I need to apply some insulation to a concrete ceiling the -topside being exposed to open air, hence its cold in winter on the inside!. I have limited headroom so can only go to max of 45mm inc plasterboard. Which option is best? The room will be heated and correctly ventilated, so I just need to stop the cold air against the ceiling causing the cold, as the walls are insulated.

Spray foam requires studding or furring out space. The Thermoboard can be directly applied to ceiling if smmoth enough, thus preserving headroom. Also spray foam is more expensive & requires pro application. The other is DIY.
