POLYLAYER, MULTIFUNCTION ENVELOPE

There is represented an envelope usable as bearing and/or insulating componentry, comprising internal bearing layer 1 and external hydro- and/or heat-insulating layer 4 covered with facing componentry 2 from outside. Bearing layer has zig-zag, broken or nosing configuration at cross-section, and is executed as a cast between fixed falsework shields of concrete, collecting channeled concrete componentry or masonry; hydro- and/or heat-insulating layer is allocated wholly or partly in a space between bearing layer and facing componentry, wherein unfilled spaces are appropriated for usage as ventilating or leak channels.
