Vaulted tongue and groove ceilings are a beautiful architectural feature, but they are often prone to moisture accumulation and ice damming due to significant air leakage. This video breaks down why traditional assemblies frequently fail when insulation is added and explains the critical difference between vapor diffusion and air infiltration. Finally, we demonstrate the best construction methods—including dedicated air barriers and proper ventilation—to build a durable, worry-free ceiling assembly that lasts.
