Default insulating draughty cavity under ground floor boards?

You ****ing well do.


Yeah, that was a bit daft.

Don't block the vents, unless you want the whole floor structure to
slowly rot away. The ideal thing t do is lift floorboards, fit
insulation between joists, add a VB over the top and re-lay the
boards. The not so ideal thing is to jsut rely on underlay to stop
drafts and not have insulation - but it sounds like now is as good a
time as any to insulate it.
