  • Patent number: 4704831
    Abstract: A facade wall with a loadbearing skeleton of vertical posts and cross members inserted between the posts and connected at right angles thereto, which together form skeleton panels, provided with a seal, for receiving one plate element each, the post profile comprising in cross-section a room-side box profile portion and a weather-side head profile portion of smaller width and having on either side of the head profile a vertically extending seal retaining groove in the weather-side box profile surface. Lower and upper seal retaining grooves are provided in the cross member on the weather side. The cross member profile comprises a box profile portion and a head profile portion, which is arranged between the two horizontal seal retaining grooves and has horizontal seal retaining grooves in its upper and lower sides, each of which grooves is aligned with a vertical seal retaining groove in an associated side surface of the post profile head profile portion.
