Condensation Resistance Evaluation of a Double-Sliding Window System in Accordance with the Korean Design Standard for Preventing Condensation in Apartment Buildings (OR-16-C073)

Recently built residential apartment buildings have faced the issue of increased condensation risk caused by highly insulated and airtight building designs used to decrease building energy consumption. In particular, glazing systems have a high risk of condensation on the inside surface of building envelopes. Especially during cold winters in Korea, condensation in residential buildings damages the interior surfaces, leading to mold or mildew problems and causing discomfort of the building occupants. To eliminate condensation risks and secure the well-being of the occupants, the Korean Design Standard for Preventing Condensation was announced in 2014. Nonetheless, current glazing systems in the market cannot fulfill the strengthened design standards. Therefore, a high-performance glazing system that satisfies the new enhanced standard is needed. A brief comparison between the newly developed Korean Design Standard for Preventing Condensation and other international standards was performed.
