Insulation on top of loft boards - good idea?

Hi,

I currently have 270mm of glass fibre insulation in the loft of the house I just moved to.

I want to board it up for storage but I have a long term plan to get someone in to do a proper job and convert it to a habitable room.

Is removing some of the insulation to exposed the joists, laying structural chipboard and then replacing insulation on top of the chipboard in areas I don't need a sensible option?

I know there are loft legs available but I don't want to spend a load of money on them (or put loads of holes in the joists) when they won't be needed in the long run?

Thanks for the help,

Ben

    Why not just leave it alone in areas you wont need for storage?

    Remove the glass fibre insulation and replace with PIR board. Put the loft boards on top of the PIR board, you'll probably get about 75mm of the stuff to fit, which is about the same as 20cm of glass fibre insulation. When you convert the loft the PIR board can be left in place.
