DO YOU HAVE WINDOW CONDENSATION?
To stop window condensation, you need to know what causes condensation on windows. This nuisance takes away your view and can cause serious damage to windows and walls. All that moisture can lead to rot, mold, and mildew, as well as lift up paint and damage plaster.

WHAT CAUSES CONDENSATION ON WINDOWS?
Window condensation forms when the interior surface temperature of your windows is at or below the dew-point temperature of the surrounding air in your house. What’s the dew point? That’s when the air is no longer able to “contain” all the water vapor mixed with it. Some of that water vapor has to say “see ya”, so it condenses into liquid on the window pane.
Think of the air as a sponge holding water: when the temperature drops, that squeezes the sponge onto the interior surface of your window.
WHAT FACTORS CAUSE CONDENSATION ON WINDOWS INSIDE YOUR HOUSE?
- Inside and outside temperature
- Relative humidity of a space
- Humidity inside the home can be raised by: breathing, pets, showers, and plants to name a few
As the air cools outside, it may cause the interior surface of your windows to fall beneath the dew point. If all other conditions are equal, window condensation will occur more quickly in a space that’s more humid.
SOLVING WINDOW CONDENSATION WITH INDOW WINDOW INSERTS.
To fix condensation on windows inside the house, you must make the inside and outside temperatures closer to one another. You must also stop moist air from touching the window glass. Window inserts stop moist air from touching the glass pane and keep the air around it at a relatively similar temperature.
Indow inserts are made of a high-grade acrylic that insulates better than glass. The inserts have a silicone edging that press into the interior of your existing window frames to create a near airtight seal so the moist interior air of your house can’t get to the glass window pane. The air in the cavity between the acrylic insert and your glass window also buffers the insert from the cold outside temperature.
Single-pane windows often get more window condensation than double-pane windows, but it can happen to both types of windows. Indow inserts can help solve condensation on both single and double-pane windows.*
Here is a great picture a customer sent of a clear window with an Indow insert right next to a foggy, wet window without an insert:

*Indow window inserts will reduce or eliminate condensation on windows in most cases, but not all. Sometimes structural issues can interfere with the ability of the inserts to solve the problem.

Thanks for this advice for window condensation. It’s interesting to learn that window inserts can stop moist air from touching the glass pane. I’m kind of interested to learn how big an insert could be or if it could depend on the window.
Hi Taylor! We can go quite large with a single insert, 6×8 or 5×10, but we have something called a mullion which can be installed to break a large window opening up into multiple panels. With that accessory, we can do almost any size.
Wow, I thought it was interesting when you explained that we can contribute to the humidity in our home by breathing. For the past couple of days, one of the windows in my kitchen has been sweating a lot. I don’t know if we are causing this, or if there is a problem with the seal. It seems like it would be a good idea for me to contact a repairman just in case.
