Underfloor Insulation

Hi all,
In the interests of saving energy in the long term, we have opted for underfloor insulation throughout our ground floor (suspended timber floor). Insulation is mineral wool on netting suspended between the joists.
However... post-install, and we're still getting draughts coming up through the sides of the carpets/where the skirting meets the floorboards. The installer suggested it was coming from behind the skirting, and therefore probably from the wall cavity rather than under the floor. Admittedly the draught is stronger where there are bigger gaps between the skirting and the floorboards, but I don't know enough about housebuilding to know if this is correct?
The reason I'm a bit hesitant to take this at face value is that we're also getting a significant draught coming from another corner of the room that does not touch any external walls...
Ultimately, I'm trying to guage if it is reasonable for us to expect no draughts from around the edges of the room after we've had underfloor insulation installed? Just feeling a bit disheartened that we still have cold draughts coming through, after spending a lot of money on something we thought would fix it!

What you need to do is seal off any gaps between floors and skirtings, if these are large you may need to use something solid. There was a thread about what to use, on here, a while back
