There are many different types of windows including single glazed and double glazed windows. Many times, people will install single glazed windows in their home but then want the additional benefits that a second layer of glazing can give them. There can be problems with secondary glazing and condensation that you need to be aware of. Here is information about windows in general and what you need to look for if you do decide to add secondary glazing to your wooden windows.
If you wonder why many people prefer double glazed windows in any new installations you may not know that they offer a lot of insulation against both temperature changes and sound. They are particularly useful in a room where there is a lot of glass exposed to the outside air. This can include a glassed in porch or a conservatory. Even a room with a lot of large windows can benefit from double glazed windows.
The structure of double glazed windows is quite simple. They are made up of a framework which contains two panes of glass. These are positioned quite closely to one another. During manufacturing, a layer of gas is sealed in between the two panes and this prevents any moisture from building up since it is an occupied space and there is no room for water vapor.
Secondary glazing is created in a slightly different way. Working with an existing window, a second thin layer of glass is added, usually in a separate frame. It is often created in such a way that it is identical to the outside window. The problem is that unlike double glazing, there is no gas layer other than a layer of air. Since air can hold moisture, this can be a problem where condensation is concerned.
Condensation occurs any time when there is water vapor present. It is usually invisible when the air is hot enough. However, should it meet up with a cooler surface such as an external pane of glass, the water can reform into water droplets and end up rotting through a wooden frame.
There are ways that you can avoid the build-up of condensation between your window panes. The first is to ensure that the window frame was completely dry before you had the second layer of glazing installed. If that is not the issue, you need to make sure that you are providing ventilation for the moisture to escape. In warmer weather, you can leave a window slightly open or you can choose to drill a ventilation hole so that the moisture can escape.
Your windows are an important part of the structure of your home. They can prevent the loss of heat to the outside and can prevent things that you do not want to get in from getting in to your home. If you do decide to install secondary glazing, make sure that you deal with a reputable installation expert that can get you the right products and can minimize the chances of moisture build up.
