IQRG Condensation Control Solutions for Heated Buildings in Moderately Cold and Mixed Climates


Applicable to skylights, windows, facades, indoor swimming pools, restaurants and any other glazing application where glass condensation is problematic.



Excessive indoor humidity is a well-known risk factor for buildings in cold and mixed climates. It is bad for health and bad for business. Museums, Art Galleries, Schools, Healthcare and Libraries in particular are at risk.


Maintaining an indoor climate of the air continuously humidified at 40 to 50% RH at 70°F (21°C) may seem reasonable, but that does not take into affect condensation over many weeks in cold climates. This is caused by the high DPT versus the low R-value of the glazing and in some cases, an even lower R-value of the window frames.


Dew point temperature (DPT) is the temperature at which a moist air sample at the same pressure would reach water vapor "saturation."
