Upgrade Your Windows This Winter 1

Is Condensation on My Windows Normal?

Did you just replace your old windows, and now you’re waking up to fog?

Don’t panic! The experts are here to tell you that moisture on the inside of your windows can be completely normal as we welcome in fall’s crisp air.

 

Where is condensation coming from? 

While the temperatures drop in New England, we as inhabitants start to close up our homes. We close our windows and doors with the goal of keeping the cold air out. The problem we face when we tighten our homes is the temperature difference we create between inside and out. Outside is cold and dry and our interiors, in contrast, are warm and humid. And just like a cold glass of water that collects condensation during a hot summer day, the same thing happens to our windows. Simply put, when warm humid air meets a cold surface, like the glass of our windows, condensation will occur.

The truth is, ironically, condensation is more prevalent in newer homes or homes with newly installed energy-efficient windows. The better, more air-tight design of the home and the measures we take to weatherproof, make it harder for moisture to escape, forcing it to condense on our windows.

“Many homeowners become concerned about the window’s quality or effectiveness when they experience condensation for the first time, more so than their old ones, but the truth is that condensation is actually a sign that your windows are doing their job. Your old windows weren’t better, they were just less energy efficient.” Brain Cormack, Window Expert at JB Sash”

 

Here are 3 tips to help lower indoor condensation.

 

1. Use your exhaust fans

They are there for a reason. If you are cooking up a steamy pot of soup or taking a hot shower, be sure to turn on the exhaust fan to help the moisture escape from the air. The pros say that leaving the fan on for 20 minutes after cooking or showering will help.

 

2. Lower your humidifier

If you are running a humidifier this winter as most people do, we recommend that you keep your humidity level at 60% or lower.

 

3. Keep the interiors open

Leave your interior doors open and turn on your ceiling fans to help circulate the air. The goal is to not let the humidity build up in one space.
