I had a builder round on friday (not a euphemism - one really did visit) to check a dodgy partition wall that is supporting a couple tons of roof on a rotting wood frame and needs replacing by an RSJ.
Anyway, on seeing the large expanse of floor (over 1000 square feet) that I planned to screed (c.f. discussion here a couple of weeks ago Laying Smooth Concrete Floor), he reckoned I would be much better off laying something called Celotex and fitting tongue and groove 2.5cm hardwood sheets over that.
Sounds much more manageable, although I know from experience that those huge, thick sheets of hardwood are monsters to lift and carry around! So not looking forward to that aspect.
Anyone done anything like this? What kind of Celotex would be the best to use under hardwood? I imagined Celotex would be just be of one type, like Sellotape, but there seem to be literally dozens of Celotex products!
