Homeowners who opt to build new construction homes with double pane windows or replace single pane windows in existing structures experience many benefits immediately after installation including: Learn more about glass types on our “All About Glass” page. To further improve the insulating properties of the window, Glass Doctor offers IGUs with argon or krypton gas in the air space and Low-E glass. The twin panes are held in place with a spacer made of moisture-absorbent material called desiccant and the entire unit is sealed to prevent the inner air chamber from escaping. The air pockets in an IGU reduce the windows conductivity resulting in a better-insulated home. Single pane windows do not have air pockets heat passes through glass more readily than air.

The Science Behind Modern UnitsĮven though double pane windows are more expensive, given the choice, most homeowners who can opt to install double pane windows or IGUs, which keep your home insulated during the harsh summer and winter months. IGUs keep warm air indoors during heavy winters, cool air in during humid summer and your home quieter all year long. Twice as efficient as a single pane window, IGUs are designed to reduce both energy loss and outside noise, such as street traffic.

However, a full misty window will need a complete replacement immediately.įind out more about condensation with our window experts at Renewal by Andersen of Kansas City. Normally, for minor condensation issues, you may need to replace only the pane. In fact, this solution is simply a means to control the symptoms of a much bigger problem. However, drills can leave burs or sprue-like residue that might be an issue for sliding windows or other similar types. Some contractors would drill a hole in the glass of the window itself and then manually remove the moisture through the hole. Unfortunately, it’s difficult to stop condensation from happening. If the sealant is worn out, or the silica gel becomes too saturated, water starts to accumulate in the gas, causing all kinds of issues.
Typically, the condensed water is absorbed by the silica gel in the sealant. This condensation is akin to the condensation on the outside of a cold glass when left out under the sun. CondensationĬondensation in double-pane windows happens when there’s a critical difference between the temperature levels inside and outside the glass pane.
When the sealant breaks, the desiccant begins to absorb higher amounts of moisture until it’s saturated. This constant expansion and contraction eventually wear out the window, particularly the sealant in its perimeter. Alternatively, in the evening, the heat leaves the panes and the glass contracts. During the day, sunlight heats up the glass and causes it to expand. This is why it’s slightly more difficult to open double-hung windows at noon than it is at night. Glass undergoes this phenomenon, although at an extremely unnoticeable rate. Cooling an object has the opposite effect. You’ve probably learned in basic science that heat can make objects expand. Today, Renewal by Andersen® of Kansas City explains how and why condensation happens and what you can do about it.

How to Fix Condensation Issues in Double-Pane Windows The silica strip is placed throughout the perimeter of residential windows but it’s not uncommon to find it in other types of windows as well. The desiccant is often made from silica gel, the same substance you’ll sometimes find in small packets packaged with certain items. This gas is sealed with a desiccant that stops moisture from getting inside the tiny space between the panes.
High-efficiency double-pane windows are built with an insulating gas, typically argon, sandwiched between two glass panels.
