Window Condensation, Part 1: 7 Basic Facts

Condensation is one of the most common issues homeowners face nowadays. This happens when warm air comes in contact with a cold surface like your window. The excess moisture in the air condenses on the surface and creates droplets of water. To help you understand condensation, here are 7 facts from Renewal by Andersen® of Central Illinois, your provider of windows in Peoria, IL:

  1. Activities like cooking contribute to indoor moisture. Plants, oil, and natural gas also contribute to water vapor in the air. This, in turn, increases indoor humidity.
  2. Damp spots on the ceiling and paint blisters indicate that your home may be too humid.
  3. Too much humidity can affect your health. The World Health Organization reports that high humidity levels can cause respiratory illnesses and skin issues.
  4. Humid rooms can also damage your window’s frames and sash.
  5. You don’t have to worry if condensation forms on the outside of your window. This means that you have energy-efficient replacement windows in Peoria, IL. The glass surface maintains a consistent temperature all day because it’s insulated from the inside.
  6. Your windows can also indicate high levels of humidity. If condensation forms on the interior glass surface, the room is too humid. Outdoor temperature can also lead to condensation on windows.
  7. If you find strips of condensation around the window frame, don’t fret. This means that your windows have components that transmit cold outdoor temperature to the inner glass. This results in condensation on the glass surface. This does not indicate that your windows have leaks.

Proper ventilation is an ideal way to maintain relative humidity levels inside your home. You can do this by investing in exhaust fans in kitchens and baths or attic ventilation. You can also invest in energy-efficient window installation in Champaign, IL, from Renewal by Andersen.

"I would recommend RBA of Central Illinois for QUALITY windows and doors. Compared to our old cheap, thin vinyl windows, Andersen blows them away. You can easily tell by how well the sliding doors fit and close, and how heavy duty they are. We also cannot hear the wind rushing through the house in inclement weather anymore! And the black window frames we went with are amazing to look at. Aaron, Al, Darrell, and Cory all were professional and went all out to finish the job, given the weather they had to deal with. I would definitely recommend. They were also on top of communicating with me given the weather delays, and what I could expect for them coming out. Five stars!"
