Thermal Hygrometry (Temperature-Humidity Analysis)
Measurement of temperature and relative humidity within building cavities to identify moisture sources and condensation risks.
How Thermal Hygrometry (Temperature-Humidity Analysis) Works
Thermal hygrometry is the science of measuring temperature and relative humidity in building cavities to assess moisture conditions and identify condensation risks. Using wireless data loggers placed inside wall cavities, ceiling spaces, and crawlspace areas, we monitor temperature and humidity over extended periods (typically 7-30 days). The data reveals whether a visible moisture issue is caused by condensation from high humidity or by an active leak. This distinction is critical for determining the appropriate remediation approach. Thermal hygrometry is particularly valuable in BC's coastal climate where high indoor humidity can cause condensation in cavities that mimics leak patterns.
Applications in BC
- Distinguishing condensation from active leaks
- Assessing attic and crawlspace moisture conditions
- Investigating chronic mould issues in buildings
