Anyway, starting again using Notepad!
I will be lifting floorboards in three rooms - two upstairs and one down - to insulate under the floors. All rooms will be carpeted afterwards.
I am wondering about the advantages/disadvantages of replacing the boards with chipboard.
So far
Advantages:
Smoother surface. Less creaks. Less draughts.
Disadvantages:
More fiddly to lay around odd shaped bits such as bay windows and CH pipes. Harder to lift a small part to gain access to pipes and wires.
I suppose there is also the issue of which insulation is used.
Downstairs I will be using Celotex or similar, so will probably have to lift most or all floorboards, which favours replacement.
Upstairs I could use fibreglass roll and only lift a few runs of boards if I can pull the roll through. I have wondered about using vermiculite upstairs - easy to install with the minimum of board lifting but it does find any cracks, and can be a pain when changing light fittings or fettling lighting wiring.
Suggestions, advice, experience all welcome.
Cheers
