Condensation on windows during the winter months is a common issue in many homes. It occurs when warm, moisture-laden indoor air comes into contact with the cold surface of the window glass. As the warm air cools down upon contact, its ability to hold moisture decreases, and the excess moisture is released, forming water droplets or condensation on the window surface. There are several factors that contribute to window condensation in winter: High indoor humidity: Everyday activities like cooking, showering, and doing laundry can increase the moisture level in your home. If the indoor humidity is too high, condensation is more likely to form on cold surfaces like windows. Inadequate ventilation: Poor ventilation can trap moisture inside your home, leading to higher humidity levels and an increased likelihood of condensation on windows. Cold outdoor temperatures: When the outside temperature drops significantly, the window glass becomes colder, increasing the chances of condensation forming when warm indoor air comes into contact with it. Inefficient windows: Single-pane windows or older, inefficient double-pane windows can be more prone to condensation due to their lower insulating properties. To reduce condensation on your windows in winter, consider the following steps: Control indoor humidity: Use exhaust fans in bathrooms and kitchens to remove excess moisture. Run a dehumidifier if necessary to maintain an indoor humidity level of around 30-50%. Improve ventilation: Ensure your home has proper ventilation to allow for the exchange of indoor and outdoor air. You can also use an HRV (Heat Recovery Ventilator) to improve ventilation while maintaining energy efficiency. Insulate windows: Upgrade to energy-efficient double or triple-pane windows, or add insulating window film or thermal curtains to reduce heat loss and keep window surfaces warmer. Seal gaps and drafts: Inspect your windows for any gaps or drafts and use weatherstripping or caulk to seal them, preventing cold air from entering and reducing the risk of condensation.
