slabbing of walls or ceiling

I am planning to slab both the walls and ceiling of new build

Which should be slabbed first ?

using 50mm insulated slab on walls and a 35mm insulated slab on ceiling

Any advise on same !!!

Any job I was on Ceiling was always done first.

Its normal for the ceilings to be done first, but you have less thermal bridging if you do it the other way around.

thanks guys

thats cool
