LITHOCELL® Composite Stone – TUF

Description of the product

TUF is a sandwich panel with a cosmetic finish consisting of a layer of Tufite (2 mm). It has an aluminium honeycomb core and galvanized steel sheet skins. It is obtained by applying a mixture of tuff stone powder and resins to a panel without finish such as the RAWCELL® Metal panel. Main fields of application: construction (external cladding of buildings).

Layers

1) INTERNAL CORE aluminium honeycomb (Starcell production) aluminium alloy: 3000 series density: 29 - 40 - 56 - 65 - 80 kg/m³ cell diameter: 6.35 mm (standard); 10 - 12.7 - 19 mm (on request)

2) ADHESIVE thermoplastic or polyurethane 3) EXTERNAL SKINS raw or primed galvanized steel sheet skin thicknesses: 0.3 - 0.5 - 0.6 mm (standard) 0.8 - 1.0 mm (on request) 4) FINISHING layer of Tufite (reconstituted tuff stone) thickness: 2 mm

PROPERTIES
  • Very high resistance to bending, shear and tensile stress.
  • Excellent dimensional stability, also in terms of flatness over time.
  • Very good compressive strength (due to aluminium honeycomb).
  • Excellent ratio between mechanical performance (high) and weight (content).
  • Excellent weather resistance.
  • Ideal for outdoor applications due to its excellent resistance to aggressive weather.
  • Ease of machining with manual or CNC equipment suitable for machining steel.
  • Wide operating temperature range.
  • Excellent fire resistance and low emission of toxic fumes.
FIELDS OF APPLICATION
Typical applications of LITHOCELL® Composite Stone - TUF are mainly for building façades.
STORAGE
The LITHOCELL® Composite Stone - TUF 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.
