Abstract
The present disclosure is directed to a flood barrier designed for the dry-flood proofing of door and window openings in a building. The flood barrier includes a rigid frame, preferably formed of metal extrusions. To this frame are clamped a water-impervious barrier and a sacrificial bladder to protect the water-impervious barrier from impacts by wind- or water-borne, debris and impacts. A number of webbings may be provided on the side of the water-impervious barrier opposite the sacrificial bladder to further support the water barrier layer. Sealing gaskets are provided on the rigid frame where the frame contacts the building, or in case of a door opening, also the floor. The sacrificial bladder permits water to accumulate between the sacrificial bladder and the water-impervious layer thereby utilizing the non-compressible nature of the water to attenuate the impacting force.
