Ceramic pieces formed by a masonry (brickwork) sheet separated from the facade by a ventilation chamber (cavity), allowing the outer sheet to rest on the facade and the formation of the perimeters of the hollows (apertures), consisting of five pieces: joining impost (springing line, fascia) between sheets, normal or ventilated, which allows the removal of moisture; lintel (beam), a piece provided with through-pouring (casting) in order to form the upper part of the hollows, able to serve, in certain cases, as impost; embrasure (windowsill), with curved surface and weathering (wash) for closing the hollows at the bottom except at the corners where the so-called upright (jamb) piece is positioned, which allows the lateral brick and the shutter carpentry to be supported, guaranteeing leaktightness. All this advantageously replaces metal securing elements which are currently used, both in terms of differential movements and in terms of a reduction in movements derived from thermal bridges. <IMAGE>
