What is one effective strategy to eliminate condensation on interior surfaces?

Increasing wall insulation is an effective strategy to eliminate condensation on interior surfaces because it helps to regulate the temperature differential between the interior and exterior surfaces. When walls are better insulated, the interior surface temperature stays warmer, reducing the likelihood of moisture condensing on cooler surfaces.

Condensation occurs when warm, moist air comes into contact with surfaces that are cooler than the dew point of that air. By increasing insulation, the conductive heat loss through the walls is minimized, allowing the interior surfaces to maintain a temperature above the dew point. This is particularly important in climates where there are significant temperature fluctuations, as well as in areas with high humidity.

Other strategies like installing air conditioning can help manage indoor humidity but wouldn't directly address the thermal performance of the walls, which is crucial to preventing condensation. Skylights might introduce more humidity and temperature challenges, while reducing window sizes typically results in less daylight and could create a less favorable living environment. Hence, enhancing wall insulation remains a direct method to combat condensation effectively.
