I could be wrong, but I doubt there is anything to be chalked between the compartments and the living area. Those compartments are separate boxes. What you're probably feeling is the cooler air in the compartments actually falling out as warmer air enters. It may be cooler because of the compartment proximity to the floor of the living space, but not actually coming from the living space.

Well... that's my 2 cents worth.
