It does, but the idea of this material is to bounce radiant heat back

Warm air rises (natural convection) because it is less dense than cold
air.
Heat is transferred by conduction, convection & radiation. This
reflects radiated heat back into the occupied space, reducing the
radiant heat loss.

Well strictly speaking, cold air sinks, and enough that it'll push warm
air upwards out of the way...
True of course for any homogeneous gas or liquid.

In suspended floors it is best to use high density insulation slabs to
prevent sound and heat travelling through the floor- it kills two birds with
one stone.
