VIC_Weight of laminated glass

Design professionals, wall system manufacturers, and construction managers often need the weight of materials for engineering and construction site considerations.  The tables below provide approximate weights of interlayer used in laminated architectural flat glass by North American manufacturers:

To calculate the approximate weight of a laminated product, add the weight of the interlayer thickness from Table 1 to the weights of the inner and outer lites of glass from Table 2. 

For example:

for laminated glass with thickness : 6,38mm ( 3mm glass+ 0.38mm PVB +3mm glass)

add = 7,6 + 0,4 + 7,6 = 15,6 (kg/m2)
