Eliminating Condensation Problems in Your Home

Do you have questions about condensation?

Condensation on windows

Condensation on windows is an unattractive and damaging problem that primarily affects buildings in colder weather climates.  Fortunately, in almost all cases Indow Windows reduce or eliminate condensation.

Condensation reduces visibility, can be difficult to clean, and may damage your windows, curtains, walls, and/or carpets. In worst-case scenarios, persistent condensation causes mold to form and can rot the muntins in your windows.

Window condensation occurs when the temperature of the glass drops below the dew point of the adjacent air.  When the air temperature drops it reduces the ability of the air to hold moisture. The air voids the water molecules in a manner similar to water squeezing from a sponge.  Interior air is typically warmer and holds more moisture than exterior air due to human breath, plants, showers, pets, and other moisture sources.  When warm interior air touches a cold glass surface the air temperature drops and condensation occurs.

Why do my windows have condensation?Condensation on windows

“Window condensation occurs when the temperature of the inside glass drops below the dew point of the adjacent air,” says one of our Illinois dealers, Energy 360 Solutions.

“Window condensation can be caused by a variety of factors – excess moisture in the air, inadequate ventilation, temperature differentials, inefficient windows, and more.”

In other words, condensation occurs when cold outside air is absorbed by the glass, and then makes contact with the warm, moist air in the home. The more moisture, the more you may see this effect. This is why there are a higher number of problems in bathrooms and kitchens.

This temperature difference is the main issue that any solution will try to overcome. The National Fenestration Rating Council recently released a report that states, “to increase resistance of windows to the formation of condensation, it is important to maintain the surface temperature of the window above the dew point.

This reduction of the heat transfer is called the U-factor, or thermal transmittance. The higher the U-factor, the more likely condensation will form.

How do Indow Windows reduce window condensation?

The primary place condensation can occur is on the inside surface of the existing windows. Indow Windows are edged with our patented silicone Compression Tubing, and form a near airtight seal around the inside of the window opening.  Typically existing windows will leak significantly more exterior air into the cavity than the Indow Window will leak interior air.  This means that the air within the pocket is comprised mainly of exterior air that warms in the cavity, rather than interior air that is cooled.  This warming of the air expands the air’s capacity to hold water rather than constricts it and therefore Indow Windows will significantly reduce if not eliminate condensation on the surface of the existing windows.

Condensation almost never occurs on the surface of the Indow Windows.  The air pocket between the existing window and the Indow Window buffers the acrylic glazing from the outside temperatures, allowing a more neutral temperature to be maintained within the air pocket.  In addition to the air pocket, Indow Windows are made of a high-grade acrylic, which is a far superior temperature insulator than glass. The difference is very noticeable to the touch.  Since the interior surface of the Indow Window is much closer to room temperature it greatly reduces the risk of condensation.


Indow Windows are easy to install and help reduce condensation in high-moisture areas like your kitchen
