PROPERTIES
  • Excellent resistance to effort and bending stresses.
  • Excellent dimensional stability, also in terms of flatness over time;
  • Excellent compressive strength (due to the aluminium honeycomb).
  • High mechanical performance, compared to the remarkable lightness of the panel.
  • Excellent resistance to atmospheric agents with a wide range of operating temperatures.
  • Excellent impermeability to liquids (No Water) and ease of working with manual or CNC equipment.
  • High surface roughness which greatly promotes the bonding of stone finishes.
FIELDS OF APPLICATION
Typical applications of the RAWCELL® FIBER - PGA-NW are in the marble, stone and ceramic markets; the panel is often used for civil engineering applications both indoors and outdoors (including application in ventilated façades); it is supplied in standard or custom sizes to suit all needs.
STORAGE
RAWCELL® FIBER – PGA-NW panels belong to the "semi-finished" category and therefore subject to further processing; we recommend storing the panels horizontally in a closed and dry environment, possibly away from heat sources and to support them along the perimeter.
