  • Generic building walls are mainly claimed by their own weight and are not integrated into the static concept of a building. However, they must absorb forces acting on their surface and introduce them into the adjacent supporting components. Deformations of the adjacent components must not lead to constrained stresses in the non-load-bearing building walls, so that these Building walls are separated by movement joints of the adjacent components.
  • Generic building walls must meet certain requirements in terms of sound, heat and fire protection.
