1. A stricture for an electric or hybrid vehicle, comprising:
a floor;
a battery tray secured beneath the floor; and
a compressed foam plate arranged between the battery tray and the floor,
wherein a surface of the foam plate comprises microscopic perforations configured for evacuating air contained in the foam when the foam plate is compressed and/or configured to avoid ingress of water into the foam, and
wherein a density of the microscopic perforations is between 2 and 10 of the microscopic perforations per mm2 of the surface of the foam plate.
