§ Column 4 and 5 outputs are subjective, for two reasons: a) the location of insulation materials are unknown/undeclared, and b) the presence or absence of a moisture barrier is unknown/undeclared. The risk values in columns 4 and 5 simply give the likelihood that condensation can occur either on a surface (building material or moisture barrier) or equally within an insulation layer. It does not indicate that fungus is necessarily inside the cavity, either in the present or the future, but it may indicate that the outcome of this cavity-analysis warrants further investigation, or warrants inspection of build records.
# Floor cavity excludes Slab-on-Grade.
^ Signifies Potential Fungal Risk in the cavity due to the possibility of external air leaking into the cavity. This is a putative risk only. Air leakage has not been tested for this report, rather the column signifies that air which may carry humidity has the potential to transport that humidity into a cavity. Such potential risk is affected by the temperature differential between outside and inside. If the risk seems to be of concern, refer to building records for clarification of the respective airtightness of the internal and external walls of this cavity, or alternatively get the airtightness tested.

When interpreting the outputs above comprising Risk Levels and Moisture Contents and using the tables below as a guide, any orange or red hues should act as a flag that may warrant some degree of investigation or cross checking. Frequently, an outcome of mixed color-indicators may be obtained for a particular surface, in these cases the presence of any orange or red hues is still a flag for further investigation. Green and yellow indicators come with caveats, such that while they are generally optimistic, other factors at the site may need to be taken into account on a case by case basis.
