ABSTRACT:
A multi-layer barrier for insulation blocking an opening or passage of a building and for providing ventilation to or within a building. A plurality of inflated hollow membrane cube-like structures are formed adjacent to one another, which traverse a longitudinal width of the opening or passage. The hollow membrane cube-like structures are formed from generally rectangular sheets having two long parallel edges, two parallel short edges and a floor having one or more orifices in the forming floor of each non-bottom sheet between membranes, for air connection between membrane structures to be changed from an inflated and a deflated state.
