Definitions

  • the present invention relates to a pack comprising an arrangement of insulating panels according to the preamble of claim 1, a method to manufacture such pack, a pallet comprising such pack and the use of such pack.
  • the façades of buildings are recurrently thermally and acoustically insulated by applying insulating elements externally to the structural elements.
  • the ETICS commonly comprise a layer of insulation elements (e.g. panels) arranged externally on the surface of a structural element (e.g. the façade), fastening devices, a rendering coating (e.g. mesh reinforced mortar) applied to the external surface of the insulation elements, and optionally a finishing layer (e.g. dyed mortar), acting as an aesthetic and/or protective layer for the outer surface of the system.
  • the insulation elements in these insulation systems are usually formed by panels made of fibrous insulating materials (glass wool, stone wool, or wood wool). These insulation elements are required to have high mechanical robustness and resistance against compression and tearing forces, particularly in the direction of the thickness of the insulation elements.
  • ETICS comprising insulation elements with layers of different rigidity have been described as advantageous.
  • a softer, more flexible layer is arranged closer to the structural element (internal layer), while a harder, more rigid layer is located further away from the structural element (external layer).
  • the harder layer serves as a resilient base withstanding mechanical stresses applied to the insulation element, while the softer layer reduces the weight of the insulation element, contributes to an improved thermal insulation capacity, and being more flexible, is capable of better adapting itself to contours and irregularities which might be present in the surface of the structural element.
  • Insulating panels are normally delivered to construction sites with a suitable protecting packaging in order to preserve their properties.
