Intent

Intent 1:

To limit the probability of excessive water vapour diffusion, where the intended use of the interior space will result in high moisture generation, which could lead to condensation or water accumulation within the assembly.

This is to limit the probability of deterioration, which could lead to compromised structural integrity of the assembly, or assemblies supported or protected by the environmental separator, which could lead to structural failure, which could lead to harm to persons.
