Would there be a water damage inside, at the absence of any rain intrusion or plumbing leaks? Microbial growth? We found the answer in many cases is yes.
These hygro-thermal analyses are performed on facades of buildings in design stages, in order to assess the moisture behavior of very simple assemblies. Most typically performed to assess the need and location of vapor retarding layers.
We also perform a long-term hygrothermal monitoring of assemblies in the field, in order to identify sources of moisture damage after the possibility of leakage has been ruled out.
