Condensation occurs when moist air comes into contact with cooler surfaces, like glass in a conservatory. Effective insulation helps to maintain a more consistent temperature inside the conservatory, reducing the temperature difference between the air and the surfaces. This, in turn, can lessen the likelihood of condensation forming.
However, adequate ventilation is also crucial in managing condensation by reducing indoor humidity levels. Combining insulation with proper ventilation offers the best approach to stop condensation in a conservatory.
