Insulation of a Bay Window box

Seve OB

I hope someone can help me please. Our front bedroom is west facing and overlooking a green area so no houses to block any wind. The room gets unbelievably cold compared to the rest of the house.





When I put my hand under the lip, the plasterboard is not secured to the wooden seat. I can actually lift up the seat and feel a draught coming in





So with the draught coming in I figured i needed to insulate it, but when I cut a small hole in it, I see there seems to be plenty of rockwool in there already.







Anyone got any ideas on what I can do? I thougth about pumping in expanding foam but with all the rockwool in there already, I dont see the benefit.

Another thought is to raise the seat with a layer of Kingspan insulation board - - would this do any good?

Also seems to be quite cold above the window so think I need to do something similar here?

Hope someone can help

Thanks
