Precast Wall Panel Weight Calculator

Total Panel Weight is, at this calculator's default inputs (no reveals, no insulation, no openings), a pure product of Panel Height, Panel Width, Panel Thickness, and Concrete Unit Weight -- concrete volume equals height times width times thickness, and weight equals volume times unit weight, plus a flat 6% reinforcement allowance. Because all four quantities enter as a straight multiplicative product with no other input, they carry identical proportional influence on Total Panel Weight and Stripping Force at those defaults -- a 10% increase in any single one of the four (with the other three held fixed) raises both outputs by essentially the same 10% swing, measured at this calculator's default panel. Insulation Thickness changes that picture for sandwich panels: once it's greater than zero, the concrete-only thickness used for weight is Panel Thickness minus Insulation Thickness (clamped to a 3" minimum), so on a thin sandwich panel where insulation already consumes most of the declared thickness, further increases to Panel Thickness can stop moving Total Panel Weight at all because the concrete layer is already sitting at its 3" floor.

Window/Door Openings and Reveal Coverage both subtract material rather than add it, so they move Total Panel Weight in the opposite direction from every other input. Stripping Force is simply Total Panel Weight multiplied by a flat 1.5x safety factor, so anything that moves one moves the other by the identical percentage.
