Overview:
- Condensation is the result of a simple law of physics. Vapor will turn to liquid when it comes in contact with any surface that is at its dewpoint or lower. The dewpoint is determined by the air temperature, its pressure, and the amount of water vapor in the air (relative humidity).
- No way to completely eliminate condensation.
- Average home produces 20 gallons of water per day into the air of the home just from washing, bathing, cooking, etc..
- The window is only a "symptom" of a home that’s too humid.
- Aluminum windows have cooler surfaces than wood or vinyl windows, so they’re the first to show condensation.
- Even with vinyl or wood windows, condensation can be apparent when a home is not properly ventilated.
- Condensation can also appear on outside surfaces when a higher performing glass type is used. This glass can allow the outside surface to reach the dewpoint, because it reflects the heat back indoors and off the glass surface. As outside air temperature increases, the outdoor condensation should diminish. You will mainly see this challenge in the morning hours. This is the same phenomenon that is observed on your lawn, outdoor furnishings, or your car windows when left out for the evening.
Solution Ideas for indoor condensation
Glass
- Low-E Glass will have a warmer interior surface which will help reduce the forming of condensation.
- Heat Mirror will have a warmer interior surface which will help reduce the forming of condensation.
- Argon gas will result in a warmer interior surface which will help reduce the forming of condensation.
Frame
- Vinyl Windows have a warmer frame surface which will help reduce the symptoms of condensation.
- Wood Windows have a warmer frame surface which will help reduce the symptoms of condensation
Other Considerations
- CAUTION: Do not oversell benefits of our products against condensation. A home that is too humid can show condensation on the windows, the floors, even the walls.
- Suggest ventilation systems in heating/cooling equipment or wall vents, fans, etc. to help minimize the humidity of the home.
