Interstitial condensation is condensation occurring within or between the layers of the building envelope. The migration of water vapour through the building envelope by diffusion or air leakage brings the moisture into contact with concealed surfaces. This gives rise to serious deterioration of materials. The allowable humidity level to avoid interstitial condensation is much lower than that for surface condensation.

Interstitial condensation occurs inside a material.
Vapour can pass through porous building materials. If the dew point temperature
occurs within that material then, as with surface condensation, the vapour will
condense.

i did what you should do and entered a search and found basically that interstitial condensation is caused by the warm air within,e.g a building being saturated with moisture coming into contact with a much colder surface, inside surface of external wall therefore causing condensation
