Condensation formation on the room side surface

The room air is able to absorb significant amounts of moisture depending on the temperature. As soon as the temperature drops below the dew point on cold surfaces, some of the moisture from the room air can precipitate there as condensate. If the outside air is colder than the room air, the room-side surface of insulating glass is always colder than the room air. The lower the U-value or k-value of an insulating glass, the warmer is its room-side surface under the same conditions, and the rarer condensate would be there. An important factor for the formation of condensate on cold surfaces is also the degree of saturation of the room air with moisture (bathrooms, kitchens, bedrooms). The most important measure for the regulation of the air humidity is the targeted ventilation of the respective rooms. The heat transfer is increased in all insulating glass in the edge region. This can be seen by the formation of condensate on the room side in the edge area.
