Definitions

  • the present invention concerns a cladding assembly and a method for cladding the walls of a building in order to insulate it, at least thermally, from the external environment.

  • the cladding assembly can be used in a residential or industrial building and/or in public facilities, such as hospitals or schools.
  • Cladding assemblies for cladding the walls of a building are known, which allow to insulate it, at least thermally, from the external environment.

  • the insulating panels are attached to the wall using screw anchors, and the subsequent finishing is done with mortar and fiberglass mesh, or other plastic materials.
  • Pre-finished cladding assemblies are also known, in which the insulating panels have smaller thicknesses than those used in insulation layer assemblies and, very often, are laid and attached only with cementitious adhesives without the use of screw anchors.
  • both the laying as well as the finishing have to be carried out in a very short time, since the insulating panel cannot remain exposed to the elements or to the UV rays of the sun for long.
  • both the skim coat as well as the finishing have to be completed in a single operation in order to prevent rings, stains and unevenness on the external surface.
  • cladding assemblies have also been used to clad a wall which provide the use of panels, or slats, of composite material, for example made of Wood Plastic Composite (WPC) or suchlike.
