Ventilating space behind cladding to be a minimum of 20mm, or according to project design criteria, whichever is the greater.
Reveal joint width between panels can vary from 5mm to 25mm. Panel face nominal maximum 300mm. Panel length nominal maximum 4000mm.
Panel weight per lineal meter ≈2,95kgs, ≈9,5kg/m2.
Panels shall be secured back to supporting structure using fasteners made of grade A2 stainless steel, or A4 grade in severely corrosive environments. Supporting structure profiles (rails) to be perpendicular to panel orientation, have a face width not less than 40mm, and be installed true and plumb.
