Simonton Offers New Condensation Brochure

December 6, 2011

"Understanding Condensation in Your Home" is the name of a new brochure introduced by Simonton Windows. It is available for download from the manufacturer's website.

“We often get calls from homeowners who are concerned that their windows are ‘sweating’ or leaking either inside or outside the home because they see moisture on the glass,” says Christopher Burk, Simonton's technical product manager. “In reality, that’s simply not the case. While condensation may collect on the interior or exterior of energy-efficient windows, the units are really doing their job by helping serve as a barrier in the home.”

Burk emphasizes that windows do not cause condensation–they simply prevent the moisture in the home from escaping to the outside. “If the inside glass surface on double- or triple-glazed windows show excessive moisture, you can be reasonably sure that the moisture is also collecting on your walls and ceilings,” says Burk. “This means you should take steps to reduce the humidity level in your home by using exhaust fans and dehumidifiers.”

The manufacturer notes that homeowners create much of the water vapor in the home themselves on a daily basis. It also offers a number of tips to reduce condensation:

  • Use kitchen and bathroom exhaust fans.
  • Set humidifier, if used, to the correct outside temperature.
  • If a home is overly humid, or if the basement is damp, use a dehumidifier.
  • Properly vent clothes dryers, gas appliances and stoves.
  • Open a window in the bathroom.
  • Make sure the attic, basement and crawl spaces are well ventilated and free from obstructions.
  • Store firewood outside. Freshly-cut wood can consist of up to 45 percent water, which adds water vapor to the home. Even well-seasoned firewood generally has a 20 to 25 percent moisture content.
  • Open curtains and blinds to allow more air circulation around your windows.

Simonton's Burk also points out that it is important to know the difference between condensation on the glass and between the glass panes of the window. “If you are seeing moisture, fogging or cloudiness between the panes of glass in your window, this is a strong indication that the seal of your window has failed and it’s time to get a new window,” he says. “Failed seals lack the energy efficiency and features necessary to help you keep energy bills low and enjoy comfortable living in your home. While condensation on the interior or exterior of the glass is manageable, moisture between the glass needs swift attention by homeowners.”
