Early life and education[edit] Rice was born in Washington, D.C., to Emmett J. Rice (1919â2011), Cornell University economics professor and the second black governor of the Federal Reserve System, and education policy scholar Lois Fitt (nÃ©e Dickson), currently at the Brookings Institution. Her maternal grandparents were Jamaican.
A vapour barrier (or vapour barrier) is any material used for damp proofing, typically a plastic or foil sheet, that resists diffusion of moisture through wall, ceiling and floor assemblies of buildings to prevent interstitial condensation and of packaging.he function of a vapor barrier is to retard the migration of water vapor, which are not typically intended to retard the migration of air. This is the function of air barriers.
The job of a vapour barrier is to prevent vapour diffusion, and the job of an air barrier is to stop air leakage through differences in air pressure.o think of a windbreaker as an air barrier, and a raincoat as a vapour barrier. That is about as far as I can stretch the human to house analogy, hope it helps. Related topics: 1  Vapour barrier paint: faster, cheaper and better than polyethylene.
