There are double and secondary glazing options for stopping condensation on room-side glass with a U-value of up to 1.35. Well sealed frames ensure minimal air leakage and trap an insulating layer of air, reducing heat loss by 40-50%. You can make it 60% if you use low-E glass. If you want triple glazing, you can install sealed units.
Because of their minimal thermal insulation and very cold surface, single-pane windows are always liable to condensation. The best way to cure condensation is to install energy-efficient windows and ensure good ventilation along with the four lifestyle changes mentioned above.
Stopping condensation on windows
Lack of ventilation is the main reason for condensation. The solution is to improve ventilation to equally indoor and outdoor humidity. Before, houses had a lot of air vents, chimneys, and poorly fitted windows. Since the last thirty years, houses have become significantly more energy-efficient, and many homes have become sealed units that trap humidity. We’ve made our homes better at keeping the heat in, but we’ve lost natural ventilation.
A condensation problem inside double glazing
The most common cause of window condensation is excessive humidity. Window glass gets colder as the temperature outside drops. A cool glass pane makes water droplets when moist air hits it. The surface temperature of double glazed windows is often cooler than the air in the room, which causes condensation. Warm air can go through the gap between the glass panes if the sealant around the double glazing has failed.
Window condensation is a big deal. It’s tough to keep up with condensation around windows, especially when it rains because it will leave watermarks on the window. Keep an eye on the sealant around windows as any damage will allow water to enter. This is the best way to prevent condensation around windows. Clean windowsills to ensure moisture doesn’t sit in your property’s air and open your windows as much as you can to let fresh air in.
