Condensation or frost on the inside surface of the glass or window does not indicate a defect in the window and is not covered by the warranty.  Condensation occurs when warm moist air comes in contact with the colder surface on a window.  It is a response to temperature and humidity in the home and is not the fault of the window.  Since we use the warmest edge glass spacer (Super Spacer), you will have much less, if any, moisture on the inside surface of your glass.

What causes high indoor humidity levels?  Simply said, moisture is caused by everyday living.  Dishwashers, washing machines, furnaces, humidifiers, cooking, and showering are all major contributors to humidity. 


Controlling the humidity levels in your home may seem difficult.  Try these nice ways to reduce humidity levels:

  • Shut off all household humidifier units (including the furnace humidifier)
  • Ventilate regularly.  Air out your entire home for a few minutes each day.  Ventilate your kitchen, laundry, and bathrooms during use.
  • Run exhaust fans longer and more often
  • Open the fireplace damper
  • Be sure attic and basement crawl space louvers are large enough and open
  • Add a basement dehumidifier
  • Adequately vent humidity producers such as clothes dryers and all gas burners to the outdoors
  • Open draperies and blinds so air is able to circulate next to the window
  • Bay/Bow: Place a small fan in the window to circulate air
