Which statement is NOT true regarding the formation of condensation?

The statement that curtains or drapes help prevent condensation on glass is not true. In fact, while curtains and drapes can provide some insulation, they may actually trap heat and moisture close to the glass surface. This can create an environment conducive to condensation, particularly if the air does not circulate effectively.

Understanding condensation is essential for a glazing contractor, as it relates to the performance and longevity of glazing materials. Condensation occurs when warm, moist air comes into contact with a cooler surface, leading to the moisture in the air condensing into liquid water. Factors such as temperature drops and high humidity levels directly contribute to this process. While ventilation and managing humidity can effectively reduce the likelihood of condensation, the role of curtains or drapes is more complex. Therefore, the assertion that they help prevent condensation does not hold true in many cases.
