B) The thermal Expansion of Viva sheets is (2.4mm/m/100) °C, so maintain proper distance between two panels for thermal stability of sheets. The distance calculation is :
Thermal expansion x sheet length (in meter) x Delta T (Temperature Variation) 2.4 x 3.66 x 0.3 (if Delta T is 30 ‘C) = 2.64 mm.
With this method we can calculate the thermal expansion of the particular length of sheets.
C) The stiffener & structure should be proper aligned for smooth finish on sheets. (Generally 4*4 Ft or as per recommended structure)
D) It is necessary to take into account the wind pressure at particular altitude and area.
E) To avoid colour variation for part order, batch printed on bottom of sheets must be provided during next order.
F) Take care of diagonal length of sheets during cutting or grooving to avoid the taper finish of panel block. The diagonal should not be more than 2mm.
G) Remove the protective film after installation as soon as possible as after long time more than 45 days it is difficult to remove protective film. Try to avoid remove the protective film below 10 °C.
H) Do not remove the protective film with jerk, remove it smoothly with equal pressure to avoid deflection and humps.
