Guide to Moisture and Humidity
Many homes suffer from condensation and mould growth. If serious moisture problems are ignored, permanent damage can occur to a home’s windows, interior finishes, and structure. Prolonged exposure to some moulds may also cause health problems.
What Causes Moisture Problems?
Condensation occurs when humid air is cooled below its “dew point.” Mould growth usually occurs on any surface that remains wet or damp for a prolonged period of time. The two factors that determine whether condensation will or won’t occur are the “relative humidity” of the air and the temperature of the various cold surfaces (particularly windows) in the home.
