Explain how the “robustness” feature of resilience should be applied to prepare for or respond to a natural disaster.
Weather barriers (aka air barriers) differ from vapor barriers in that: Weather barriers are breathable and go on the outside of wall sheathing, while vapor barriers are not permeable and go on the interior side of wall insulation. Weather barriers are not breathable and go on the outside of wall...
