All air contains a certain amount of moisture, even indoors. And there are many common things that generate indoor humidity such as your heating system, humidifiers, cooking and showers. In fact, every activity that involves water, even mopping the floors, contributes moisture to the home.
Condensation is more likely to occur in homes where January temperatures drop below 35F because there are greater temperature extremes affecting the glass in the home. It is very normal to experience condensation at the start of each heating season. During the humid summer month your home absorbs moisture and then perspires when you turn on the first few week of heating your home should dry out, reducing if not eliminating condensation. You’ll notice the same remodeling or building. Due to the high levels of moisture in wood, plaster and other building materials, your home will temporarily sweat during the first few weeks of the heating season.
Another factor in the condensation equation is progress. With today’s modern insulation, moisture-barrier materials and air-tight construction, we all enjoy a more thermally efficient home-one that block the cold out, yet traps the moisture in producing higher humidity levels and…. more condensation.
