What should the vapor barrier of insulation face for optimal efficiency?a) The exterior of the buildingb) The interior of the buildingc) Upward, toward the ceilingd) Downward, toward the floor
Solution
The vapor barrier of insulation should face the interior of the building for optimal efficiency. This is because the main purpose of a vapor barrier is to prevent moisture from getting into the insulation, which can reduce its effectiveness. In most climates, the interior of a building is more likely to be humid than the exterior, so placing the vapor barrier on the interior side of the insulation helps to keep moisture out.
