Insulating part of loft with bad access?

    Hi, I live in a dormer house. Been up into the loft space and have seen the main part of the loft (where you can stand up in) has had some yellow fiberglass insulation laid (not very thick o4 it has compressed over time, maybe 4") and then recently has been topped up with some nice thick pink fiberglass insulation. However, I shined a torch into the edges of the loft (where the ceiling would slope in the bedrooms) and they have not been topped up with new fiberglass insulation and its just yellow stuff again doesn't look very thick) trouble is in them spaces there is no way you would be able to get in there and top up the insulation, there's not enough space for a person to crawl in there. I'm even trying to fathom out how someone got in there in the first place and managed to insulate it.
    Anyway I doe think this is having an effect on the bedrooms which tend to be cold in the winter than they should be when heating goes of and hotter in the summer.
    I am thinking maybe the solution could be to get some bags of vermiculite and pouring it in that space, but then as I say there is no room for a person to get into that area, its too small. So what I want to ask is that is it possible that the vermiculite insulation can be somehow 'blown' into these spaces if that is possible? Also apart from vermiculite can you also buy polystyrene beads these days (I know they would have to be fire treated /fire resistant these days) thanks for any advice.

    Presuming your felt is the black non breathable type, a 50mm air gap is required between insulation and felt.

    Thanks, do you mean the felt under the roof tiles? If so, that felt is white and seems to be of a fabric type
