Laminate Flooring Over Finished Concrete

Hi everyone

I live in a studio loft with concrete floors that already have a basic painted finish.
i'm planning laminate floors and have a few questions

firstly, a few things to consider:
all walls are concrete
no windows
just skylights
no insulation on the roof
so in the winter ambient temperature is 55-60 degrees
its an open warehouse space,
15ft ceilings means this place gets cold
im on a budget

i do not own this space and so do not planning on keeping using them for 2-3 years, so quality or durability is not the highest priority

i've been told that for laminate over concrete, a 6 mil plastic moisture barrier is required for concrete, however, does this apply for concrete that is already finish / painted?

in terms of thermal benefit
does 8mil really make a difference between 10mil or 12 mil?

some of the 12mil floors come already with a pre-glued sublayer.... i'm not sure if this would be sufficient or would it still be wise to add more ?

whats the minimum sublayer that i would need?

whats the most optimal sublayer if trying to warm the floors as much as possible?

thanks for any and all suggestions

Need to go by the manufactures instructions.
It varies from brand to brand.
Any hard flooring like that is going to feel cold under foot.
