Condensation: Are My Windows the Cause?

Condensation: Are My Windows the Cause?

What’s Condensation?
Condensation is the result of high humidity levels. It happens when warm, moist air touches a surface that’s colder than the dew point. Dew point is the temperature at which air becomes saturated and produces dew. As the air temperature drops below its dew point, excess moisture appears on the colder surface. So, what does all of this mean? Condensation is not caused by faulty windows. Windows provide a surface for moisture to condense on, warning you there is too much moisture in your home.

Humidity Factors
Several things add moisture to the air in our homes. Breathing and perspiration adds 3 pints of water per person into the air every day. In fact, every activity that uses water increases the level of moisture in the air. This includes cooking, laundry, taking showers, and washing dishes.

Damp air in your home may not seem like the most pressing issue in the world. However, it can lead to more serious problems including mold, rotting wood, and insect infestation. It’s potential threats like these that make controlling the humidity in your home so important.

Controlling Humidity
Ventilation is the key in allowing moisture and humidity to escape your home. Houses are now made tighter than ever; with housewrap, insulation and well-crafted windows from Harvey Building Products, proper steps need to be taken to control humidity.

Tips to increase air circulation:

• Turn on vents when using gas burners and clothes dryers
• Install exhaust fans in the kitchen, bathrooms, and laundry room
• Use a dehumidifier
• Install a roof ridge vent and soffit for attic ventilation
• Install foundation vents

Temporary Condensation
Wood, plaster, cement, and other building materials produce a great deal of moisture. Concrete foundations can take up to a year to completely dry out. Rapid drops in temperature can also create temporary condensation problems during the heating season.

The Bottom Line
Your windows do not cause condensation! Condensation is the result of high humidity in your home. The important thing to realize is that condensation on your windows is a warning sign. With proper ventilation, you can eliminate the problem before it causes any major damage to your home.
