Question: Which strategy is most effective for controlling moisture accumulation within a wall cavity due to interior humidity in a cold climate?
Answer options:
- Installing a permeable air barrier on the exterior side. ✅ Placing a vapour-impermeable barrier on the warm-in-winter side of the insulation.
- Ensuring all exterior sheathing joints are sealed with waterproof tape.
- Using a high-density fibreglass batt insulation throughout the wall.
Correct answer: Placing a vapour-impermeable barrier on the warm-in-winter side of the insulation.
Explanation: Placing a vapour-impermeable barrier (vapour barrier) on the warm side of the insulation in a cold climate restricts the movement of moist interior air into the colder wall cavity, thereby preventing condensation and moisture accumulation.
