A transportation barrier is a natural barrier like mountains, rivers, oceans, etc that blocks or slows the way of transportation.
Vapor barriers are materials used to slow or reduce the movement of water vapor through a material (water vapor is also transported by air leakage but this can be resolved by installing an air barrier).Vapor barrier materials are installed on the warm side of the insulation in a building assembly.ir barriers are not to be confused with vapor barriers or water resistive barriers. Each barrier have a different function to perform in a building assembly.
