Intent
Intent 1: 
To limit the probability of inadequate thermal performance, which could lead to accelerated deterioration or compromised thermal resistance of the insulation, which could lead to excessively low temperatures of interior surfaces or within assemblies.
This is to limit the probability of condensation, which could lead to deterioration, which could lead to compromised structural integrity of assemblies acting as environmental separators, which could lead to harm to persons.
