Bill is thinking about installing a tongue & groove ceiling at his cabin, but Tessa and Reuben give his idea no love.

Tessa shares that air leakage and moisture getting into the attic can be prevented in multiple ways. However, the climate zone, amount of air leakage, humidity levels in the house, size of the attic space, and the volume of air in the attic are major factors in how the ceiling will perform.. One way to test the efficiency is by de-pressurizing the house and using an infrared camera to trace the air pathways back to the gaps. While Reuben shares that condensation issues are common among tongue and groove ceiling installations.

Reuben talks about some challenges in the use of fiberglass insulation and suggests the use of drywall for a consistent air barrier. They also talk about the use of spray foam, polyethylene sheeting, rockwool insulation, and guardrails.
