Victorian house, Attic room (original as far as we can tell) plaster is falling off the attic room.
Room has walls up to about 1.8m then follows the slope of the roof with a section in the middle that is flat. Room runs from party wall to gable end.
Floor has been insulated with rockwool and hardboard loft flooring has been laid.
The eaves are accessible through hatch doors, no insulation behind the existing plasterboard walls. Hardboard floors are in place in the eaves as well again with rockwool insulation underneath/protruding everywhere. The eaves are only used to store old boxes, suit cases and such.
This kind of shape

Walls of the room have been plaster boarded and are in decent condition. Plaster is falling off the ceiling (old lath and plaster) revealing 3x2 rafters and the felt membrane under the slate tiles. There's a couple of Velux fitted (north facing) so it has decent daylight.
During the winter the room gets stupid cold, we are planning on getting a radiator fitted which will help with that. But currently the room is unusable in the heat. So I'm hoping the insulation will help with that.
As I am re-plastering the ceiling and sloping sections I was intending to put some minimal insulation into the rafters (25mm polystyrene ?) then some insulated plasterboard (50mm ?) onto the sloping roof and flat roof section (can probably increase the polystyrene insulation on the flat "ceiling" section) I was also going to fit some insulation (75mm??) into the open stud behind the vertical plasterboard walls. Might have to staple some foil blanket to the hatch doors
Not sure what kind of insulation to fit and or if I am fitting stuff that is thick enough. So any advice would be appreciated? Am just at the stripping out stage, got to rip all the old plaster off this weekend or next.
