sheet rock weight

[oreo123]

Does anyone know the weight of half inch blueboard - for 8 footers? We are about to boom in 90 sheets into a 3 room loft, plus 25 bags of 50 pound plaster. Of course we will split the load up - but were wondering the real weight of the load. I seem to remember 62 pounds but cannot remember if it was for half or three quarter rock.

TIA.

Off the cuff I would say it's around 2lbs / sf. 64 lbs / sheet, and 5760 lbs for 90 sheets.
