Moisture is always present in the air, even if it is not visible. You might notice it when a mirror fogs up after a bath or shower, or when you see your breath on a chilly day.
Warm air can hold more moisture than cold air. But when warm air encounters a cold surface, like a wall or window, it cannot retain all the moisture, leading to the formation of tiny water droplets. This is condensation.
Condensation occurs when the air in your home becomes too cold or when you generate excess moisture through activities like cooking, showering or doing laundry.
Condensation is the primary cause of dampness and mould in homes. It typically forms on cold surfaces or in areas with limited air circulation, such as windows, room corners, and small spaces behind furniture.
To prevent mould, it is important to wipe dry any condensation that appears on windows or doors.
Condensation can cause significant damage to surfaces and window frames, and it often leads to the growth of mould. Mould is not only visually unpleasant but also poses health risks. Mould can trigger allergic reactions and worsen asthma symptoms. Also, humid conditions create an environment that can help bacteria and viruses to spread and can encourage the presence of house dust mites.
