Moisture problems more often happen inside walls in cold climates because the interior drywall is typically too warm to pull the water vapor out of the air. The humid, indoor air has to find the exterior sheathing to find a cold enough surface to get into the materials.
How do you fix condensation on interior walls?
The more water vapor is in the air, the less cold the walls have to be for condensation to start showing up. So, to eliminate the problem, you can either block some of the outflow of heat through the walls by adding more insulation, or your can reduce the amount of water vapor in the air.
