very thin insulation

Note that real-world performance for multi-foil is nothing like as good as laboratory results. Have a look on the green building forum.

^^^^^^ wot he said. "Laboratory tests" are usually devised to show the product in a good light, often by a British Standards committee packed with "experts" who have a financial interest in the product. The real-life performance is often far short of that which the lab tests suggest.

There is stuff called sempatap which is suitable for insulating solid wall flats.

Yellow Fang, there's a green-eyed yellow idol to the north of Katmandu but that's no good for insulating flat roofs either [though it's not as expensive as sempatap.]

How high is your ceiling ?

50mm of a polyurethane type foam like Kingspan, plasterboarded and skimmed would be an excellent solution, however don't do it if it will make your ceiling less than 2.3m , rooms rapidly start to become claustrophobic under that height.

+1 Insulated plasterboard on dabs or adhesive would be my suggestion too, but not if it dropped the ceiling height below 2.3m. Same stuff on the walls. Before you do that though - get someone i.e. Kingspan themselves, to do condensation risk calcs. For that they would need to know the exact make up of the roof and walls.

Never stick ceiling plasterboard with adhesive aberal... always screw fix to joists.

Expensive... but if that's the only space you've got available it works...
