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.
1 Moisture Barrier-Moisture barriers (like Tyvek, for example) are properly installed on the exterior of a frame wall, directly on top of the sheathing, and under the siding. 2  Moisture barriers help prevent water from entering the wall cavity.here is sometimes a concern in regards to installing a vapor barrier with a masonry veneer wall. This concern is related to the situation where, on a sunny day, water that is trapped in the brick may have a tendency to migrate into the wall system.
