DEW POINT AND RH EXPLAINED
When we’re talking about condensation it makes logical sense to equate those water droplets with the amount of moisture in the air at any given time, or the?relative humidity. However when we’re talking about building science and interstitial condensation (condensation in between two sides e.g. a wall cavity), what we actually need to talk about is the?dew point. So what’s the difference?
Relative humidity?is the amount of moisture?present in the air relative to the current maximum moisture capacity of that air and it varies depending on the air temperature.
Dew point?is the temperature at which the relative humidity in the air will turn into water droplets... To read on click here
