How condensation moisture forms

In this article we will explain how condensation fluid is formed, what its symptoms are. You can ask for more information about this moisture problem at the bottom of the article.

Air naturally always contains a certain amount of moisture. The higher the air temperature, the higher the humidity can be. As a result, the air in homes can be more humid than the air outside.

Because of the vapour pressure difference there will always be a moisture transport from the inside to the outside. There is a possibility that the moist air will condense along the way when it meets cold surfaces. Think of cold walls, cold windows or in cold rooms such as cellars or crawl spaces.

Condensation occurs when the partial vapour pressure reaches saturation pressure when the temperature drops. We call this temperature the dew point. If that dew point is on the surface (like glass) then there is superficial condensation. Surface condensation is determined by the surface temperature and the vapour pressure inside.

Condensation moisture control

Condensation is a natural phenomenon associated with the humidity of certain living areas (e.g. bathrooms, cellars, kitchens, living spaces) and with external factors such as the season and the outside temperature.

Aeration is usually the first factor to be considered to treat condensation problems. Read more about all ventilation solutions to combat condensation problems here.
