The document outlines ten methods to prevent window condensation, particularly during winter, which can cause long-term damage if not addressed. Suggestions include improving ventilation, maintaining a consistent warm temperature, using lids while cooking, and avoiding drying laundry indoors. Additionally, it advises on better insulation practices and replacing windows with condensation between panes.

2. How does window

Condensation on windows commonly happens,
especially during winter.

3. Can it effect window in

Condensation on windows is natural, but not
doing anything about it could prove to be
harmful in the long run.

7. Improve ventilation
Open windows when you can to allow air to
circulate. Install extractor fans, especially in the
kitchen and bathroom where humidity is
constantly high

8. A consistent warm
temperature inside
By maintaining a warm temperature, even on
low settings, you can ensure that surfaces
remain well above the dew point so that
condensation doesn’t occur.

9. Keep kitchen and
bathroom doors closed
These are the most humid areas of the house, and
when you keep them open, you draw moisture
from these rooms to the rest of the house.

10. Use lids when cooking
Steam is released while cooking, contributing to
the moisture in the air. Whenever cooking, use
lids to cover pots and prevent steam from
escaping too much.

11. Don’t dry laundry inside
the house
Drying one full load of damp laundry releases
almost 5 pints of water in the air. If you can, dry
laundry outside the house.

12. Invest in better insulation
If condensation is a recurring issue, consider
reinsulating your walls and installing new
windows

13. Turn on your ERV/HRV unit
Modern houses are built s airtightly to prevent
drafts from entering. This can cause poor air
circulation and too much humidity.

14. Avoid blocking your windows
Closed drapes trap moisture and heat on
window panes. They block air movement across
glass surfaces allowing cool air to pool at the
window sills.

15. Exterior condensation
If you want to prevent exterior condensation,
consider placing tall trees and shrubs to create
a shaded area near your windows. This traps
heat and prevents exterior condensation.

16. Replace your windows
Condensation between two window panes
indicates unit failure. The window unit already
has a leak that allowed moisture to get inside
the air gap.
