While mix design and production technique can affect GFRC weight, a typical GFRC mix design will be 125-130 lbs per cubic foot. This equates to 7-8 lbs/ft2 at ¾” thick and 10-11 lbs/ft2 at 1” thick. Panelized GFRC, incorporating a steel stud frame, can weigh 10-25 lbs/ft2, depending on frame configuration.
