Any way to improve this flooring job I did?

I got the boards from Woodies and they slot in together nicely, but it turns out that the insulation material (glass wool?) is so thick that the boards couldn't touch the wood underneath. So it's not solid at all now.

Do people normally change the insulation to something else when putting flooring down? Pic attached.

You will have to take up the flooring you put down. Won't take long as it looks like they were just trowing there.

Next step take up fibre glass and put it back down between the joists. I cannot tell from picture but it looks to be put on top of joists. Maybe I'm wrong but if it was just put on top of joists and not cut to size you will have to cut the fibre glass to fit between joists.

Thanks wotzgoingon, Ill see if I can adjust it so that they're exposed... Although the thickness/depth it seems to exceed that of the joists anyway so maybe the fibreglass is a problem.

From the direction of the trusses it has a top up layer of insulation laid ,I've seen plastic supports in B&Q for the job. http://www.diy.com/nav/build/insulation/loft-insulation/Diall-Loft-Storage-Stilts-12-Pack-11837507

Buy a few lengths of 2x2 and screw these down to your joist running in the opposite direction, then lay your flooring on top of these.

cheif kaiser, I actually can't get the 'okay' for that from the landlady which is why I went for the panels that click in together. Otherwise, nice suggestion.

You probably have 150mm between the joists and 150mm on top laid perpendicular? I would take up the top layer and replace with 100mm xps (extruded polystyrene) which is very solid and lay some chipboard on top of this. Alternatively you can buy xps with chipboard pre attached which slots easily together http://www.uvalue.ie/products/thermawalk/

Thanks kilcion. The property is a rental so while I was happy to spend EUR 30 on the boards I'd imagine re-insulating would put the costs into the hundreds. She probably wouldn't let me do that anyway since she said no to my idea of putting boards down until she found out I could take them away and leave the attic as I found it if I move out. But it's good to know as I'll probably want this if I ever buy a house.
