Timber EMC & Mold Risk Calculator

Uses ambient temperature and relative humidity to estimate the Equilibrium Moisture Content (EMC) of structural timber. EMC below 16% is safe, 16-18% warrants monitoring, 18-20% is a high mold risk, and above 20% risks active wood-decay fungi.



Psychrometric Drying & VPD Calculator

Uses dry-bulb temperature, wet-bulb temperature, and relative humidity to estimate specific humidity (grains per pound) and the vapor pressure differential that drives structural drying. A low differential means standard dehumidifiers stall — LGR or desiccant units are required.
