Condensation occurs when warm, moisture-laden air comes into contact with a colder surface such as glass. The air temperature in contact with the colder surface suddenly drops, reducing the amount of moisture it can hold. This results in moisture formation, or condensation, occurring on the cold surface. Condensation causes damage to interior paintwork, the inside surface of wall linings, floor coverings, curtains, and furnishings. It results in increased heating costs (as additional energy is required to convert condensation back into vapour which is taken up by the air as the temperature rises), and presents a health hazard.
MOLD & BACTERIA GROWTH CONTROL
High humidity is not only uncomfortable, but it creates a breeding ground for mold and bacteria. If humidity is not controlled then it will lead to unhygienic conditions and this may cause severe diseases to people. If moisture gets into insulation, this insulation will not work well as it should have been, and ones heating and cooling bills will tend to increase significantly.
One of the major effects of moisture is that it leads to change of shape of furniture. It is therefore important to produce and deliver timber products dried to the moisture content appropriate to the construction site. Dehumidifiers do not let the shape of timber to get changed due to moisture.
