Concealed condensation occurs inside an envelope assembly during a heating season if
A)the R- value of the assembly is high.
B)the R- value of the assembly is low.
C)the interior vapor can permeate into the assembly but cannot exit it.
D)A and B.
E)A and C.

Question

Quizplus · Accepted Answer

Concealed condensation occurs when interior vapor is able to permeate into the assembly but cannot exit it, leading to the formation of condensation. The R-value of the assembly does not necessarily play a role in this process. In fact, high R-values can actually increase the likelihood of concealed condensation by reducing the ability of moisture to escape the assembly. Therefore, the best choice is E, which includes option C about interior vapor permeation and option A about high R-values being incorrect.
