Recently, due to the extreme cold weather outside in our Midwest region of the country we live in, we have had many calls come in for window condensation issues. Below are simple guidelines to help solve the issue.
- Make sure inner windows are properly sealed. Otherwise, moist air will leak to the outer storm window and condense. Check that the windows are closed tightly with sash locks firmly latched. Use plastic film kits on troublesome windows to increase comfort.
- Check that warm air is getting to the windows. Is furniture blocking warm air registers? Also, open blinds and shades occasionally. Closing blinds and drapes-though a good way to save energy can worsen condensation problems by cutting off the flow of warm air past the windows.
- Consider adding storm windows or replacing your windows with more energy efficient units, especially if your old windows are single pane or aluminum-framed. Efficient windows are much less likely to show condensation because the glass stays warmer.
- Shop around for units displaying the ENERGY STAR label. These products meet the highest standards of energy efficiency in their category.
- Windows are expensive, but it might be worth it to consider window replacement as part of a whole house approach to solving all your energy and moisture problems.
