Strategies include incorporating breathable membranes, ensuring adequate ventilation, and designing assemblies to maintain vapor flow continuity.</li><li>The NCC’s Part F6 Condensation Management outlines best practices to address this issue, emphasizing the importance of material selection and system design.</li><li>The issue affects both walls and ceilings.</li></ul> | %% DATAVIEW_PUBLISHER: end %%
