PROPERTIES
  • Excellent fire resistance and low emission of toxic fumes.
  • Excellent resistance to shear and bending forces.
  • Excellent dimensional stability, also in terms of flatness over time.
  • Very good compressive strength (due to aluminium honeycomb).
  • High mechanical performance, compared to the remarkable lightness of the panel.
  • Excellent weather resistance.
  • Wide operating temperature range.
  • Ease of machining with manual or CNC equipment.
FIELDS OF APPLICATION
The RAWCELL® FIBER - PGF panel is normally used in naval applications where the use of fire/smoke certified materials is mandatory; in particular, the panel is extensively being requested for internal use in the sector of motor yachts and large shipbuilding (furniture, structural bulkheads, support for lightened stone, etc.) where its excellent performance is increasingly appreciated and where, due to weight or compatibility with particular finishes (marble, granite, etc.), metal support materials cannot be used.
STORAGE
The RAWCELL® Fiber - PGF panel is a product in the “semi-finished products” category and therefore is 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 their edges.
