Preventing Concerns With Secondary Glazing And Condensation

January 4, 2012 · Posted in Real Estate 

Today, men are able to build just about anything. There are many modern majestic structures throughout the world. Once a structure has been finished, it is on the the next project. Our cities continue to grow larger, and the building grow older. Many older buildings have been given historic status. They are provided with a sprucing up that holds true to their architectural standards, requiring them to maintain the good old wooden windows or they can be replaced with brand new ones. Many builders add secondary glazing as an attempt to increase the effectiveness of the windows, but there is the potential for problems with secondary glazing and condensation.

Secondary glazing is simply an extra glazing panel that is placed on the inside of an already existing single glazed window. It is usually a single glazed piece of glass, but can sometimes be shrink wrap or a plastic film. It is usually surrounded by a metal frame that incorporates a gasket or membrane in order to create an air space that is sealed between the new glaze and the old.

Although some people may be unfamiliar with all that secondary glazing entails, they do know what condensation is and how it happens. With windows, because they are glass, the interior and exterior temperatures are different, causing the moisture that is in the air by the glass to become cool and create a layer of condensation on the surface.

Humidity and moisture are two of the most important things to avoid when it comes to wood windows. Both result in the wood becoming warped and rotten, and can cause mold to grow as well. Many times, these issues are not identified until is is much too late, and then the window has to be entirely replaced.

Secondary glazing is not to be confused with double glazing, which is usually vacuum sealed in a factory environment that is moisture controlled. Secondary glazing traps regular, moist air, between the glazing and the single glazed window. Windows that are drafty will allow moisture from the outside to come in, and in the right conditions, the moisture creates condensation between the glass and settles at the bottom of the window. This greatly increases the odds that the window will rot.

The metal frame of the glazing panel also can be a culprit. Just like on glass, metal transfers temperature to the air and is likely to have moisture on it as well. While the moisture on the glass is easy to see, what is on the metal, especially between the panes, is much more difficult.

Wood windows that have failed due to moisture need to be replaced immediately. This can be very costly and labor intensive. So, when it comes time to look at how to weatherize windows, it is important to weigh all options available, looking at the positives and negatives, and decide which one is best.
