Methodology and scope

This tool calculates effective thickness for laminated glass under defined support, load, temperature and duration conditions. It is intended to support engineering judgement, not replace it.

Standard supported

EN 19100-2

Planned: ASTM E3491

Supported configurations

  • Laminated stacks
  • Multiple glass layers
  • Multiple support conditions
Modern building
Blurred view through floor-to-ceiling glass panels, with soft daylight and hints of greenery outside.

Notes and limits

  • Stress vs. deflection effective thickness differ (both shown)
  • Closest match flagged in results
  • Unsupported inputs blocked
