Double-glazing has a variety of benefits that make it a must-have for modern homeowners. However, one of the less talked about – and perhaps less considered – benefits they carry, is in how they reduce condensation.
In this article, we explore what condensation is, how it occurs, why you don’t want it in your home, and how double-glazed windows reduce it from happening.
What Is Condensation?
Condensation is the build-up of moisture on a surface. It typically occurs on windows and other surfaces where there is a significant heat difference between it and its environment. To the naked eye, it appears as if water forms on the surface from nothing. After all, it can happen even if there aren’t any liquids nearby.
What is actually happening has to do with the heat differential between the air and a given surface. Moisture is ever-present in the air, invisible to plain sight. How much moisture air can hold depends on its temperature. The hotter the air, the more water particles it can hold.
The process of condensation begins when:
- The water in the air comes into contact with a surface that is a lower temperature than itself.
- The air is chilled at the point of contact with the surface.
- The cooled air can no longer hold as much water moisture, so it sheds the excess particles.
- The surface catches those water particles, forming a mist or full droplets depending on how many water particles there are.
Condensation in windows occurs when the outside temperature is lower than the inside of a building. The outside temperature cools the glass, creating a cold surface. Warm air inside your home makes contact with the glass and sheds its moisture. Over time, this causes the window to mist over and eventually form full water droplets, depending on how much moisture is in the air in your home.
Why is Condensation Bad?
By itself, water on your window is harmless as glass is waterproof.
The rest of your home, however, is not.
As water droplets form on the inside of your window, gravity takes hold and they run down the glass. They interact with sealant, paint, curtains, blinds, and other object you would rather avoid coming into contact with water.
Over time, this exposure to water wears away at your sealant, causes damp within your home, and degrades paint. All of which are undesirable and potentially expensive to repair or otherwise remedy.
How Does Double-Glazing Reduce It?
Double-glazed windows are special in that they are actually two panes of glass with a thin barrier of air between them. This cushion of air acts as an insulator between the inside and the outside of your home. The cold from the outside cools the exterior while the heat from the inside cools the interior. The heat differential is then equalised within the air cushion.
All of this inhibits condensation. The interior pane of glass doesn’t cool, which means that it cannot catch the moisture in the air.
