s floor fiberglass insulation ?
Dirt and dust has collected because the roof (to be replaced etc) has no felt layer. I suspect the insulation properties of the fibre glass has deteriated, due to dirt and compacting ?
