  • the present invention relates to building panels and in particular panels for the construction of roofing arrangements of structures, able to diffuse light coming from the outside within the structure.
  • the invention relates as well to a roofing arrangement implemented with one or more panels according to the invention.
  • one of the methods of implementing roofing arrangements is to use panels made of lightweight and cheap materials, such as for example thermoplastic materials.
  • panels made of polycarbonate, for example of honeycomb or compact type, methacrylate, PVC, etc. are used.

  • the panel according to the present invention applies particularly in the construction of roofing arrangements of structures inside which an optimal light diffusion through the panel is required.
  • Transparent panels are known that allow the light, for example sunlight outside the structure, to cross the panel and thus penetrate to the inside of the structure.
  • some panels known in the art have a satin finished surface, and in general a surface made opaque.
  • Such panels allow reducing the glare phenomenon and, in some instances, increasing the uniformity of light diffusion, for example with respect to a completely transparent surface panel in general lacking of a satin finished.
