What This Calculator Helps Estimate
VitraLab helps estimate glass weight from pane dimensions, glass thickness, and build-up so the dead load can be reviewed alongside structural glass checks.
Inputs Required
Enter pane width, pane height, glass thickness, and the glass build-up type. Laminated glass weight should include the relevant glass plies and interlayer thickness where applicable.
Glass Weight Formula
A common estimate is based on area multiplied by glass thickness and glass density, often approximated as 2.5 kg per square metre per millimetre of glass thickness.
Laminated Glass Weight
For laminated glass, the total weight depends on each glass ply and the interlayer. This makes build-up review important when comparing alternatives.
Why Weight Matters
Glass weight affects handling, fixing design, frame loads, bracket reactions, transport, installation planning, and project coordination.
Use With Design Checks
Open the calculator to review glass weight together with ULS stress checks, SLS deflection checks, load cases, and support assumptions.
