When the air gets colder it cannot hold all the moisture, and tiny drops of water appear. This is called condensation. You may notice condensation when you see your breath on a cold day or when the mirror mists over when you have a shower.

Condensation happens more in rooms where there is a lot of moisture, such as bathrooms and kitchens.

There are 4 main causes of condensation:

• excess moisture produced by everyday activities
• inadequate ventilation.
• insufficient heating
• insufficient insulation.

Preventing condensation is about getting the right balance by reducing excessive moisture, adequate ventilation, sufficient heating and sufficient insulation.
