In natural convection fluid motion results from the hot atoms in the fluid where the hot atoms move upwards toward the cooler atoms in the air the fluid moves under the influence of gravity. So for example for air if you are able to eliminate these convective currents or lock the air into place then its practically an isolator. This chart gives the thermal conductivity of.

Near the surface where the fluid velocity is low diffusion or random molecular motion dominates.

K is the thermal conductivity of the body. Poor conductors are called insulators. K is the thermal conductivity of the body. Eventually youll get small circle or several flow of air that transports the heat from the bottom to the top and thoroughly mixes the air throughout the room.
