That's certainly an idea, Dave. Do you know how much lighter they
actually are?

Regrettably no, but try picking up an 8 x 4 piece of chip board and then
a bundle of floor boards that will span 4 foot, even if they are longer.
Anyone else on here that can be more definitive?

From memory the density of chipboard is about 680 kg/m^3 whereas spruce
is about 600 kg/m^3.

Gordon Bennet, my sums must be wrong, that works out at around half a ton.
Sounds like a re-think.

Exactly the figures I see. Most people "remember" chipboard in terms of
worksurfaces for kitchens, which are very thick and heavy. There isn't that
much difference in the density in reality. Floorboards can work thinner than
you would with chipboard though, so one might save a bit there.
