Summary

Calculated penetration scales using the fixed properties of the wooden and concrete wall example. Based on Van Rossum (2027), §5.2.

Original illustration for Thermal diffusivity, level 3 Advanced.

Source basis: Van Rossum (2027), §5.2, wooden/concrete wall example; arithmetic in calculations.json.
Alt text: Square-root curves reach approximately 24 mm for wood and 54 mm for concrete after 3600 s.
Accuracy notes: Do not interpret d as a sharp temperature boundary, charring depth or fire-resistance limit. Use one consistent property set for each material.
