Floor Isoboard to Keep HEAT Out - Is It a Good Idea or DISASTER?

Hi

I've been reading that in cold climates, people recommend using Isoboard in the concrete flooring to keep the heat IN the house.

I've also read that for cold rooms, people recommend using it to keep the cold in.

We're building a thatch house and we live in a hot area (near Kruger, where it's often 35 to 42 deg C).

I want to know if putting isoboard in the floor concrete a good idea?

Will it keep the heat out?

OR....will it trap the heat in the house!!!

Does anyone have any experience with heat transfer in the flooring to keep the outside heat out and the inside cool?
