So, how much does each panel weigh?...
Well... the density of glass varies widely, but an approximate average is 2.5g/cm3.
Using the measurements of 32 ft x 10 ft x 2 inches, the volume of each panel is approximately 1,510,231.818 cm3.
At 2.5g/cm3, this equals approximately 604,092.727 grams, or 604.09 kg or 1,330.60 lbs.
(Check my math... sounds about right to me).
Don't drop that sucker on your toe!
You divided by 2.5 instead of multiplying. The correct weight is 3.775 kg or 8328 pounds. One square foot at that thickness is 26 pounds.
