What This Calculator Helps Check

VitraLab helps review laminated structural glass using pane dimensions, glass thickness, interlayer build-up, support condition, and applied load inputs.

Inputs Required

Enter the glass width and height, laminated pane build-up, support condition, load values, serviceability limits, and any project-specific National Annex values.

Calculation Method

EN 16612 Calculation

The calculator reports ultimate limit state stress separately from serviceability deflection, so the governing result for each limit state can be reviewed directly.

Stress and Deflection Output

Review ULS stress, SLS deflection, utilization, governing load effects, and pass/fail output so the laminated glass build-up can be assessed clearly.

Laminated Build-Up Review

Use the pane build-up fields to compare common laminated glass configurations such as two glass plies with an interlayer and to understand how thickness affects results.

The result can support early design and engineering review, but the final decision must also consider the full specification, supports, fixing system and local requirements.
